INTRODUCTION

This case presents a square conflict over an important question of appellate procedure: Whether a

court of appeals may override the principle of party

presentation by deciding sua sponte a non-jurisdictional

issue that a party deliberately waived.

In the decision below, the Federal Circuit—which,

along with one other circuit, holds that “it is a discretionary decision to forgive waivers of non-jurisdictional

challenges,” Ciena Corp. v. Oyster Optics, LLC, 958 F.3d

1157, 1161 (Fed. Cir. 2020)—sua sponte raised and resolved the appeal on an issue that neither party presented or briefed and that respondent WhereverTV, Inc.

deliberately and repeatedly waived. App. 1a-22a. The

court went so far as to hold that the district court “legally erred” by not addressing the waived issue. App.

12a. Had this appeal arisen in the Eleventh Circuit or

one of three others holding that “courts must respect”

when “a party affirmatively and intentionally relinquishes an issue,” it would have come out the other way.

United States v. Campbell, 26 F.4th 860, 872

(11th Cir. 2022) (en banc). The same is likely true had

this appeal arisen in the remaining seven circuits, although they apply different standards to override waiver

in limited circumstances: WhereverTV’s deliberate

waiver would have been respected and petitioner Comcast Cable Communications, LLC would have prevailed.

The Federal Circuit’s approach to waiver cannot be

reconciled with this Court’s precedents and the party

presentation principle. “[W]e rely on the parties to

frame the issues for decision and assign to courts the

role of neutral arbiter of matters the parties present.”

United States v. Sineneng-Smith, 590 U.S. 371, 375

3

(2020) (quoting Greenlaw v. United States, 554 U.S. 237,

243 (2008)). “If a party passes up what seems to us a

promising argument, we do not assume the role of advocate.” Trump v. Illinois, No. 25-443, 2025 WL 3715211,

*1 (U.S. Dec. 23, 2025) (Alito, J., dissenting). Where a

party deliberately chooses to withdraw an issue from

the court’s cognizance, the court “abuse[s] its discretion”

by addressing it. Wood v. Milyard, 566 U.S. 463, 466

(2012).

The Federal Circuit’s drastic departure from the

party presentation principle and the courts of appeals’

divergent approaches to the question presented call for

this Court’s review.

STATEMENT OF THE CASE

1. Petitioner Comcast Cable Communications, LLC

is one of the nation’s largest providers of broadband,

wireless, video, and voice services. App. 24a. Under the

Xfinity banner, Comcast’s X1 entertainment system

provides users with a cloud-based interactive program

guide that allows them to access and watch media made

available by Comcast. Ibid.

Respondent WhereverTV, Inc. is a largely defunct

television company that owns U.S. Patent No.

8,656,431, titled “Global Interactive Program Guide Application and Device.” App. 2a. Aiming to free customers

from a “content middleman,” like Comcast, “who limits

or controls what content is available,” WhereverTV’s patented device allows users to “add, delete programming

channels in ‘real-time’ that might not be available

through subscribed to” cable companies. Resp. C.A. Br.

6-7 (quoting ’431 patent col. 2, 41-43); see App. 18a.

Through a fully “portable set top box,” it allows users to

do so “anywhere in the world”—hence the name

4

WhereverTV. See Pet. C.A. Br. 50 (quoting ’431 patent

col. 7, 29-30); App. 2a.

The key features of the invention are required by

claim 1 of WhereverTV’s patent (the sole claim at issue).

Claim 1 covers a “content manager device comprising,”

among other limitations, “an interactive program guide

application installed on the device that provides a userconfigurable interactive program guide (IPG)”—the socalled “installed on the device” limitation—that “allows

for the IPG to be configured by a user with respect to

adding or deleting channels”—the so-called “adding or

deleting” limitation. App. 4a-5a (quoting ’431 patent col.

16 ll. 32-54).

2. WhereverTV sued Comcast for infringement, alleging that Comcast’s X1 entertainment system infringed WhereverTV’s patent. App. 5a. Because WhereverTV alleged literal infringement, it had to show that

the “accused device contains each and every limitation

of the asserted claims.” SIMO Holdings Inc. v. H.K.

uCloudlink Network Tech. Ltd., 983 F.3d 1367, 1380

(Fed. Cir. 2021) (quoting Ericsson, Inc. v. D-Link Systems, Inc., 773 F.3d 1201, 1215 (Fed. Cir. 2014)). WhereverTV thus had to prove that Comcast’s X1 system satisfied both of the two limitations relevant to this petition: Namely, that the X1 system had “an interactive

program guide application installed on the device,”—

i.e., on the X1 system’s set-top box—that provides an interactive program guide, and that the X1 guide could be

“configured by a user with respect to adding or deleting

channels.” App. 9a.

There are “two elements of a simple patent case, construing the patent and determining whether infringement occurred.” Markman v. Westview Instruments,

Inc., 517 U.S. 370, 384 (1996). The first element—called

5

“claim construction”—can involve a “mongrel practice”

where the parties call on a court to resolve disputes

about the meaning of the patent claim’s terms. Id. at

378. If called upon, the court may, for example, “consult

extrinsic evidence in order to understand … the background science or the meaning of a term in the relevant

art during the relevant time period.” Teva Pharms.

USA, Inc. v. Sandoz, Inc., 574 U.S. 318, 331 (2015). Often, however, the parties or the court will determine

that no claim construction is needed. See O2 Micro Int’l

Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351,

1362 (Fed. Cir. 2008) (“[D]istrict courts are not (and

should not be) required to construe every limitation present in a patent’s asserted claims.”).

The construction (or not) of the claims, in turn, “dictates how the court will instruct the jury regarding a

claim’s scope.” Id. at 1359. The second element of a patent case—the determination of whether the accused device meets the patent’s limitations—is based on the patent’s claims as construed (or not) by the court. Markman, 517 U.S. at 384.

In this case, WhereverTV deliberately declined to

seek construction of the patent’s two relevant limitations. See App. 30a, 47a-58a. WhereverTV knowingly,

deliberately, and repeatedly urged the district court not

to construe those claim limitations and instead to use

the language of the patent itself to set the standard by

which infringement would be assessed. See generally

Akamai Techs., Inc. v. MediaPointe, Inc., 159 F.4th

1370, 1380 (Fed. Cir. 2025) (“When a claim limitation[]

… is not expressly construed, a jury is entitled to give

that limitation any reasonable meaning in determining,

as a factual matter, what comes within its scope.”).

6

WhereverTV never proposed a construction of either

limitation and insisted that claim construction was not

needed. At the Markman stage, WhereverTV advocated

that the language of both limitations should be read to

the jury as is. App. 51a-53a & n.4; see Resp. C.A. Br.

17-19. WhereverTV did so in the face of local rules requiring parties to exchange “proposed interpretation[s]”

and to submit a joint statement to the court identifying

any “disputed claim term[s]” for judicial resolution. See

M. D. Fla. Case Management Order for Patent Cases.

Neither party proposed a construction of the “installed

on the device” limitation—thus agreeing that the patent’s text could be used as the standard for determining

infringement without elaboration from the court. App.

47a-58a; Resp. C.A. Br. 18. And WhereverTV opposed

Comcast’s proposal for construction of the “adding or deleting” limitation. App. 56a. After briefing and a hearing, which included expert testimony, the district court

adopted WhereverTV’s position and did not construe either of the two relevant limitations. App. 56a; see Resp.

C.A. Br. 18-19 (The district court “correctly decided that

[the ‘adding or deleting’] limitation does not need construction.”).

The parties accordingly proceeded to a weeklong trial

on the second element of a patent case, “determining

whether infringement occurred.” Markman, 517 U.S. at

384. Because the district court—at WhereverTV’s insistence—did not construe either limitation, the text of

WhereverTV’s patent provided the standard by which

infringement would be judged.

After the close of evidence, the district court granted

judgment as a matter of law to Comcast. App. 44a-46a.

The court applied the plain text of the “installed on the

device” and “adding or deleting” limitations and held

7

there was insufficient evidence for a jury to find infringement of either limitation. The court’s reasoning—

initially provided from the bench, App. 44a-46a, and

later reduced to a written order, App. 23a-43a—was

straightforward. As to the “installed on the device” limitation, the court recounted evidence showing that Comcast’s interactive program guide application “is installed

and runs ‘on servers in the cloud,’” and thus “is not installed on the device (the set-top box).” App. 40a. As for

the “adding or deleting” limitation, the court described

evidence “regarding the rigidity of [Comcast’s] X1’s

[guide] display and the immutability of the channel listings provided by Comcast,” which inhibits “a user’s ability to add or delete channels.” App. 36a-37a; see ibid.

(Comcast’s X1 system is “in no way identical to the …

invention described in the [] Patent specification”).

The district court, in its written decision, made clear

that it had not engaged in claim construction and emphasized that WhereverTV had waived the issue. See

App. 30a (“WTV stated that the Court should use the

plain and ordinary meaning of ‘adding or deleting.’”);

App. 38a (“WTV suggested that this term [IPG] should

have a ‘plain and ordinary meaning’”). It observed that

“[o]n two separate occasions” before trial WhereverTV

“had the opportunity to move the Court to construe” the

claim terms, yet “did not do so on either occasion.” App.

30a; see App. 47a-58a (order on claim construction).

“Nor did either party move to have the [limitations] construed during trial.” App. 30a-31a. Indeed, WhereverTV, in opposing Comcast’s motion for judgment as a

matter of law, asked for the jury to weigh the evidence

against the plain language of the claim and argued that

Comcast improperly sought claim construction. App.

33a, 38a. For its part, Comcast agreed that claim

8

construction was unnecessary and inappropriate at that

stage. App. 30a-31a. As Comcast saw it, WhereverTV

could not avoid judgment as a matter of law on the patent’s plain language; the only way that the case could

be properly submitted to the jury was if the claims

meant something else entirely. App. 31a n.3. The district court honored WhereverTV’s deliberate waiver and

ruled on the only question before it, finding the evidence

insufficient to prove infringement.

3. On appeal to the Federal Circuit, WhereverTV

challenged only the district court’s determination that

the evidence did not suffice to show that Comcast’s X1

system infringed the two limitations as written.1

WhereverTV stressed that it never sought claim construction of either limitation and argued that the district court erred by improperly engaging in claim construction. Resp. C.A. Br. 31-32; see Resp. C.A. Br. 31

(“Neither party proposed a construction for IPG application because none was needed.”); Resp. C.A. Br. 47 (“No

construction was needed because adding channels is familiar to anyone who has subscribed to cable television”). Comcast agreed with WhereverTV that the sole

question presented to the court of appeals was whether

the evidence sufficed to prove infringement applying the

plain text of the relevant limitations without further

construction. Pet. C.A. Br. 42-46, 52-56.

The Federal Circuit vacated and remanded. App.

22a. But the panel did not address the issue presented

1 Comcast asserted an alternative ground for affirmance relating

to a different claim limitation and cross-appealed on an issue regarding the patent’s validity. Pet. C.A. Br. 58-70. The Federal Circuit rejected both of Comcast’s arguments, App. 18a-22a, and Comcast does not seek review of those independent issues.

9

by the parties: Whether the evidence sufficed to show

infringement of the patent as written. Nor did the Federal Circuit accept WhereverTV’s argument that the

district court erred by engaging in claim construction in

its judgment as a matter of law decision. Instead, the

Federal Circuit addressed an issue neither party raised

or briefed and that WhereverTV had repeatedly argued

against—whether claim construction was needed—and

held that “[t]he district court legally erred by not construing th[e] limitation[s].” App. 12a.

The Federal Circuit then engaged in partial claim

construction itself—without proposed constructions or

briefing from the parties, or a decision on the issue from

the district court. App. 15a-18a. First, the panel held

that the claim language “interactive program guide application installed on the device” “does not require that

all the functionality of the IPG must reside in the

claimed IPG application” on the device; “it is sufficient

that the IPG application provide an IPG in coordination

with [a] server.” App. 15a. Second, the panel held that

“adding or deleting channels” can be accomplished by

“subscribing and … unsubscribing” to channels in the

program guide, even though such channels appear in

the guide before they are “added” and remain there after

they are “deleted.” App. 17a-18a. The Federal Circuit

did so notwithstanding the fact that WhereverTV never

proposed these—or any other—constructions of either

limitation and instead successfully urged the district

court to not engage in claim construction and apply the

plain language of WhereverTV’s own patent.

Comcast petitioned for panel and en banc rehearing,

arguing that the panel erred by engaging in sua sponte

consideration of an issue that neither party raised and

10

that WhereverTV had deliberately waived. C.A. Pet. for

Reh’g 11. Rehearing was denied. App. 59a-60a.

REASONS FOR GRANTING THE PETITION

I. There is a Deep and Entrenched Circuit Split

The circuits are divided over whether they may address deliberately waived non-jurisdictional issues.

Four circuits hold that they lack the authority to address waived issues. All of the remaining circuits hold

that they may address waived issues—with two circuits,

including the Federal Circuit, holding that their discretion to do so is unbounded, and the remaining seven

holding that they may exercise discretion to address

waived issues only in limited circumstances.

The split is entrenched and widely acknowledged,

with one academic commentator describing the state of

the law as “a woefully undertheorized default presumption of party dominance, pockmarked by similarly undertheorized exceptions.” Scott Dodson, Party Subordinance in Federal Litigation, 83 Geo. Wash. L. Rev. 1, 5-6

(2014); see also, e.g., Robert J. Martineau, Considering

New Issues on Appeal: The General Rule and the Gorilla

Rule, 40 Vand. L. Rev. 1023, 1061 (1987) (“The only consistent feature of the current system is its inconsistency.”).

To be clear: All circuits will sometimes honor a

party’s deliberate waiver and decline to address a

waived issue. The question presented here, on which the

circuits are deeply divided, is whether and when courts

of appeals may choose to override a party’s waiver to decide an issue that the party itself abandoned.

1. The Third, Sixth, Tenth, and Eleventh Circuits

hold that they lack authority to address deliberately

waived issues.

11

The en banc Eleventh Circuit’s decision in United

States v. Campbell, 26 F.4th 860 (2022), exemplifies the

side of the split in which courts must give effect to a

party’s waiver. While the court divided over whether the

issue in that case had been deliberately waived or unintentionally forfeited, it was unanimous about the import

of that distinction: “Waiver directly implicates the

power of the parties to control the course of the litigation; if a party affirmatively and intentionally relinquishes an issue, then courts must respect that decision.” Id. at 872 (majority op.); see id. at 901 (Newsom,

J., and Jordan, J., dissenting) (“[T]here seems to be raging consensus about the governing principles here: If the

government waived the … issue by opting not to pursue

it … then it’s off the table.”).

In a thorough joint opinion, Judges Newsom and Jordan (joined by three other judges) explained that respect

for deliberate waiver derives from “the first principle of

first principles: In this country, we have an adversarial

justice system.” Id. at 893. This principle “has deep historical roots that predate this country’s founding.” Ibid.

“Adversarialism and the party-presentation principle

aren’t just deeply historical,” the joint opinion continued, “they’re also instrumental to—and protective of—

other core values of the Anglo-American judicial tradition,” including, among others, “fundamental fairness”

and the “separation of powers.” Id. at 895-97.

Three other circuits likewise hold that they lack authority to address deliberately waived issues.

In the Third Circuit, “[w]aived claims may not be

resurrected on appeal.” Barna v. Bd. of Sch. Dirs. of

Panther Valley Sch. Dist., 877 F.3d 136, 146 n.7 (3d Cir.

2017); see also, e.g., Robinson v. First State Cmty. Action

Agency, 920 F.3d 182, 187 (3d Cir. 2019) (similar).

12

The Sixth Circuit similarly holds that “[a] waiver

occurs when a party intentionally abandons a known

right” and “refuse[s] to consider this type of intentionally jettisoned argument.” Bannister v. Knox Cnty. Bd.

of Educ., 49 F.4th 1000, 1011-12 (6th Cir. 2022). The

Sixth Circuit’s language, however, is sometimes less

than crystal clear and may reserve some limited and undefined discretion to address waived issues. See, e.g.,

George v. Youngstown State Univ., 966 F.3d 446, 469

(6th Cir. 2020) (A party’s “intentional surrender typically precludes judicial consideration of a defense.” (emphasis added)).

Finally, in the Tenth Circuit “it is well-established

that we do not consider arguments an appellant intentionally disclaimed or abandoned.” Wyo-Ben Inc. v. Haaland, 63 F.4th 857, 870 (10th Cir. 2023). The Tenth Circuit’s respect for party presentation extends even to enforcing a limitations period against a party that waived

the issue, notwithstanding a “more-than-colorable question concerning whether [the limitations period] applies

at all.” Id. at 868; see id. at 869-70 (“Stated otherwise,

the parties’ litigation posture regarding the applicability of [the] limitations period to [the] claim provides the

conceptual baseline from which our analysis proceeds ….”).

2. In stark contrast, both the Federal Circuit and the

Fourth Circuit find no limit to their discretion to address deliberately waived issues.

As illustrated by the decision below, the Federal

Circuit holds that it “always possess[es] ‘the discretion

to decide when to deviate from th[e] general rule of

waiver.’” Ericsson Inc. v. TCL Commc’n Tech. Holdings

Ltd., 955 F.3d 1317, 1322 (Fed. Cir. 2020) (second alteration in original) (quoting Interactive Gift Express, Inc.

13

v. Compuserve, Inc., 256 F.3d 1323, 1344

(Fed. Cir. 2001)); see also, e.g., Ciena Corp., 958 F.3d at

1161 (“[I]t is a discretionary decision to forgive waivers

of non-jurisdictional challenges ….”).

The disregard for party presentation in the decision

below is emblematic of the Federal Circuit’s general approach. See, e.g., Egenera, Inc. v. Cisco Sys., Inc., 972

F.3d 1367, 1378 n.6 (Fed. Cir. 2020) (“[Appellee] contends that [appellant] waived any argument [on an issue]. Regardless, whether to apply the waiver rule is

discretionary. … To apply waiver would not serve judicial economy or promote fairness, and so we address the

merits.”). Despite Comcast raising this issue in its petition for en banc rehearing, the Federal Circuit is unwilling to reconsider its approach. App. 59a-60a.

The Fourth Circuit holds that, where an issue “‘implicate[s] important institutional interests of the court,’

[the court] retain[s] discretion to raise and consider it

sua sponte – even if waived.” Billard v. Charlotte Cath.

High Sch., 101 F.4th 316, 325 (4th Cir. 2024) (quoting

Eriline Co. v. Johnson, 440 F.3d 648, 654-55 (4th Cir.

2006)). But the Fourth Circuit has taken an expansive

approach to defining such “institutional interests.” It

has blessed sua sponte consideration of, for example,

waived res judicata arguments and various other arguments in habeas and in forma pauperis cases. See Eriline, 440 F.3d at 656 (“[B]oth habeas corpus and in

forma pauperis proceedings, like failure to prosecute,

abuse of process, and res judicata, implicate important

judicial and public concerns ….”). Whether the Fourth

Circuit’s claimed discretion to address waived issues is

just as broad as the Federal Circuit’s, or perhaps

slightly narrower, only underscores the confusion and

division among the circuits.

14

Judge Quattlebaum’s dissent from the panel opinion

in Sweeney v. Graham—a ruling this Court recently

summarily reversed—describes the Fourth Circuit’s approach to party presentation. No. 22-6513, 2025 WL

800452 (4th Cir. Mar. 13, 2025) (Quattlebaum, J., dissenting), rev’d sub nom. Clark v. Sweeney, No. 25-52,

2025 WL 3260170 (Nov. 24, 2025) (per curiam). Per

Judge Quattlebaum, “the majority’s special circumstances principle” for overriding party presentation “is

unworkably squishy”; “[t]he total absence of standards … is concerning” and “could be used to avoid the

settled requirements of the law and permit reaching

preferred outcomes.” Id. at *39. “This is no way to run a

railroad,” as “[a]ppellate review is not a game of moving

target.” Id. at *40. See also, e.g., Nat’l Ass’n of Immigr.

Judges v. Owen, 160 F.4th 100, 118 (4th Cir. 2025)

(Quattlebaum, J., dissenting from denial of reh’g en

banc) (“[T]he panel opinion shirks party presentation

principles—taking off its black robes to argue a case different from the one the [party] advanced.”), petition for

cert. pending sub nom. Margolin v. Nat’l Ass’n of Immigr. Judges, No. 25-767 (filed Dec. 23, 2025).

3. The remaining circuits articulate diverse standards (sometimes applied inconsistently) to describe the

limited circumstances in which they will address

waived issues.

The First Circuit does not appear to recognize a

strict distinction between deliberate waiver and inadvertent forfeiture and instead holds that “an appellate

court may, under exceptional circumstances, elect to

reach unpreserved issues in order to forestall a miscarriage of justice.” Sindi v. El-Moslimany, 896 F.3d 1, 28

(1st Cir. 2018). Among the “considerations” the court assesses in deciding whether to address unpreserved

15

issues are “whether the inadequately preserved arguments are purely legal, are amenable to resolution without additional factfinding, are susceptible to resolution

without causing undue prejudice, are highly convincing,

are capable of repetition, and implicate matters of significant public concern,” and “whether the failure to advance an argument was deliberate or inadvertent.” Ibid.

(citing Nat’l Ass’n of Soc. Workers v. Harwood, 69 F.3d

622, 627-28 (1st Cir. 1995)).

The Second Circuit claims “broad discretion to consider” waived issues on the ground that “waiver rules

are prudential and not jurisdictional.” Virgilio v. City of

New York, 407 F.3d 105, 116 (2d Cir. 2005). The court

‘“may rule on issues not raised in the district

court ... when the issues are solely legal ones not requiring additional factfinding.”’ Ibid. (quoting Westinghouse

Credit Corp. v. D’Urso, 371 F.3d 96, 103 (2d Cir. 2004)).

“[T]hat discretion may extend to factual determinations,” too, though the court is “‘seldom inclined to exercise this discretion’ when unresolved factual determinations exist.” Okor v. Ginsberg, 692 F. App’x 642, 643

(2d Cir. 2017) (quoting Paese v. Hartford Life & Accident

Ins. Co., 449 F.3d 435, 446 (2d Cir. 2006)).

The Fifth Circuit does not consistently distinguish

between waiver and forfeiture. To address either a

waived or forfeited issue, the court generally requires

“extraordinary circumstances,” which ‘“exist when the

issue involved is a pure question of law and a miscarriage of justice would result from [a] failure to consider

it.”’ AG Acceptance Corp. v. Veigel, 564 F.3d 695, 700

(5th Cir. 2009) (quoting N. Alamo Water Supply Corp. v.

City of San Juan, 90 F.3d 910, 916 (5th Cir. 1996)). The

court also sometimes reaches waived issues that “present purely legal questions that were briefed to the

16

district court … [i]n stewardship of judicial resources.”

Glass v. Paxton, 900 F.3d 233, 243 (5th Cir. 2018).

The Seventh Circuit holds that it “may, in [its] discretion, forgive waiver or forfeiture in a case that presents a pure question of statutory interpretation that

the parties have fully briefed on appeal.” Saxon v. Sw.

Airlines Co., 993 F.3d 492, 496 (7th Cir. 2021), aff’d, 596

U.S. 450 (2022). While the court noted that it “exercise[s] such discretion sparingly,” it has elected to do so

to address, for example, an “important and recurring

question of statutory interpretation.” Ibid.

The Eighth Circuit requires “exceptional circumstances” to address a waived issue. N. Bottling Co. v.

PepsiCo, Inc., 5 F.4th 917, 922 (8th Cir. 2021) (quoting

Platte Valley Bank v. Tetra Fin. Grp., LLC, 682 F.3d

1078, 1086 (8th Cir. 2012)). But, contrary to the courts

of appeals willing to address waived issues that are

purely legal, the Eighth Circuit has held that no such

exceptional circumstances exist to address a purely legal choice-of-law question that a party waived in the district court. See id. at 922-23.

The Ninth Circuit has—at times—recognized that

waiver of an issue “entirely precludes appellate review.”

United States v. Lopez, 4 F.4th 706, 719 n.3 (9th Cir.

2021). Yet—at other times, including en banc—the

court has addressed deliberately waived issues on the

grounds that it has “the authority and discretion to decide questions first raised in a petition for rehearing en

banc,” clarifying that “it is claims that are deemed

waived or forfeited, not arguments.” Brown v. Arizona,

82 F.4th 863, 873 (9th Cir. 2023) (en banc) (citations

omitted), cert. denied, 144 S. Ct. 1346 (2024); but see id.

at 898 (R. Nelson, J., dissenting) (“The majority and concurrence cite no case in which we have adopted an

17

argument that was affirmatively disclaimed by a party.

There is no precedent supporting what the majority is

actually doing here.”).

Finally, the D.C. Circuit claims “authority to remedy errors sua sponte in ‘exceptional circumstances’—

when they ‘seriously affect the fairness, integrity, or

public reputation of judicial proceedings.’” United States

v. Bombardier Corp., 380 F.3d 488, 497 (D.C. Cir. 2004)

(quoting United States v. TDC Mgmt. Corp., 288 F.3d

421, 425 (D.C. Cir. 2002)).

II. The Decision Below Warrants Review

1. “In our adversarial system of adjudication, we follow the principle of party presentation.” SinenengSmith, 590 U.S. at 375. “[W]e rely on the parties to

frame the issues for decision and assign to courts the

role of neutral arbiter of matters the parties present.”

Ibid. (quoting Greenlaw, 554 U.S. at 243). “[C]ourts are

essentially passive instruments of government”; they

“do not, or should not, sally forth each day looking for

wrongs to right.” Id. at 376 (quoting United States v.

Samuels, 808 F.2d 1298, 1301 (8th Cir. 1987) (Arnold,

J., concurring in denial of reh’g en banc)). “To put it

plainly, courts ‘call balls and strikes’: they don’t get a

turn at bat.” Clark, 2025 WL 3260170, at *1 (quoting

Lomax v. Ortiz-Marquez, 590 U.S. 595, 599 (2020)).

This Court has twice in the past six years held that

courts of appeals commit reversible error when they “depart [] drastically from the principle of party presentation.” Sineneng-Smith, 590 U.S. at 375. In SinenengSmith, this Court reversed the Ninth Circuit where it

“[e]lect[ed] not to address the party-presented controversy,” sua sponte sought amicus curiae briefing, and resolved the case on an issue that had not been raised by

18

the parties. Id. at 379-80. And in Clark v. Sweeney,

“[t]he Fourth Circuit transgressed the party-presentation principle by granting relief on a claim that [respondent] never asserted and [petitioner] never had the

chance to address.” 2025 WL 3260170, at *2. The party

“asserted ‘one, and only one,’ claim,” but “[i]nstead of

ruling on that claim, the Fourth Circuit devised a new

one.” Ibid. (citation omitted).

The party presentation principle applies with particular force in cases of deliberate waiver. In Day v.

McDonough, 547 U.S. 198 (2006), this Court held that a

district court has discretion to sua sponte raise a statute

of limitations defense to a habeas corpus petition that a

State had inadvertently forfeited. Id. at 209. But, in doing so, the Court noted that “we would count it an abuse

of discretion to override a State’s deliberate waiver of a

limitations defense.” Id. at 202; see also id. at 210 n.11

(“[S]hould a State intelligently choose to waive a statute

of limitations defense, a district court would not be at

liberty to disregard that choice.”).

In Wood v. Milyard, 566 U.S. 463 (2012), this Court

addressed deliberate waiver head on, again in the context of the timeliness of a habeas petition. There, “the

State twice informed the District Court that it ‘will not

challenge, but [is] not conceding’ the timeliness” issue.

Id. at 474. The district court accepted that waiver and

decided the case on the merits, but the Tenth Circuit

overrode the State’s waiver and found the petition time

barred. Id. at 467-68.

This Court reversed. The Court was clear that the

State’s “decision not to contest the timeliness of [the] petition did not stem from an ‘inadvertent error,’” as in

Day. Id. at 474. Rather, the State “express[ed] its clear

and accurate understanding of the timeliness issue” but

19

“deliberately steered the District Court away from the

question.” Ibid. Emphasizing the need for “[d]ue regard

for the trial court’s processes and time investment,” and

with concern that “the appellate court act[ed] not as a

court of review but as one of first view,” the Court held

that the court of appeals “abused its discretion when it

dismissed [the] petition as untimely.” Id. at 473-74. “[A]

federal court does not have carte blanche to depart from

the principle of party presentation basic to our adversary system.” Id. at 472.

There is no good reason to limit Day and Wood to the

habeas corpus or statute-of-limitations contexts: Courts

of appeals lack authority to override a party’s deliberate

waiver of any non-jurisdictional issue in all but the rarest of circumstances.

Requiring courts of appeals to respect deliberate

waiver emanates from “the first principle of first principles: In this country, we have an adversarial justice system.” Campbell, 26 F.4th at 893 (Newsom, J., and Jordan, J., dissenting). As Justice Scalia put it: “What

makes a system adversarial rather than inquisitorial is

… the presence of a judge who does not (as an inquisitor

does) conduct the factual and legal investigation himself, but instead decides on the basis of facts and arguments pro and con adduced by the parties.” McNeil v.

Wisconsin, 501 U.S. 171, 181 n.2 (1991).

A party’s decision to put an issue before a court is the

source of the court’s power to resolve it. It is the plaintiff—not the court—who “is ‘the master of the complaint,’” and who “gets to determine which substantive

claims to bring against which defendants.” Royal Canin

U.S.A., Inc. v. Wullschleger, 604 U.S. 22, 35 (2025)

(quoting Caterpillar Inc. v. Williams, 482 U.S. 386, 39899 (1987)). “[O]ur system ‘is designed around the

20

premise that [parties represented by competent counsel] know what is best for them, and are responsible for

advancing the facts and argument entitling them to relief.” Sineneng-Smith, 590 U.S. at 375-76 (second alteration in original) (quoting Castro v. United States, 540

U.S. 375, 386 (2003) (Scalia, J., concurring in part and

concurring in judgment)).

A party’s decision to intentionally withdraw an issue

from a court of appeals’ cognizance in turn should deprive the court of authority to address it. When a party

deliberately waives an issue, they eliminate adversity

with respect to that issue. Just as when parties seek voluntary dismissal, “they consent[] to the judgment

against them and disavow[] any right to relief” on that

ground. Microsoft Corp. v. Baker, 582 U.S. 23, 44 (2017)

(Thomas, J., concurring in judgment). “The parties thus

[a]re no longer adverse to each other” with respect to the

waived issue “and the Court of Appeals could not ‘affect

the[ir] rights’ in any legally cognizable manner.” Id. at

44-45 (quoting Lewis v. Cont’l Bank Corp., 494 U.S. 472,

477 (1990)). The court, as a “passive instrument[] of government,” has no ability to revive adversarial presentation sua sponte, and thus cannot override a party’s decision to waive an issue. Sineneng-Smith, 590 U.S. at 376

(citation omitted).

It is particularly inappropriate for a court to substitute its view of the party’s best interests for the party’s

own. There are many reasons why parties may waive

winning issues, reasons which may be—and often

should be—unknown to the court. Parties may seek to

invite (or avoid) precedent on specific issues of broader

significance. See, e.g., Certain Underwriters at Lloyds

London v. Perraud, 623 F. App’x 628, 635 (5th Cir. 2015)

(King, J., dissenting) (hypothesizing that a party’s

21

waiver sought “to force a ruling ... which will undoubtedly impact … future cases”). They may need to balance

multiple competing issues in a single case—as often

happens in patent cases, where securing broad claim

constructions may increase the risk that a patent will be

found invalid. Cf. Amgen Inc. v. Sanofi, 598 U.S. 594,

613 (2023) (“[T]he more a party claims, … the more it

must enable.”). They may fear that success in the courtroom will harm their standing with customers or the

public. See Claire Fahy, Disney Backs Down from Effort

to Use Disney+ Agreement to Block Lawsuit, N.Y. Times

(Aug. 20, 2024). Or they may simply think it is the right

thing to do. See Day, 547 U.S. at 217-18 (Scalia, J., dissenting) (“There are many reasons why the State may

wish to disregard the statute of limitations, including

the simple belief that it would be unfair to impose the

limitations defense on a particular defendant.”). Whatever the reason, what matters is this: It is for the parties

and not the court to decide which issues to raise and

which to waive. Courts in our adversarial system must

respect that decision.

Respect for a party’s deliberate waiver finds support

in the history and constitutional structure of our judicial

system. As Judges Newsom and Jordan noted, “[a]dversarialism has deep historical roots that predate this

country’s founding.” Campbell, 26 F.4th at 893 (Newsom, J., and Jordan, J., dissenting). The “limits placed

on federal judges by the adversarial system comported

with the views of those who drafted the Constitution.”

Ibid. (quoting Judith Resnik, Managerial Judges, 96

Harv. L. Rev. 374, 381 (1982)).

Consistent with this history, Article III limits the

power of the federal courts “to questions presented in an

adversary context.” Flast v. Cohen, 392 U.S. 83, 95

22

(1968); see Muskrat v. United States, 219 U.S. 346, 357

(1911) (Article III “implies the existence of present or

possible adverse parties, whose contentions are submitted to the court for adjudication.” (citation omitted)).

“[A]llowing unelected and unaccountable federal judges

‘to transgress the limits of the parties’ arguments gives

them the power to set their own agendas—a power normally reserved for the political branches.’” Campbell, 26

F.4th at 895-96 (Newsom, J., and Jordan, J., dissenting)

(quoting Amanda Frost, The Limits of Advocacy, 59

Duke L.J. 447, 481 (2009)).

Moreover, the “opportunity to respond” is “fundamental to due process.” Nelson v. Adams USA, Inc., 529

U.S. 460, 465-68 (2000). A court of appeals’ sua sponte

decision to override a party’s deliberate waiver may

deny the parties “adequate notice of the critical issue

that the judge was actually debating.” Lankford v.

Idaho, 500 U.S. 110, 120 (1991).

Respect for deliberate waiver also advances “other

core values of the Anglo-American judicial tradition.”

Campbell, 26 F.4th at 895 (Newsom, J., and Jordan, J.,

dissenting). “[O]ur legal tradition regards the adversary

process as the best means of ascertaining truth and

minimizing the risk of error.” Ibid. (quoting Mackey v.

Montrym, 443 U.S. 1, 13 (1979)); see also Trump v. Illinois, 2025 WL 3715211, at *9 (Gorsuch, J., dissenting)

(disregarding waiver deprives questions of “the full airing they so clearly deserve”). “If a court engages in what

may be perceived as the bidding of one party by raising

claims or defenses on its behalf,” or disregarding its decision to waive issues, “the court may cease to appear as

a neutral arbiter.” Campbell, 26 F.4th at 896 (Newsom,

J., and Jordan, J., dissenting) (quoting Burgess v.

United States, 874 F.3d 1292, 1300 (11th Cir. 2017)).

23

Respecting deliberate waiver also ensures “[d]ue regard

for the trial court’s processes and time investment.”

Wood, 566 U.S. at 473. “Finally, adherence to the adversarial method and the party-presentation principle ‘promotes litigant and societal acceptance of decisions rendered by the courts.’” Campbell, 26 F.4th at 896 (Newsom, J., and Jordan, J., dissenting) (citation omitted).

To be sure, there may be a narrow set of issues or

circumstances where a court of appeals does not err by

overriding a party’s deliberate waiver. For example, issues implicating subject-matter jurisdiction generally

are “not subject to waiver.” Hamer v. Neighborhood

Hous. Servs. of Chi., 583 U.S. 17, 20 (2017). There could

be unusual situations in which honoring a party’s deliberate waiver would compromise inviolable constitutional commands. Cf. Commodity Futures Trading

Comm’n v. Schor, 478 U.S. 833, 851 (1986) (“When these

Article III limitations are at issue, notions of consent

and waiver cannot be dispositive ….”). And courts may

in appropriate circumstances consider issues that were

inadvertently forfeited, not deliberately waived. But the

possibility of such exceptions does not detract from the

general principle of party presentation—i.e., that the

courts of appeals lack authority to address a non-jurisdictional issue that a party deliberately waives.

2. A straightforward application of this rule compels

reversal of the Federal Circuit’s decision in this case.

In the decision subject to this appeal, the parties disputed and asked the district court to address only one of

the “two elements of a simple patent case”: “whether infringement occurred.” Markman, 517 U.S. at 384.

WhereverTV repeatedly and deliberately waived the

other element—claim construction—by telling both the

district court and the court of appeals not to construe

24

the relevant claim language and to measure infringement by the plain text of WhereverTV’s own patent. See

pp. 5-8, supra. Had the Federal Circuit addressed the

sole question WhereverTV put before it—whether the

district court erred in ruling that the evidence did not

suffice to show infringement—Comcast would have prevailed and the case would have been over.

Instead, the Federal Circuit—consistent with circuit

precedent allowing it to freely consider waived issues—

overrode WhereverTV’s repeated and deliberate waiver

of claim construction. The court went so far as to hold

that “[t]he district court legally erred” by not overriding

WhereverTV’s waiver and addressing only the partypresented controversy. App. 12a.

The panel suggested that O2 Micro, 521 F.3d at 1351,

requires district courts to resolve latent claim construction disputes, even when no party asks for claim construction and the issue has been deliberately waived.

App. 12a. But that cannot be for the simple reason that

the Federal Circuit cannot unilaterally abrogate the

party presentation principle for claim construction—or

any other issue. Indeed, the Federal Circuit has elsewhere made clear that claim construction, just like any

other issue, can be waived. See Kaufman v. Microsoft

Corp., 34 F.4th 1360, 1369 (Fed. Cir. 2022) (“‘[A] party

must ‘sufficiently request further construction of the relevant limitation’ to ‘raise an actual dispute.’” (quoting

LifeNetHealth v. LifeCell Corp., 837 F.3d 1316, 1322

(Fed. Cir. 2016))). The problem, however, is that the

court believes it may override such a waiver in any particular case for any reason (or none at all)—as it did

here.

Worse still, the Federal Circuit went on to decide the

waived issue itself. Unsurprisingly, the panel’s sua

25

sponte claim constructions make little sense. According

to the Federal Circuit, channels can be “added” to the

program guide even if they already appear in the guide

beforehand and can be “deleted” from the guide even if

they continue to remain in the guide afterwards. App.

17a-18a. And, again according to the Federal Circuit, an

“interactive program guide application installed on the

device that provides a user-configurable interactive program guide” “need not provide all the functionality for

operation of the [interactive program guide].” App. 14a15a.

Had the Federal Circuit applied the plain language

of WhereverTV’s patent—as both parties urged—it

would have had no choice but to affirm the district court.

As the district court correctly recognized, the evidence

showed that Comcast’s X1 system prohibited adding or

deleting channels and lacked an interactive program

guide application installed on the set-top box that provided an interactive program guide. App. 36a, 40a. Instead, the parties must now proceed to a potential second trial on remand. The decision below illustrates exactly why “the adversary process”—not sua sponte consideration of waived issues—“[i]s the best means of ascertaining truth and minimizing the risk of error.”

Mackey, 443 U.S. at 13.

III. The Question Presented is Important and Merits Review

in this Case

1. The question of whether a court of appeals may

override a party’s deliberate waiver of non-jurisdictional

issues or must instead respect party presentation is of

obvious legal and practical significance. Cf. Clark, 2025

WL 3260170, at *1; Sineneng-Smith, 590 U.S. at 371;

Wood, 566 U.S. at 463. Under the Federal Circuit’s

26

regime—and in any of the nine courts of appeals where

the court may override a waiver—the court may decide,

if it so chooses, issues the parties have deliberately

taken off the table. Parties must accept the possibility

that the court of appeals will transform their appeals

sua sponte, perhaps without notice or opportunity to respond, as occurred here. And district courts risk reversal when they address and correctly resolve only the

party-presented controversy.

The Federal Circuit’s approach, as illustrated by the

decision below, alone merits this Court’s attention. In

arrogating to itself the right to override party presentation—and by holding that district courts sometimes

must override a party’s deliberate waiver of claim construction—the Federal Circuit injected profound uncertainty into every patent case where a patentee asks that

infringement be measured by the plain language of its

own patent.2 District courts must now sally forth to

identify and resolve claim construction issues not presented by the parties on pain of reversal. The waste of

court and party resources the decision below invites in

patent cases nationwide alone justifies this Court’s intervention.

But the significance of the question presented extends far beyond patent cases. Any waived non-jurisdictional issue is always up for grabs on appeal in two

2 Patentees frequently forego claim construction entirely, relying

on the patent as written, or else seek constructions of only a subset

of claim terms—indeed, some courts impose limits on the number

of claims that may be construed. See generally Timothy A. Richard,

The Timing of Claim Construction: An Analysis of Claim Construction Procedure and a Proposed Rule to Ensure Cost Effective and

Timely Relief in Patent Infringement Cases, 33 Cath. U. J. L. & Tech

85, 104-11 (2025).

circuits, and sometimes up for grabs in seven more. The

question presented, moreover, raises significant structural and constitutional concerns. “This Court … has a

significant interest in supervising the administration of

the judicial system” particularly in matters “relate[d] to

the integrity of judicial processes.” Hollingsworth v.

Perry, 558 U.S. 183, 196 (2010). Our adversarial system

and Article III limit the federal courts to addressing

genuine disputes selected and presented by the parties.

The decision below flouts those limits, and the vast circuit split creates different systems of judicial review

across the geographic circuits—and still another for patent cases.

There is no reason to await further percolation.

Every court of appeals has addressed this issue. The

courts of appeals have long been deeply divided and remain so after Sineneng-Smith. The Federal Circuit confirmed that its extreme position—directly at odds with

at least the en banc Eleventh Circuit’s and several others’—is here to stay by denying Comcast’s petition for

rehearing en banc. Numerous scholars have identified

this issue and called for this Court’s review.3 This

Court’s intervention is needed now.

See, e.g., Rory Little, Party Presentation: A Mysterious New

Rule?, SCOTUSblog (Dec. 17, 2025) (“I hope and expect the justices

to say more, and I’ll wager not unanimously, on the topic soon.”);

ongoing conflict over party presentation in the lower courts”),

that there are no clear rules guiding courts considering whether to

raise new issues sua sponte.”); Joan E. Steinman, Appellate Courts

2. This case is an ideal vehicle for deciding the question presented.

There is no concern about preservation or presentation. The Federal Circuit, in its unpublished opinion,4

sua sponte raised and resolved an issue neither party

had presented and WhereverTV had deliberately

waived. Had WhereverTV’s waiver been respected, the

court would have affirmed the district court’s ruling of

non-infringement and affirmed its judgment. Comcast

raised this issue at the first available juncture, in a petition for rehearing and rehearing en banc, which was

denied. See C.A. Pet. for Reh’g 11; App. 59a-60a.

WhereverTV’s waiver was explicit, deliberate, and

repeated. There can be no possible argument that this

case involves inadvertent forfeiture. Cf. Campbell, 26

F.4th at 877 (finding an issue forfeited rather than

waived). WhereverTV repeatedly disclaimed any need

for construction of the disputed claim terms and insisted

on proceeding with the claim’s plain language. The district court acknowledged and respected that waiver. The

Federal Circuit did not.

L. Rev. 1521, 1619 (2012) (“[T]he Supreme Court can and should do

better than it has done in … guiding federal [appellate courts] in

their exercises of discretion to hear or not to hear new issues.”);

Frost, The Limits of Advocacy, supra, 59 Duke L.J. at 463 (“[J]udges

have not articulated a clear set of conditions that lead them to deviate from their typical practice of letting the parties frame the dispute.”).

4 “[T]he fact that the Court of Appeals’ order under challenge here

is unpublished carries no weight in our decision to review the case.”

Comm’r v. McCoy, 484 U.S. 3, 7 (1987).

29

Although this petition arises from a patent case, it

provides the Court with a clean vehicle to address a pure

procedural question of broad significance. And it avoids

any potential complexities that might result from a

party’s waiver of questions of constitutional or statutory

interpretation. See Schor, 478 U.S. at 851 (addressing

waiver of constitutional issues); U.S. Nat’l Bank v. Indep. Ins. Agents of Am., Inc., 508 U.S. 439, 448 (1993)

(“We need not decide whether the Court of Appeals had,

as it concluded, a ‘duty’ to address the status of” a relevant statute); cf. Teva, 574 U.S. at 331 (“[T]his Court

has never previously compared patent claim construction in any here relevant way to statutory construction.”).

Nor is the case’s interlocutory posture any reason to

deny review of a dispositive issue. Had the Federal Circuit properly respected party presentation and honored

WhereverTV’s deliberate waiver, it would have affirmed

the district court, and this case would have been over.

Instead, the Federal Circuit’s decision means that the

parties must proceed towards a costly and burdensome

potential retrial on remand—and must do so under the

Federal Circuit’s improper and misguided sua sponte

claim constructions. That is a reason to grant rather

than deny review. Cf. Clark, 2025 WL 3260170, at *1

(reviewing the court of appeals’ grant of a new trial).

The decision below conflicts with this Court’s recent

and repeated admonitions to courts of appeals directing

them to respect rather than override party presentation.

It deepens an acknowledged split among the courts of

appeals on an important issue. And it imposes a rule

that disrupts trial and appellate practice nationwide.

The Court should grant the petition.

30

CONCLUSION

The petition for a writ of certiorari should be granted.

The Court may wish to consider summary reversal.

Respectfully submitted.

Before TARANTO, STOLL, and STARK, Circuit Judges.

STOLL, Circuit Judge.

WhereverTV, Inc. sued Comcast Cable Communications, LLC for patent infringement in the United

States District Court for the Middle District of Florida,

and the case proceeded to a jury trial on infringement

of claim 1 of U.S. Patent No. 8,656,431. After the

close of evidence but prior to a jury verdict, however,

the district court granted Comcast’s motion for judgment of noninfringement as a matter of law under

Rule 50(a) of the Federal Rules of Civil Procedure.

WhereverTV appeals the district court’s JMOL, alleging

that it rests on erroneous constructions of two terms

in claim 1. As an alternative ground for affirmance,

Comcast argues that it is entitled to JMOL based on

what it asserts is the correct interpretation of a

separate claim term, and it cross-appeals the district

court’s determination that claim 1 is not indefinite

under 35 U.S.C. § 112. Because we agree with

WhereverTV that the district court erred in its claim

construction, and we reject Comcast’s alternative

grounds for affirmance as well as its argument that

claim 1 is indefinite, we vacate the district court’s

JMOL of noninfringement and remand for proceedings

consistent with this opinion.

BACKGROUND

The ’431 patent discloses “[a] system and device . . .

that employs a global interactive program guide [(‘IPG’)]

to receive, access, manage, and view digital entertainment services such as live television, television on

demand, and pre-recorded video and audio programming from one or more content sources, via an

internet-enabled device, anywhere in the world.” U.S.

Patent No. 8,656,431 Abstract. The content sources

3a

include not only cable operators but also independent

content providers. The ’431 patent states that its “goal

is to shift the control of content availability,

organization, and access from MSO’s [(i.e., multisystem operators)], which is today’s cable television

model, to a new user-centric model where the user can

choose whether or not to purchase content from a

content consolidator or directly from independent

content providers.” Id. at col. 6 ll. 39–44. The specification explains that, at the time of the invention, there

was “no application or interface that [would] allow[] a

user to manage multiple subscriptions from multiple

content owners in an easy to use format.” Id. at col. 2

ll. 36–38.

As explained below, the district court relied on

patent Figures 4 and 8 in construing claim 1 at JMOL.

Figure 4 (reproduced below) is a graphical representation of the functions of an IPG that is “comprised of

eight Core Application Functions 300 and fifteen Core

Application Features 320, which may be used in whole,

or in parts, to present content to the user.” Id. at col. 11

ll. 17–21; see also id. at col. 11 l. 22–col. 13 l. 7. Figure

8 is a flow chart that illustrates the logic undertaken

by a user to add new content to the IPG. See id. at col.

15 l. 13–col. 16 l. 7.

4a

Id. Fig. 4.

The sole asserted claim, independent claim 1, reads:

1. A content manager device comprising:

a server resident on a network containing

descriptive program data about video content

available from one or more multiple cable

system operators (MSOs) and one or more

non-MSOs;

a device capable of establishing and maintaining a connection with the network via a

communications link; and

an interactive program guide application

installed on the device that provides userconfigurable interactive program guide (IPG)

listing at least one channel of video content

5a

available from each of the one or more MSOs

and each of the one or more nonMSOs and

descriptive program data from the server for

the video content available on each of the

channels, wherein each of the channels is

selectable for receiving only or virtually

entirely streaming video programming from

its respective MSO or non-MSO source via

the communications link and the network;

wherein the server is distinct from at least one

of the one or more MSOs and one or more nonMSOs, and wherein the application allows for

the IPG to be configured by a user with respect

to adding or deleting channels from any of

the one or more MSOs or the one or more

non-MSOs.

Id. at col. 16 ll. 32–54 (emphases added to emphasize

limitations at issue).

WhereverTV accused Comcast’s entertainment platform known as the Xfinity X1, which allows users to

access video content from both their cable provider and

streaming providers through a cloud-based system, of

infringing claim 1 of the ’431 patent. The X1 system

includes the XRE receiver, which is an application

located on the X1 set-top box (or “STB”) device, and the

cloud-based XRE server. Comcast’s documentation

illustrates the division of its system:

6a

J.A. 15921. The same document describes the division

of the XRE receiver and server:

 XRE Receiver running on device is thin

client

 Is a light weight renderer

 Accepts and forwards user input

 Application logic does not execute here

 Does not have to be updated to update

user experience and features

 XRE Server runs in the cloud

 Integrates with the back end services

 Interprets user input (as passed from

XRE Receiver)

 Executes all of the application business

logic

 Generates rendering instructions for

the XRE Receiver

J.A. 15922.

7a

At the claim construction stage before the district

court, the parties disputed seven terms: (1) “multiple

cable system operators (MSOs)”; (2) “non-MSOs”;

(3) “wherein the server is distinct from at least one of

the one or more MSOs and one or more non-MSOs”;

(4) “only or virtually entirely streaming video programming”; (5) “wherein each of the channels is

selectable for receiving only or virtually entirely

streaming video programming”; (6) “interactive program guide”; and (7) “adding or deleting channels from

any of the one or more MSOs or the one or more

nonMSOs.” See WhereverTV, Inc. v. Comcast Cable

Commc’ns, LLC, No. 2:18-cv-529-FTM-NPM, 2020 WL

13823257, at *3 (M.D. Fla. Nov. 13, 2020) (“Claim

Construction Order”). The district court construed

“multiple cable system operators (MSOs)” to mean “a

cable, satellite, or Internet television content consolidator that receives and then broadcasts channels of

video content,” and “non-MSOs” to mean “a video

content provider that does not act like an MSO

because it does not receive and then broadcast

channels of video content.” Id. As for the remainder of

the disputed terms, the district court determined that

“[n]o further construction is necessary.” Id.

Comcast also contended that the term “only or

virtually entirely streaming video programming” was

indefinite under 35 U.S.C. § 112. But the district court

determined that “these words can be understood by

those skilled in the art, particularly since Comcast

itself was able to propose a construction for [‘wherein

each of the channels is selectable for receiving only or

virtually entirely streaming video programming,’]

which contains the same language.” Id. Specifically,

Comcast proposed interpreting “wherein each of the

channels is selectable for receiving only or virtually

entirely streaming video programming” as: “wherein

8a

each of the channels is configured such that, in

immediate response to selection of its assigned channel

number, and without further searching, video programming is only or virtually entirely transmitted

over the Internet . . . and made available for viewing

while the transmission is occurring.” Id. The district

court thus determined that Comcast had not met its

burden to show that the term was indefinite by clear

and convincing evidence.

At the summary judgment stage, the district court

recognized that the parties still disputed the scope

of the limitation “wherein the server is distinct from

at least one of the one or more MSOs and one or

more non-MSOs.” The district court explained that

“[WhereverTV] conceptualize[d] such distinctness in

terms of the tasks and processes of the server and the

MSO and non-MSO, while Comcast conceptualize[d]

the distinctness in terms of a business entity’s ownership or control of the MSO and server.” J.A. 11460.

To resolve this dispute, the district court ordered a

supplementary evidentiary hearing that included

the presentation of exhibits and expert testimony

concerning the construction of the limitation.

After considering intrinsic and extrinsic evidence,

the district court determined that “the meaning of

‘distinct from,’ in context, is best read to pertain to

functional differences between the server and the

MSO(s) and nonMSO(s), rather than differences

with respect to control.” J.A. 11467–68. Based on this

determination, the court construed the term to mean

“wherein the server is functionally distinct from at

least one of the one or more MSOs and one or more

non-MSOs.” J.A. 11468.

The case proceeded to a jury trial. At the close

of WhereverTV’s case-in-chief, Comcast moved for a

9a

directed verdict of noninfringement on the “adding or

deleting” limitation (“wherein the application allows

for the IPG to be configured by a user with respect to

adding or deleting channels from any of the one or

more MSOs or the one or more non-MSOs”), as well as

the “IPG application” limitation (“an interactive

program guide application installed on the device that

provides user-configurable interactive program guide

(IPG)”). The district court granted JMOL after the

close of evidence.

In its written order, the district court first addressed

the adding or deleting limitation and reaffirmed its

plain and ordinary meaning construction of this term.

The district court then determined that “[a]t no point

during trial did [WhereverTV] introduce evidence that

an X1 user could subscribe to a channel that was not

already offered on the accused X1’s IPG, thereby

increasing the number of channels offered on the IPG.”

WhereverTV, Inc. v. Comcast Cable Commc’ns, LLC,

No. 2:18-cv-529-WFJ-NPM, 2023 WL 3819123, at *5

(M.D. Fla. June 5, 2023) (“JMOL Order”). “Nor did

[WhereverTV] introduce any evidence that a user who

unsubscribed from a particular app—such as Netflix—

could remove that app from the X1’s IPG entirely such

that . . . the app would not be displayed on the IPG.”

Id. The district court faulted WhereverTV for “encouraging the jury to accept that subscribing is adding and

unsubscribing is deleting,” which the court viewed as

“a departure from the plain and ordinary meaning

of these terms.” Id. The district court held that

“[WhereverTV] may not assert literal infringement

based on the theory that unsubscribing from an

app . . . is conceptually similar to deleting that app

simply because both actions create impediments for

the user who wants to watch content offered by the

app.” Id. at *6. The district court further explained that

10a

“the rigidity of the X1’s IPG display and the

immutability of the channel listings provided by

Comcast,” as testified to by both parties’ witnesses, “is

in no way identical to the customizable and restrictionfree invention described in the [’]431 Patent’s specification.” Id. at *7. The district court also determined

that, “[w]hile the [’]431 Patent allows users to increase

the number of channels available to them—true to

the plain and ordinary meaning of ‘adding’—the X1

only allows users to log in and out of channels that

Comcast, and only Comcast, chose irrevocably to

emplace on the IPG.” Id.

The district court next addressed the IPG application limitation, again noting that it was maintaining

a plain and ordinary meaning construction despite

recognizing that the “term’s plain and ordinary

meaning is not readily apparent.” Id. The district court

then held that there was “uncontested evidence” that

the IPG application is not installed on the accused

device because the XRE guide application is on the

server and not the STB. Id. at *8. The district court

also found that the XRE guide application provides the

“brains” for the IPG. Id. The district court further

determined that it was “undisputed that the cloudbased XRE server, and not the XRE receiver, provides

‘the data necessary for the . . . IPG.’” Id. at *9 (omission

in original) (emphasis removed) (citation omitted). As

to WhereverTV’s argument that the XRE receiver on

the STB is the IPG application, the district court

determined that “the [’]431 Patent’s specification

does not support this conclusion,” in view of Figures 4

and 8. Id. at *8. The district court, in considering

WhereverTV’s expert testimony that the XRE receiver

is a “thin client” capable of rendering and signaling,

found that this did not show that an IPG application

11a

was installed on the STB. Id. at *8–9 (citation

omitted).

WhereverTV appeals and Comcast cross-appeals.

We have jurisdiction under 28 U.S.C. § 1295(a)(1).

DISCUSSION

On appeal, WhereverTV primarily argues that the

district court’s JMOL rests on erroneous constructions

of both the “IPG application” and “adding or deleting”

limitations. For its part, Comcast presents two issues.

First, Comcast introduces an alternative ground to

affirm the district court’s JMOL, contending that the

district court misconstrued the limitation “wherein the

server is distinct from at least one of the one or more

MSOs and one or more nonMSOs.” Finally, Comcast

cross-appeals the district court’s determination that

the limitation “selectable for receiving only or virtually

entirely streaming video programming” is not indefinite.

We review a district court’s grant of JMOL under the

standard of the regional circuit, Cyntec Co., Ltd. v.

Chilisin Elecs. Corp., 84 F.4th 979, 984 (Fed. Cir. 2023),

here the Eleventh Circuit, which reviews the grant of

JMOL de novo. Pickett v. Tyson Fresh Meats, Inc., 420

F.3d 1272, 1278 (11th Cir. 2005). Substantive patent

law issues are reviewed under the law of our own

circuit. Accenture Glob. Servs., GmbH v. Guidewire

Software, Inc., 728 F.3d 1336, 1340 (Fed. Cir. 2013). We

review claim construction based on intrinsic evidence

de novo and review factual findings about extrinsic

evidence for clear error. SpeedTrack, Inc. v. Amazon.com,

998 F.3d 1373, 1378 (Fed. Cir. 2021) (citing Teva

Pharms. USA, Inc. v. Sandoz, Inc., 574 U.S. 318,

331–32 (2015)). “Whether a claim complies with the

definiteness requirement . . . is a matter of claim

12a

construction.” Noah Sys., Inc. v. Intuit Inc., 675 F.3d

1302, 1311 (Fed. Cir. 2012).

We review in turn each issue raised by the parties.

I

WhereverTV contends that the district court erred

in holding, as a matter of law, that Comcast’s accused

product does not satisfy claim 1’s IPG application

limitation—an “interactive program guide application

installed on the device that provides user-configurable

interactive program guide (IPG).” We agree.

The district court legally erred by not construing this

limitation using the claim construction framework set

forth in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir.

2005). While the district court held that the plain and

ordinary meaning of the limitation applies, it also

stated that the plain and ordinary meaning is “not

readily apparent” and never clarified what it viewed as

the plain and ordinary meaning. JMOL Order, at *7.

Moreover, the parties clearly disputed the scope of

this term. In O2 Micro International Ltd. v. Beyond

Innovation Technology Co., we held that where the

parties dispute the scope of a claim limitation, the

district court is to construe the claims at least to

the extent necessary to resolve the dispute. 521 F.3d

1351, 1360 (Fed. Cir. 2008); see also id. at 1361

(“A determination that a claim term . . . has [a] ‘plain

and ordinary meaning’ may be inadequate . . . when

reliance on a term’s ‘ordinary’ meaning does not

resolve the parties’ dispute,” in which case “claim

construction requires the court to determine what

claim scope is appropriate in the context of the

patents-in-suit.”). We have also held that a district

court should not construe claims in light of an accused

product and should instead analyze the claim lan-

13a

guage, specification, and prosecution history, if relevant. See Wilson Sporting Goods Co. v. Hillerich &

Bradsby Co., 442 F.3d 1322, 1330 (Fed. Cir. 2006)

(“[C]laims may not be construed with reference to the

accused device.” (citation omitted)).

The district court’s JMOL cannot stand under

the proper construction of this limitation. We begin

with the claim language: “interactive program guide

application installed on the device that provides userconfigurable interactive program guide (IPG).” See

Phillips, 415 F.3d at 1314 (emphasizing importance of

claim language). The parties primarily dispute what it

means for the IPG application to “provide” a userconfigurable IPG. Comcast asserts that the limitation’s use of the word “provides” means that the

claimed IPG application alone must provide the

functionality of the user-configurable IPG. See CrossAppellant’s Br. 45–46, 56. But the term “provides” is

commonly understood to have a broader meaning,1 and

neither party suggests that it is a technical term with

a more limited meaning in the relevant field of art.

Used alone, “provides” does not require that the IPG

application do all the work to make the IPG operable.

This understanding of “provides” is also consistent

with the entire claim limitation, which requires an

“interactive program guide application installed on

the device that provides user-configurable interactive

program guide (IPG) listing at least one channel of

video content available from each of the one or more

MSOs and each of the one or more non-MSOs and

descriptive program data from the server.” Claim 1

itself contemplates that the server provides descrip1

14a

tive program data. The claim is also open-ended, using

the transitional phrase “comprising,” which allows for

the use of an additional IPG application in the server.

AFG Indus., Inc. v. Cardinal IG Co., Inc., 239 F.3d 1239,

1244–45 (Fed. Cir. 2001) (“When a claim uses an

‘open’ transition phrase, its scope may cover devices

that employ additional, unrecited elements. We have

consistently held that the word ‘comprising’ is an open

transition phrase.” (citation omitted)). In addition, as

discussed in more detail below, claim 1 recites that the

IPG application “allows for the IPG to be configured by

a user with respect to adding or deleting channels.”

The broad language “allows for” is consistent with the

view that the IPG application need not provide all the

functionality for operation of the IPG.

Turning to the specification, we conclude that the

district court improperly read additional requirements

into claim 1 based on the embodiments shown in

Figures 4 and 8 of the ’431 patent, including that

the IPG application “‘procures digital rights via

stored profile,’ ‘locates and authenticates’ new content

sources, and ‘downloads and synchronizes content

metadata from new content sources.’” JMOL Order, at

*8 (citation omitted). In particular, the district court

held that the accused device’s XRE receiver is not an

IPG application as required by the claims because it

does not “offer[] any of the functions or features

illustrated in Figures 4 or 8.” Id. But none of these

functions or features are recited in claim 1, let alone

recited as being performed by the IPG application.

Moreover, the specification does not define an IPG

application as limited to the embodiments in Figures

4 and 8. Nor does it disclaim placing some of the

functionality in Figures 4 and 8 in a server and other

functionality in a receiver. We are not inclined to read

the functionality from Figures 4 and 8 into the claim

15a

in such a limiting manner absent lexicography or

express disclaimer. See GE Lighting Sols., LLC v.

AgiLight, Inc., 750 F.3d 1304, 1308–09 (Fed. Cir. 2014)

(“[C]laim terms must be construed in light of the

specification and prosecution history . . . . However, the

specification and prosecution history only compel

departure from the plain meaning in two instances:

lexicography and disavowal. . . . [Here,] while the

specification[] only disclose[s] a single embodiment of

[the claimed term] in Figure 6, [it] do[es] not disavow

or disclaim the plain meaning of [the term] or otherwise limit it to that embodiment.” (citation omitted)).

Based on the claim language and the specification,2

we agree with WhereverTV’s interpretation that

the language “interactive program guide application

installed on the device that provides user-configurable

interactive program guide (IPG)” does not require that

all the functionality of the IPG must reside in the

claimed IPG application. In other words, it is sufficient

that the IPG application provide an IPG in coordination with the server.

II

The parties also disputed the meaning of claim 1’s

adding or deleting channels limitation—i.e., “wherein

the application allows for the IPG to be configured by

a user with respect to adding or deleting channels.”

WhereverTV asserts that channels can be added by

2

On appeal, neither party relies on the prosecution history of

the ’431 patent for this term, and the only extrinsic evidence cited

that is unconnected to a comparison between the claim language

and the accused product is the uncontested definition of

“application” from WhereverTV: a “program designed to assist in

the performance of a specific task, such as word processing,

accounting, or inventory management.” Appellant’s Br. 20 (citing

J.A. 15665).

16a

subscribing and deleted by unsubscribing, whereas

Comcast asserts that adding a channel is limited to

making the channel appear on the IPG user interface

and deleting a channel is limited to making the

channel no longer appear on the IPG user interface.

The district court purported to use the plain and

ordinary meaning of the limitation,3 which in its view

excluded the broader understanding that WhereverTV

asserted. See JMOL Order, at *4–5. We adopt

WhereverTV’s broader construction.

Again, we begin with the claim language. Claim 1

requires listing at least one MSO channel and at least

one non-MSO channel, wherein “each of the channels

is selectable” and “the application allows for the IPG

to be configured by a user with respect to adding or

deleting channels from any of the one or more MSOs

or the one or more non-MSOs.” The claim language

does not say “adding or deleting channels” to or from

the IPG user interface.4 Rather the claim recites

adding or deleting channels from the MSOs or nonMSOs. In addition, the claim focuses on channels that

3

The district court’s plain and ordinary meaning analysis

focused on dictionary definitions, but extrinsic evidence cannot

take precedence over the intrinsic record in a court’s claim

construction analysis. See Phillips, 415 F.3d at 1317 (“[W]hile

extrinsic evidence can shed useful light on the relevant art, we

have explained that it is less significant than the intrinsic record

in determining the legally operative meaning of claim language.”

(quotation marks and citation omitted)).

4

Comcast’s vague contention that WhereverTV should be

estopped from making this argument on appeal is underdeveloped and unpersuasive. Accordingly, we do not address this

contention further. See, e.g., In re Killian, 45 F.4th 1373, 1386

(Fed. Cir. 2022) (explaining appellants “forfeit[] any argument on

appeal . . . by failing to present anything more than a conclusory,

skeletal argument”).

17a

are “selectable for receiving,” suggesting that adding

or deleting could relate to making channels selectable

or non-selectable. In light of the overall language of the

claim, we understand “adding or deleting channels” as

including adding a channel either by adding it to the

user interface or making it selectable and deleting a

channel either by removing it from the user interface

or by making it non-selectable. Indeed, the claims do

not specify what is meant by adding or deleting, and

the language is broad enough to encompass either

changing the ability to select the channel or changing

the user interface. Had the patentee intended to limit

the claims to modifying the display to include a new

channel not previously displayed, it could have

included language in the claims to that effect.5

Turning next to the specification, it appears that

the specification treats subscribing to channels interchangeably with adding channels in at least one

embodiment of the patented invention, despite

Comcast’s arguments to the contrary. In describing

Figure 8, the specification states at one point that the

figure is “a flow chart of the method for subscribing

to new content using the global IPG of the instant

invention.” ’431 patent col. 8 ll. 58–59 (emphasis

added). The specification goes on to also describe

5

Comcast’s arguments on claim differentiation are unpersuasive. Comcast points to various dependent claims, none of which

use the term “subscribing,” but instead claim a “digital rights

management module that obtains viewing rights for at least one

of the channels” (claim 3), an IPG that further “assists the user in

managing rights to receive the streaming video programming”

(claim 15), or “automatically authenticat[es] the user to one

or more of the MSO or non-MSO sources” (claim 26). CrossAppellant’s Br. 25 (citation omitted). These terms can all be fairly

interpreted as adding further limitations to an independent

limitation, even if that limitation encompasses subscribing.

18a

Figure 8 as “a flow chart that illustrates the logic

undertaken by a user to add a new content source at

Step 800.” Id. at col. 15 ll. 13–14 (emphasis added).

Figure 8 and the specification’s description of it thus

lend support to WhereverTV’s broader reading of the

adding or deleting channels limitation. Moreover,

Comcast does not point to anything in the specification

that explicitly limits the step of adding or deleting

channels to exclude subscribing and unsubscribing.

Based on the claim language and the specification,

we agree with WhereverTV’s interpretation that

“wherein the application allows for the IPG to be

configured by a user with respect to adding or deleting

channels” encompasses making the channel selectable

and non-selectable on the IPG through subscribing

and unsubscribing.

III

We have also considered Comcast’s assertion that

the district court erred in its construction of the

limitation “wherein the server is distinct from at least

one of the one or more MSOs and one or more nonMSOs” in claim 1. We disagree and adopt the district

court’s construction.

Comcast proposes that this limitation “reflects the

invention’s goal of freeing users from the ‘traditional

cable-television, content aggregation model where the

MSO, rather than the user, is in control of what

content is available,’” Cross-Appellant’s Br. 58 (quoting

’431 patent col. 2 ll. 41–43), and should be construed to

mean that the limitation requires a server that is

“distinct from” Comcast itself. Id. at 58–59. But this

proposal improperly imports unclaimed limitations

into the term. Comcast seeks to import the overarching goal of the patented invention into the term

19a

“distinct from.” But if the patentee had wanted to

claim a server that was not controlled by a cable

company, the patentee could have used language to

that effect. Comcast further seeks to import into this

limitation that MSO means a cable company as a

business entity.6 Comcast makes this argument

despite (1) Comcast not explicitly disputing on appeal

the district court’s separate construction of MSO that

defines the term in a functional sense—i.e., as “a cable,

satellite, or Internet television content consolidator

that receives and then broadcasts channels of video

content,” Claim Construction Order, at *3 (emphasis

added); and (2) the specification also referencing MSOs

with respect to functionality, see, e.g., ’431 patent col. 7

ll. 46–51; see also J.A. 11464. We agree with the district

court that, in the context of the ’431 patent, “[t]o say

that an MSO is a cable company simply because an

MSO is a part of a cable company appears to be an

invalid syllogism distorting the plain meaning of the

terms in question.” J.A. 11464. We are thus unpersuaded that the district court erred in reaching its

underlying factual findings and ultimate construction

of the “distinct from” term based on the language in

the claims, the prior constructions by the district court

6

As the district court acknowledged, importing into the term

that the claimed MSO is Comcast would be to import not just

Comcast’s ability to consolidate and broadcast video content, but

its entire business, including its “billing, accounting, legal, HR,

and IT departments” and any other services it provides, like

“internet and phone services.” J.A. 11463. As WhereverTV

crystalized on appeal, to say that a server is distinct from a

corporation like this would create a claim term that falls outside

the understanding of a person of ordinary skill and would instead

concern legal questions over who controls said server. See

Appellant’s Reply Br. 31–32. We see no reason in either the

intrinsic or extrinsic record here to read in such a meaning to this

claim limitation.

20a

that Comcast has not challenged, the specification,

and the extrinsic evidence in the form of dictionary

definitions and expert testimony.

IV

Finally, we reject Comcast’s indefiniteness argument raised on cross-appeal. Comcast asserts that

the phrase “only or virtually entirely” in the limitation

“wherein each of the channels is selectable for

receiving only or virtually entirely streaming video

programming” is indefinite. We agree with the district

court and WhereverTV that this limitation “can be

understood by those skilled in the art.” Claim Construction Order, at *3.

Reading the limitation in the context of claim 1 as a

whole supports our holding. The limitation recites:

“wherein each of the channels is selectable for

receiving only or virtually entirely streaming video

programming from its respective MSO or non-MSO

source via the communications link and the network.”

Comcast itself proposed that the limitation be interpreted as “wherein each of the channels is configured

such that, in immediate response to selection of its

assigned channel number, and without further searching, video programming is only or virtually entirely

transmitted over the Internet . . . and made available

for viewing while the transmission is occurring.” Id.

Thus, the parties appear to agree that streaming

means transmission over the Internet. See Appellant’s

Reply Br. 45; Construction Order, at *3. And despite its

arguments on appeal, Comcast also appeared to agree

at claim construction that “only or virtually entirely”

modifies streaming of video programming, such that

the claim requires “only or virtually entirely” steaming

video programming. See Construction Order, at *3. In

this context, we agree with the district court that the

21a

limitation is not indefinite. In the context of this claim,

the term “virtually”—similar to terms like substantially, about, and nearly—is simply a term of degree

that modifies entirely. It does not render the claim

indefinite. See One-E-Way, Inc. v. Int’l Trade Comm’n,

859 F.3d 1059, 1067 (Fed. Cir. 2017) (“While we note

that ‘virtually’ is a term of degree, one that slightly

expands the scope of the term . . . ,[] the inclusion of

‘virtually’ in these claims does not render them

indefinite.” (citation omitted)).

Comcast agrees that “virtually” is a term of

degree, but suggests that the patent fails to provide

any “standard for measuring that degree.” CrossAppellant’s Br. 66–67 (citation omitted). But our case

law does not foreclose the use of terms of degree

in claims, and as discussed, here the inclusion of

“virtually” slightly expanded the scope of the claim

from receiving only streaming video programming

data to also include receiving effectively or almost

entirely streaming video programming data, the bounds

of which a skilled artisan would be informed of.

* * *

In light of the proper construction of claim 1’s IPG

application limitation and adding or deleting channels

limitation, as well as our decisions on Comcast’s alternative arguments, we remand WhereverTV’s infringement allegations to the district court for trial to

determine infringement based on the correct construction of the claim terms. See Rambus Inc. v. Infineon

Techs. Ag, 318 F.3d 1081, 1095 (Fed. Cir. 2003) (“In

sum, the district court erred in its construction of each

of the disputed terms. In light of the revised claim

construction, this court vacates the grant of JMOL of

noninfringement and remands for the district court to

reconsider infringement.”).

22a

CONCLUSION

We have considered Comcast’s remaining arguments and find them unpersuasive. For the foregoing

reasons, we vacate the district court’s JMOL of noninfringement and remand for further proceedings

consistent with this opinion.7

APPENDIX B

UNITED STATES DISTRICT COURT

MIDDLE DISTRICT OF FLORIDA

FORT MYERS DIVISION

————

Case No: 2:18-cv-529-WFJ-NPM

————

WHEREVERTV, INC.,

v.

Plaintiff,

COMCAST CABLE COMMUNICATIONS, LLC,

Defendant.

————

ORDER

On April 26, 2023, following the parties’ presentation of evidence during a six-day jury trial, the Court

granted Defendant Comcast Cable Communications,

LLC’s (“Comcast”) Rule 50(a) Motion for Judgment as

a Matter of Law, Dkt. 409. See Dkt. 414. At the Court’s

invitation, Plaintiff WhereverTV, Inc. (“WTV”) and

Comcast filed supplemental briefs on the Court’s

ruling. Dkts. 428 & 429. Both parties also submitted

rebuttal briefs. Dkts. 430 & 431. Upon careful consideration and in accordance with its earlier ruling,

the Court directs final judgment to be entered in favor

of Comcast and against WTV.

BACKGROUND

Founded in 2006, WTV is a “television service

provider that offers live-streaming video content to

subscribing customers around the world and through

a wide range of internet enabled devices.” Dkt. 30 ¶ 11.

24a

WTV is the assignee and owner of the ‘431 Patent,

which was issued by the United States Patent and

Trademark Office (“USPTO”) in February 2014. Dkt.

418-1. The ‘431 Patent discloses “[a] system and

device . . . that employs a global interactive program

guide [‘IPG’] to receive, access, manage, and view

digital entertainment services such as live television,

television on demand, and pre-recorded video and

audio programming from one or more content sources,

via an internet-enabled device, anywhere in the

world.” Id. at 1. The ‘431 Patent states that “[t]he goal

is to shift control of content availability, organization,

and access from MSO’s [multi system operators],

which is today’s cable television model, to a new usercentric model where the user can choose whether or

not to purchase content from a content consolidator or

directly from independent content providers.” Id. at 15.

In 2009, cable television and internet provider

Comcast began developing an entertainment platform

known as the Xfinity X1 (the “X1”). Dkt. 30 ¶ 24; Dkt.

420 at 122. The X1 allows users to access video content

from their cable provider and streaming providers

through a “cloud-based system.” See, e.g., Dkt. 420

at 118−20, 136. Among other components, the X1 is

comprised of the XRE1 receiver, which is located on

the X1 set-top box, and the cloud-based XRE server.

See Dkt. 417-3 at 9.

In 2018, WTV filed the instant action against

Comcast, claiming that Comcast “directly infringed

and continues to directly infringe all the claims of the

‘431 Patent . . . by making, using, offering for sale, and

1

The acronym “XRE” stands for Xcalibur rendered engineering, with “Xcalibur” being Comcast’s initial internal name for the

Xfinity project. See Dkt. 420 at 121, 129.

25a

selling the Xfinity X1 Platform.” Dkt. 30 ¶¶ 47–48.

Claim 1, the independent claim that remains the sole

issue in the case, reads in full:

1. a content manager device comprising:

a server resident on a network containing

descriptive program data about video content

available from one or more multiple cable

system operators (MSOs) and one or more

non-MSOs;

a device capable of establishing and maintaining a connection with the network via

communications link; and

an interactive program guide application

installed on the device that provides userconfigurable interactive program guide

(IPG) listing at least one channel of video

content available from each of the one or

more MSOs and descriptive program data

from the server for the video content

available on each of the channels, wherein

each of the channels is selectable for

receiving only or virtually entirely streaming

video programming from its respective

MSO or non-MSO source via the communications link and the network; wherein

the server is distinct from at least one of

the one or more MSOs and one or more

non-MSOs, and wherein the application

allows for the IPG to be configured by a

user with respect to adding or deleting

channels from any of the one or more

MSOs or the one or more non-MSOs.

Dkt. 418-1 at 20.

26a

Following a Markman hearing in 2020, Chief Judge

Timothy Corrigan issued a claim construction order on

seven disputed terms within Claim 1 and other

dependent claims. Dkt. 172. Finding further construction necessary for only two of those seven terms, Judge

Corrigan construed “multiple cable system operators

(MSOs)” to mean “a cable, satellite, or Internet television content consolidator that receives and then

broadcasts channels of video content” and “non-MSOs”

to mean “a video content provider that does not act like

an MSO because it does not receive and then broadcast

channels of video content.” Id. at 5. Relevant to this

Order, Judge Corrigan declined to construe the terms

“independent program guide” and “adding or deleting

channels from any of the one of more MSOs or the

one or more non-MSOs.” Id. at 8−9. The case was

thereafter transferred to Judge Badalamenti, who

held a second Markman hearing and adopted Judge

Corrigan’s pertinent constructions. Dkt. 302 at 15.

After several amendments to the parties’ case management and scheduling order, the case was set for a

March 2023 jury trial. See Dkt. 326.

One week before the scheduled trial, the trial was

continued, Dkt. 365, and the case was transferred to

the undersigned, Dkt. 374. A jury trial before the

undersigned subsequently commenced on April 19,

2023. By that time, the parties had narrowed the case

to the WTV’s claim of literal infringement of Claim 1

of the ‘431 Patent. At the close of WTV’s case, Comcast

moved for judgment as a matter of law under Federal

Rule of Civil Procedure 50(a), asserting a lack of

sufficient evidence showing that the X1 meets

Claim 1’s “adding or deleting channels” limitation or

“interactive program guide application installed on

the device” limitation. Dkt. 409. The Court took oral

argument on Comcast’s motion outside the presence of

27a

the jury following the parties’ closing arguments on

the sixth day of trial. Dkt. 424 at 127−55. Finding that

no reasonable jury could find direct infringement of

the “adding or deleting channels” or the “interactive

program guide application installed on the device”

limitations, the Court granted Comcast judgment as a

matter of law. Id. at 155−56. This final Order follows.

LEGAL STANDARD

Pursuant to Federal Rule of Civil Procedure 50(a), a

“district court should grant judgment as a matter of

law when the plaintiff presents no legally sufficient

evidentiary basis for a reasonable jury to find for

[plaintiff] on a material element of [plaintiff ’s] cause

of action.” Pickett v. Tyson Fresh Meats, Inc., 420

F.3d 1272, 1278 (11th Cir. 2005) (citations omitted).

Accordingly, a court should grant a Rule 50(a) motion

“only if the evidence is so overwhelmingly in favor of

the moving party that a reasonable jury could not

arrive at a contrary verdict.” Middlebrooks v. Hillcrest

Foods, Inc., 256 F.3d 1241, 1246 (11th Cir. 2001). In

deciding a Rule 50(a) motion, a court must view all

evidence and draw all reasonable inferences in the

non-moving party’s favor. Walker v. NationsBank of

Fla., N.A., 53 F.3d 1548, 1555 (11th Cir. 1995).

ANALYSIS

In moving for judgment as a matter of law, Comcast

asserts that WTV failed to present sufficient evidence

for a reasonable jury to conclude that the X1 meets

each and every limitation of Claim 1. Specifically,

Comcast avers that no reasonable jury could find that

the X1 meets either the “adding or deleting channels”

limitation or the “interactive program guide application installed on the device” limitation.

28a

Because WTV is arguing that the X1 “literally

infringed” the ‘431 Patent, WTV has the burden of

proving by a preponderance of the evidence that the

X1 literally embodies every limitation of Claim 1. See

Revolution Eyewear, Inc. v. Aspex Eyewear, Inc., 563

F.3d 1358, 1369 (Fed. Cir. 2009); Biovail Corp. Int’l v.

Andrx Pharms., Inc., 239 F.3d 1297, 1302 (Fed. Cir.

2001) (“Literal infringement requires a patentee to

prove by a preponderance of the evidence that every

limitation of the asserted claim is literally met.”). “If

any claim limitation is absent from the accused device,

there is no literal infringement as a matter of law.”

Bayer AG v. Elan Pharm. Research Corp., 212 F.3d at

1247.

The Court notes that literal infringement is distinct

from infringement under the doctrine of equivalents,

which “requires that the accused product contain each

limitation of the claim or its equivalent.” See Cortland

Line Co. v. Orvis Co., 203 F.3d 1351, 1359 (Fed. Cir.

2000) (emphasis added). Unlike the doctrine of

equivalents, which dictates that infringement can be

found so long as the differences between the accused

product and a claim element are “insubstantial” to one

of ordinary skill in the art, see Warner-Jenkinson Co. v.

Hilton Davis Chem. Co., 520 U.S. 17, 40 (1997), literal

infringement requires more exactitude, see Southwall

Techs., Inc. v. Cardinal IG Co., 54 F.3d 1570, 1575 (Fed.

Cir. 1995) (“To establish literal infringement, every

limitation set forth in a claim must be found in an

accused product, exactly.”).

A literal infringement analysis involves two steps.

“First, the asserted claims must be interpreted by the

court as a matter of law to determine their meaning

and scope. In the second step, the trier of fact

determines whether the claims as thus construed read

29a

on the accused product.” Id. (internal citations omitted).

The Court considers the sufficiency of WTV’s evidence2

with respect to the two disputed limitations in turn.

I. “Adding or Deleting Channels” Limitation

Relevant to the “adding or deleting channels”

limitation, Claim 1 states that “the application allows

for the IPG to be configured by a user with respect to

adding or deleting channels from any of the one or

more MSOs or the one or more non-MSOs.” Dkt. 30-1

at 19. WTV’s infringement argument hinges on its

understanding of “adding or deleting.”

At trial, WTV argued that an X1 user who subscribes (or unsubscribes) to a particular channel

offered by Comcast on X1 has added (or deleted) that

channel within the meaning of those terms as used in

Claim 1. See, e.g., Dkt. 419 at 198. For example, WTV

explained in its opening argument that, with the X1,

“[y]ou can add and delete channels. You can manage

subscriptions right there through the X1 guide. . . .

If you want to add the Starz channel, Showtime

channel, Cinemax channel, Movie channel, Netflix

channel, you can add any of them.” Id. Thus, WTV

contends that the X1 infringes Claim 1 because a user

managing subscriptions to channels is akin to a user

adding or deleting channels.

However, because WTV abandoned its infringement

claims under the doctrine of equivalents, WTV cannot

prevail merely by showing that “subscribing” to a

2

The evidence was closed on April 27, 2023, at the conclusion

of trial. In connection with its supplemental, post-trial brief

on this matter, WTV filed fourteen exhibits—including a new

declaration from its expert—on the docket eighteen days after the

close of evidence and this Court’s ruling. See Dkt. 428 (exhibits).

Untimely evidence will not be considered.

30a

channel is substantially the same as, or similar to,

adding a channel to the IPG. WTV must instead show

by a preponderance of the evidence that subscribing is

literally “adding” and that unsubscribing is literally

“deleting.” This means that the X1 cannot be said to

literally infringe the “adding or deleting channels”

limitation unless a user can, in fact, add or delete a

channel from the IPG.

After reviewing the evidence presented at trial, the

Court finds that WTV did not meet its burden of proof

as to this literal infringement argument. Specifically,

WTV did not introduce sufficient evidence at trial for

a reasonable juror to conclude that the X1’s IPG can

“be configured by a user with respect to adding or

deleting channels.” Thus, as the Court explains below,

WTV has failed to establish literal infringement.

A. Because the Court declined to construe the

“adding or deleting” channels limitation, the

Court interprets the term according to its

plain and ordinary meaning.

The Court twice engaged in claim construction in

this case, and both times it declined to construe the

adding or deleting channels limitation. Dkt. 172 at

8-9; Dkt. 302 at 15. WTV stated that the Court should

use the plain and ordinary meaning of “adding or

deleting.” See Dkt. 172 at 8−9. On two separate

occasions WTV had the opportunity to move the Court

to construe “adding or deleting channels” in a manner

that would explicitly accommodate “subscribing and

unsubscribing.” Id.; see also Dkt. 302 at 15. WTV did

not do so on either occasion. Nor did either party move

31a

to have the “adding or deleting channels limitation”

construed during trial.3

The Federal Circuit has repeatedly held that a

district court is not obligated to construe terms

with ordinary meanings. See, e.g., Biotec Biologische

Naturverpackungen GmbH & Co. KG v. Biocorp, Inc.,

249 F.3d 1341, 1349 (Fed. Cir. 2001) (finding no error

in non-construction of “melting”); Mentor H/S, Inc. v.

Med. Device All., Inc., 244 F.3d 1365, 1380 (Fed. Cir.

2001) (finding no error in court’s refusal to construe

“irrigating” and “frictional heat”). Generally, there is a

“heavy presumption in favor of the ordinary meaning

of claim language.” See Johnson Worldwide Assocs. v.

Zebco Corp., 175 F.3d 985, 989 (Fed. Cir. 1999). And

where a district court determines that a claim term

does not require further construction, that term

receives its plain and ordinary meaning as understood

by a person of skill in the art. See Phillips v. AWH

Corp., 415 F.3d 1303, 1314 (Fed. Cir. 2005). “In some

cases, the ordinary meaning of claim language as

understood by a person of skill in the art may be

readily apparent even to lay judges, and claim

construction in such cases involves little more than the

application of the widely accepted meaning of commonly

understood words.” Id.; see also Brown v. 3M, 265 F.3d

1349, 1352 (Fed. Cir. 2001) (“We agree with this

construction of the claim, for it is the plain reading of

the claim text. These are not technical terms of art,

and do not require elaborate interpretation.”).

3

The Court notes that Comcast orally requested after the close

of evidence that “if the Court is inclined to submit the issue to the

jury, as we’re aware courts often do, we object to the failure to

construct and request that the term be construed.” Dkt. 424 at 134.

32a

Here, “adding” and “deleting” are not used idiosyncratically and do not have discrete, technical

meanings within the field of art, as WTV noted. See

Dkt. 172 at 8−9. The prior judges’ decisions to not

further construe “adding or deleting” was therefore in

accord with the significance of these terms and the role

that these terms play within the context of Claim 1 of

the ‘431 Patent. As such, these terms will receive their

plain and ordinary meaning. See Phillips, 415 F.3d

at 1312 (“Because the patentee is required to define

precisely what his invention is . . . it is unjust to the

public, as well as an evasion of the law, to construe it

in a manner different from the plain import of its terms.”).

To determine the plain and ordinary meaning of a

claim term, courts may look to general purpose

dictionaries. See id. at 1314. Merriam-Webster’s

Dictionary defines “add” as “to join or unite so as to

bring about an increase or improvement” and “delete”

as “to eliminate especially by blotting out, cutting out,

or erasing.” Add, Merriam-Webster Dictionary, https://

www.merriam-webster.com/dictionary/add (last visited

May 31, 2023); Delete, Merriam-Webster Dictionary,

https://www.merriam-webster.com/dictionary/delete (last

visited May 31, 2023). The Oxford English Dictionary

defines “add” as “[t]o join (something) to something

else so as to increase the amount, size, importance,

etc.; to put in as an additional element or ingredient”

While dictionary definitions alone are not controlling as to the plain and ordinary meaning of a

particular claim term, they are “useful to assist in

understanding the commonly understood meaning of

words” where, as here, there is no competing artspecific evidence of meaning. See Phillips, 415 F.3d

at 1322. The Court therefore reiterates the earlier

claim construction order determining that “adding or

deleting channels” is afforded its plain meaning. No

further claim construction is required as commonsense, ordinary understandings of “adding” and “deleting”

are confirmed by the above referenced dictionary

definitions, and the parties have introduced no evidence

tending to yield more than one “ordinary” meaning for

these terms. Nor did WTV request the same.

B. Channels cannot be added or deleted on the X1

under the plain meaning of “add” and “delete,”

meaning the X1 does not literally infringe

Claim 1.

The second step in the literal infringement analysis

asks, “whether the claims as thus construed read on

the accused product.” Southwall Techs., 54 F.3d at

1575. As explained below, WTV did not introduce any

evidence at trial that X1 users can add or delete

channels in a manner that accords with the plain and

ordinary meaning of those terms. WTV therefore failed

to show by a preponderance of the evidence that the

X1 literally infringes the “adding or deleting channels”

limitation of Claim 1.

WTV premised its infringement argument on its

contention that a user “managing subscriptions” is the

34a

same as that user “adding or deleting channels.” Dkt.

419 at 198. WTV first made this argument in its

claim construction briefing asserting that “[a]dding a

channel refers to ‘integrating’ the channel into the

IPG. One way to add a channel to the IPG is to

subscribe to the channel.” Dkt. 96 at 25. At the first

Markman hearing, however, the previously assigned

judge expressed skepticism as to this syllogism,

asking, “Why would you add to the guide something

that’s already there, and why would you delete from

the guide something that’s going to be there after you

delete it? I don’t get it.” Dkt. 165 at 132. That concern

highlights the issue with respect to WTV’s infringement argument on this particular limitation.

To begin, in attempting to elide plain English and

get the jury to adopt its narrow and idiosyncratic

reading of “adding or deleting,” WTV improperly

contorted the Court’s instruction as to the scope of the

limitation. At no point during trial did WTV introduce

evidence that an X1 user could subscribe to a channel

that was not already offered on the accused X1’s IPG,

thereby increasing the number of channels offered on

the IPG. Nor did WTV introduce any evidence that a

user who unsubscribed from a particular app—such as

Netflix—could remove that app from the X1’s IPG

entirely such that search results for content contained

in that app would not appear or that the app would not

be displayed on the IPG. Thus, by encouraging the jury

to accept that subscribing is adding and unsubscribing

is deleting, WTV encouraged a departure from the

plain and ordinary meaning of these terms.

Even if WTV could argue that subscribing is like

adding, under the plain and ordinary meaning of

adding, mere equivalence is not enough to satisfy

literal infringement. Again, to argue literal infringe-

35a

ment, WTV must state that subscribing is adding and

unsubscribing is deleting. WTV may not assert literal

infringement based on the theory that unsubscribing

from an app—so as to restrict that app’s content by

“graying it out” or placing it behind a paywall or a

request for credentials—is conceptually similar to

deleting that app simply because both actions create

impediments for the user who wants to watch content

offered by the app. WTV must show that an X1 user

can actually delete the app from the IPG. WTV,

however, has introduced no evidence that this is

possible, and in fact, its witnesses confirmed just the

opposite. One cannot delete a channel from the X1. Nor

can one add a channel that Comcast did not deign to

include. WTV’s case in chief failed to prove that the X1

user can add or delete channels.

In its case in chief, WTV called Jessica Sant, who

leads the team that builds the X1 user interface at

Comcast, to testify. Dkt. 421 at 79. When asked how a

user can add or delete apps from the IPG on the X1,

Ms. Sant stated, “[i]t’s not possible. All the apps that

are available to a customer are listed here. There’s no

way for a customer to add an app or remove it.” Id. at

80. Ms. Sant elaborated that a user could not add or

delete an app because “[t]hat’s simply not how the

system was designed. All the channels that are

available to a customer are present in the guide, in the

IPG, whether or not they are subscribed to them.” Id.

In sum, Ms. Sant testified that subscribing to or

authenticating a channel cannot be “adding” that

channel to the X1 IPG because, irrespective of the

user’s actions, the channel—including its content and

metadata—will be present on the IPG. That is, “[t]he

rows that exist are all there[.] There’s no way to add or

remove them.” Id.

36a

WTV’s technology expert, Dr. William C. Easttom II,

confirmed this fact. Dr. Easttom testified that new

channels cannot be added to the X1 IPG because when

a user searches for content on the X1 system, the

system will “show you every place you can watch it”

and provide “a listing of all of them in one single IPG.”

Dkt. 420 at 148. Thus, when a user searches for

particular content on the X1, the results yielded by the

X1 will include every channel containing that content,

irrespective of whether the user is subscribed to the

channel. Id. As Dr. Easttom testified, even if a user did

not want the Netflix app on her X1’s IPG and had no

intention of ever subscribing to Netflix, the Netflix app

would still appear, and the user would not be able to

delete it. Id. at 277. In this regard, Dr. Easttom

essentially conceded that the user cannot “configure

the IPG with respect to adding or deleting channels,”

as Claim 1 requires given that, irrespective of the

user’s personal preferences as to what channels

appear on the IPG, all channels offered by Comcast

would still be displayed on the IPG. See id.

Ms. Sant and Dr. Easttom’s testimony regarding the

rigidity of the X1’s IPG display and the immutability

of the channel listings provided by Comcast is in no

way identical to the customizable and restriction-free

invention described in the ‘431 Patent’s specification.

That specification explains in relevant part:

The present invention allows a user to move

from location to location and easily acquire,

organize and view digital entertainment content from one or more independent content

sources (including channel listings, programming information, and saved content) via a

“follow me” personalized global IPG that is

available on any device that is connected to

37a

the Public Internet. The goal is to shift the

control of content availability, organization,

and access from MSO’s, which is today’s cable

television model, to a new user-centric model

where the user can choose whether or not to

purchase content from a content consolidator

or directly from independent content providers.

Dkt. 30-1 at 14. Users of the X1 cannot “easily acquire

. . . content,” and they have no “control of content

availability” because, as Ms. Sant testified, the X1 does

not allow users to pick and choose whatever channels

they want on their devices. See Dkt. 421 at 92

(Ms. Sant explaining, “One of the reasons that we

designed it that way is so that Comcast can really

control what content is available to our customers so

we can provide a really high-quality experience so

there’s not any rogue content on the system.”). Simply

put, the role that “adding or deleting channels” plays

in the ‘431 Patent’s efforts to permit users to pick and

choose what content is available to them, wherever

they are in the world, is totally dissimilar to the role

that “managing subscriptions” plays on the X1. While

the ‘431 Patent allows users to increase the number of

channels available to them—true to the plain and

ordinary meaning of “adding”—the X1 only allows

users to log in and out of channels that Comcast, and

only Comcast, chose irrevocably to emplace on the IPG.

In sum, WTV has not shown that a user’s ability to

manage subscriptions on the X1 literally embodies a

user’s ability to add or delete channels as described in

Claim 1. Instead, the evidence introduced by WTV at

trial highlights the marked dissimilarities between

the ‘431 Patent and the X1, particularly vis-à-vis what

the inventor described as the “goal” of the invention—

to allow a user to exercise full, unrestricted dominion

38a

over the content available to her on the IPG. See Dkt.

30-1 at 14. For these reasons, the Court finds that no

reasonable juror could find that WTV has shown by a

preponderance of the evidence that the X1 literally

infringes the “adding or deleting channels” limitation

of Claim 1.

II. “Interactive Program Guide Application

Installed on the Device” Limitation

Turning to the second disputed limitation, Claim 1

also calls for an “interactive program guide application

installed on the device[.]” Dkt. 418-1 at 20. At trial,

WTV maintained that the X1 meets this limitation

because the XRE receiver, which the parties agree is

installed on the X1 set-top box (i.e., “the device”), is an

IPG application. However, no reasonable jury could

make this finding based upon the evidence presented

at trial. As set forth below, there is insufficient

evidence to support a finding of literal infringement.

A. Because the Court declined to construe

the “interactive program guide application

installed on the device” limitation, the term

is afforded its plain and ordinary meaning.

As with the “adding or deleting channels” term, the

Court previously declined to further construe “interactive program guide” or “interactive program guide

application” during either claim construction. Dkt. 172

at 8; Dkt. 302. WTV suggested that this term should

have a “plain and ordinary meaning, namely a

program guide that enables user interaction.” Dkt. 172

at 8. Accordingly, the term “interactive program guide

application” receives its plain and ordinary meaning

as understood by a person of ordinary skill in the art

in question at the time of the invention. Phillips, 415

F.3d at 1312−13. Notably, “the person of ordinary skill

39a

in the art is deemed to read the claim term not only

in the context of the particular claim in which the

disputed term appears, but in the context of the entire

patent[.]” Id. at 1313.

Where, as here, a term’s plain and ordinary meaning

is not readily apparent, courts look to “those sources

available to the public that show what a person of skill

in the art would have understood the disputed claim

language to mean,” including “the words of the claims

themselves, the remainder of the specification, the

prosecution history, and extrinsic evidence concerning

relevant scientific principles, the meaning of technical

terms, and the state of the art.” Id. at 1314 (quoting

Innova/Pure Water, Inc. v. Safari Water Filtration Sys.,

Inc., 381 F.3d 1111, 1116 (Fed. Cir. 2004)); see also

Medrad, Inc. v. MRI Devices Corp., 401 F.3d 1313, 1319

(Fed. Cir. 2005) (“We cannot look at the ordinary

meaning of the term . . . in a vacuum.”). It is with this

understanding that the Court considers whether WTV

offered sufficient evidence to show literal infringement

of the “interactive program guide application installed

on the device” limitation.

B. The X1 does not literally infringe Claim 1

because the X1 does not have an “interactive

guide application program installed on the

device.”

When considering the meaning of an “interactive

program guide application” as understood by a person

of ordinary skill in the art, it is apparent that WTV

failed to present sufficient evidence to show that the

X1 has an “interactive program guide application

installed on the device.” WTV therefore failed to carry

its burden to show that the X1 literally infringed this

limitation.

40a

Turning first to the claim language, Claim 1

requires “an interactive program guide application

installed on the device that provides user-configurable

interactive program guide (IPG) listing at least one

channel of video content . . . and descriptive program

data from the server for the video content available on

each of the channels.” Dkt. 418-1 at 20 (emphasis

added). This language plainly describes a client-server

architecture in which the interactive program guide

application is installed on the device, i.e., the set-top

box, and descriptive program data resides on a server.

Though Dr. Easttom asserted that the X1 utilizes this

architecture, see Dkt. 420 at 135−36, it is undisputed

that the X1 has an “XRE guide” application that exists

and runs not on the X1 set-top box. Rather, the XRE

guide is installed and runs “on servers in the cloud”—

namely, the XRE server. Id. at 284. Dr. Easttom

acknowledged that it is this XRE guide application

that “directs the set-top box as to what to display” and

“generates rendering instruction for the XRE receiver”

with respect to the IPG. Id. at 284. Therefore, the

uncontested evidence shows that the interactive

program guide application is not installed on the

device (the set-top box).

Despite the undisputed existence that the “XRE

guide application” in the cloud provides all the data

assembly and “brains” necessary for the interactive

program guide, WTV maintained throughout trial that

the XRE receiver on the set-top box is the X1’s IPG

application. However, the ‘431 Patent’s specification

does not support this conclusion. Figure 84 in the ‘431

Patent depicts an IPG application that, among other

4

WTV specifically directed the Court to Figures 7 and 8 of

the ‘431 Patent in arguing its opposition to the instant motion.

Dkt. 424 at 139−40, 150−52.

41a

things, “procures digital rights via stored profile,”

“locates and authenticates” new content sources, and

“downloads and synchronizes content metadata from

new content sources.” Dkt. 418-1 at 12. Indeed, counsel

for WTV conceded that Figure 8 is, “in a sense,” a

helpful illustration to understand the functions of an

interactive program guide application. Dkt. 424 at 153.

Moreover, Figure 4 within the ‘431 Patent serves as “a

conceptual architectural diagram of the global IPG

application.” Dkt. 418-1 at 16. Figure 4 depicts the

invention’s IPG application as having “Core Application

Features” such as data integration, user authentication, and customization and personalization of the

IPG, as well as “Core Application Functions” like

content subscription management, content organization management, and user profile management. Id.

at 8, 18.

WTV presented no evidence that the XRE receiver

in the X1 set-top box “device” offers any of the

functions or features illustrated in Figures 4 or 8.

Instead, Dr. Easttom testified that the XRE receiver is

a “thin client”5 capable of performing only two major

functions: “draw[ing] what you see on the screen pixel

by pixel” and sending “whatever input you give it

through the remote control” to the cloud-based XRE

server, “which may send data back.” Dkt. 420 at 189,

285. In other words, at best WTV proved the accused

device (the X1 set-top box) is a thin client, signaling

device, and WTV never showed that the interactive

program guide application was installed therein. This

was confirmed by WTV’s counsel, who described the

XRE receiver as a “graphics program.” Dkt. 424 at

5

In computing parlance, a “thin client” is a system with limited

processing power, whereas a “fat client” is a system with greater

processing power. See Dkt. 420 at 284−85; Dkt. 423 at 58.

42a

148−49. How a “graphics program” constitutes an

“interactive program guide application” was never

made clear.

Moreover, both parties’ experts agreed that Comcast

intentionally designed the X1 set-top boxes to work as

thin clients that do not execute application logic.6

Dkt. 423 at 58 (Dr. Terveen); Dkt. 420 at 201−02, 285

(Dr. Easttom). Dr. Terveen explained that, while

placing IPG applications on set-top boxes “was really

the way things worked in the industry” at the time of

the ‘431 Patent application in 2006, Comcast chose to

depart from “the old way of doing things” by placing

the X1’s IPG application on a cloud-based server that

executes all application logic. Dkt. 423 at 45−46, 58.

Dr. Terveen testified without contradiction that

Comcast made this decision because a server has “a lot

more computational power than a set-top box,” and

Comcast could update the IPG application on the

server instead of requiring customers to download

updated versions onto their set-top boxes. Id. at 47;

see also Dkt. 420 at 202, 283−84 (Dr. Easttom similarly

testifying that Comcast does not “have to change the

receiver every single time something changes in [the]

back end” because the application logic is executed

on the XRE server). Due to this design choice, it is

undisputed that the cloud-based XRE server, and

not the XRE receiver, provides “the data necessary for

the . . . IPG.” Dkt. 420 at 189 (Dr. Easttom).

Ultimately, while the XRE receiver in the X1 set-top

box may be an “application installed on the device,”

WTV failed to sufficiently demonstrate that the XRE

6

The parties’ experts described this “application logic” as how

the IPG application processes user inputs, such as remote key

presses, “behind the front end.” See Dkt. 420 at 201; Dkt. 423 at 58.

43a

receiver constitutes an “interactive program guide

application installed on the device” as understood by a

person of ordinary skill in the art. This is particularly

evident in light of the language of Claim 1, the ‘431

Patent specification, and relevant proof at trial.

With insufficient evidence for a reasonable jury to find

that the X1 meets the “interactive program guide

application installed on the device” limitation, WTV

cannot show the X1’s literal infringement of Claim 1 of

the ‘431 Patent.

CONCLUSION

Based on the foregoing, Comcast is entitled to

judgment as a matter of law. The Clerk is directed to

enter final judgment in favor of Comcast and against

WTV and close this case.

THE COURT: All right. Notwithstanding the

forensic -- substantial forensic skills shown by the

plaintiff, I’m granting the motion. I find that this is

literal infringement. There’s no legally -- legally appropriate evidence for a reasonable jury in a light

viewed most favorable to the plaintiff, including its

inferences, to find infringement for the two reasons

that we’ve discussed.

I’ve evaluated all the evidence and find that the

Rule 50 standard applies. so the motion is granted. I

rule against the plaintiff and for the movant.

I’m going to put a final order out on this -not a

final order -- final order out on this June 2nd. If

anybody wants to do substantive briefing, that date -deadline is may 14th. And the -- and the -- any

rebuttal pleadings, if you wish, is may 24th. I’ll issue

the order June 7th.

I find that the two terms that we’ve discussed,

the interactive program guide installed on a device

and also the adding and deleting portions of Claim 1,

are not net by the plaintiff.

Anything else, plaintiff?

[156]

Hearing nothing.

Anything else -- yes?

MR. ROSENTHAL: Your Honor, I’d just move to

reconsider that the -- you cannot as a matter of law -the Federal circuit has been very clear. You cannot

import limitations to the claim from a specification.

THE COURT: All right. well, I’ve taken argument

So thank you. Any substantive -- the case is over.

I’ve granted the JMOL under Rule 50.

WHEREVERTV, INC.,

v.

Plaintiff,

COMCAST CABLE COMMUNICATIONS, LLC,

————

Defendant.

ORDER

In this patent infringement action, WhereverTV, Inc.

alleges that Comcast Cable Communications, LLC’s

Xfinity X1 Platform infringes on a patent owned by

WhereverTV, U.S. Patent No. 8,656,431 B2, titled

Global Interactive Program Guide Application and

Device (the ’431 Patent) (Doc. 30-1). This matter is

before the Court for patent claim construction, as

described in Markman v. Westview Invs., Inc., 52 F.3d

967 (Fed. Cir. 1995) (en banc), aff’d, 517 U.S. 370

(1996). The Court has considered the submissions of

the parties, including the memoranda, exhibits, and

expert declarations (Docs. 95, 95-1, 96, 96-1, 107, 108,

108-1, 109, 109-1, 161, 162), and the argument of

counsel at the June 12, 2020 Markman hearing about

seven disputed claim terms 1 (Doc. 165, transcript).

There were twelve disputed claim terms but to narrow the

scope of disputed issues, Comcast agreed to withdraw its request

1

48a

The record of that hearing is incorporated here by

reference. Following the hearing, the Court made

tentative indications on the record about the parties’

arguments and proposed constructions (Doc. 165 at

140-42) and allowed the parties time to consider

settlement, but they did not settle. (Docs. 168, 169).

I. CLAIM CONSTRUCTION STANDARDS

“The proper construction of a patent’s claims is an

issue of Federal Circuit Law.” Powell v. The Home

Depot U.S.A., Inc., 663 F.3d 1221, 1228 (Fed. Cir. 2011).

“[T]here is no magic formula or catechism for conducting claim construction.” Phillips v. AWH Corp., 415

F.3d 1303, 1324 (Fed. Cir. 2005). Claim construction

begins with the words of the claims themselves.

Allergan Sales, LLC v. Sandoz, Inc., 935 F.3d 1370,

1374 (Fed. Cir. 2019); Phillips, 415 F.3d at 1312. “[T]he

words of a claim ‘are generally given their ordinary

and customary meaning.’” Phillips, 415 F.3d at 1312

(quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d

1576, 1582 (Fed. Cir. 1996)). Such ordinary meaning “is

the meaning that the term would have to a person of

ordinary skill in the art in question at the time of

the invention.” Id. at 1313. “Furthermore, a claim term

should be construed consistently with its appearance

in other places in the same claim or in other claims of

the same patent.” Rexnord Corp. v. Laitram Corp., 274

F.3d 1336, 1342 (Fed. Cir. 2001). Accordingly, “the

specification is always highly relevant to the claim

construction analysis.” Phillips, 415 F.3d at 1315

(quotation marks omitted). This is true because a

as to five disputed terms: “the device,” “digital rights management

module,” “filtering module,” “voice recognition module,” and “relay

module.” For this litigation only, Comcast accepts WhereverTV’s

proposed constructions for those five terms. (Doc. 160).

49a

patentee may define his own terms, give a claim term

a different meaning than the term would otherwise

possess, or disclaim or disavow the claim scope. Id. at

1316.

“[W]hile claims are to be interpreted in light of the

specification and with a view to ascertaining the

invention, it does not follow that limitations from the

specification may be read into the claims.” Comark

Commc’ns, Inc. v. Harris Corp., 156 F.3d 1182, 1186

(Fed. Cir. 1998) (quoting Sjolund v. Musland, 847 F.2d

1573, 1581 (Fed. Cir. 1988)). Importing limitations

from the specification therefore “should be avoided

unless the patentee clearly ‘intends for the claims and

the embodiments in the specification to be strictly

coextensive.’” Pfizer, Inc. v. Ranbaxy Laboratories Ltd.,

457 F.3d 1284, 1290 (Fed. Cir. 2006) (quoting Phillips,

415 F.3d at 1323). “In addition to consulting the specification, ... a court should also consider the patent’s

prosecution history, if it is in evidence 2.... Like the

specification, the prosecution history provides evidence

of how the [Patent and Trademark Office (‘PTO’)] and the

inventor understood the patent.” Phillips, 415 F.3d at

1317 (quotations and citations omitted).

Although intrinsic evidence is preferred, courts may

also rely on extrinsic evidence, which is “all evidence

external to the patent and prosecution history, including expert and inventor testimony, dictionaries, and

learned treatises.” Markman, 52 F.3d at 980.

II. THE PATENT

The ’431 Patent discloses novel methods and systems

for receiving, accessing, managing and viewing digital

to Doc. 94.

50a

entertainment services such as live television, television on demand, and pre-recorded video and audio

programming from one or more content sources via

an Internet-enabled device. To access the video content, the user uses an interactive programming guide

application. The ’431 Patent states that “[t]he goal is

to shift control of content availability, organization,

and access from MSO’s, [multi system operators],

which is today’s cable television model, to a new usercentric model where the user can choose whether or

not to purchase content from a content consolidator or

directly from independent content providers.” (Doc.

30-1 at 6:39-44).

The text of Claim 1, the asserted independent claim,

reads in full:

1. a content manager device comprising:

a server resident on a network containing

descriptive program data about video content

available from one or more multiple cable

system operators (MSOs) and one or more

non-MSOs;

a device capable of establishing and maintaining a connection with the network via a

communications link; and

an interactive program guide application

installed on the device that provides userconfigurable interactive program guide (IPG)

listing at least one channel of video content

available from each of the one or more MSOs

and descriptive program data from the server

for the video content available on each of

the channels, wherein each of the channels is

selectable for receiving only or virtually

entirely streaming video programming from

51a

its respective MSO or non-MSO source via

the communications link and the network;

wherein the server is distinct from at least

one of the one or more MSOs and one or

more non-MSOs, and wherein the application

allows for the IPG to be configured by a user

with respect to adding or deleting channels

from any of the one or more MSOs or the one

or more non-MSOs.

(Doc. 30-1 at 16:32-54).

III. CLAIM CONSTRUCTION

The claims for the Markman hearing are seven

disputed terms recited in independent Claim 1 and

dependent Claims 8, 9 of the ’431 Patent. Dependent

claims include all the limitations of the independent

claim (Claim 1), plus the added limitation described in

the dependent claim. “A claim in dependent form shall

be construed to incorporate by reference all the

limitations of the claim to which it refers.” 35 U.S.C. §

112(4). 3

Considering the parties’ submissions, the arguments at the Markman hearing, and given the above

standards, the Court makes these constructions:

Because the ’431 Patent was filed before the adoption of the

Leahy-Smith America Invents Act, Pub. L. No. 112-29, § 4(e), the

previous version of § 112 governs. See AbbVie Deutschland GmbH

& Co. v. Janssen Biotech, Inc., 759 F.3d 1285, 1290, n.3 (Fed. Cir.

2014).

WhereverTV asserts plain and ordinary meaning and also

proposes what the jury understands. (Doc. 165 at 39:9-40:19).

Counsel explained that if the term is given its plain and ordinary

meaning no jury instruction is needed. (Doc. 165 at 112:14-18).

The Court makes no determination at this time how the jury will

be instructed.

54a

To promote clarity, a patent specification must

“conclude with one or more claims particularly

pointing out and distinctly claiming the subject matter

which the applicant regards as his invention.”

35 U.S.C. § 112(2). This “definiteness” requirement

mandates that “a patent’s claims, viewed in light of the

specification and prosecution history, [must] inform

those skilled in the art about the scope of the invention

with reasonable certainty.” Nautilus, Inc. v. Biosig

Instruments, Inc., 572 U.S. 898, 910 (2014). “If a claim

employs a term of degree, the intrinsic record must

provide those skilled in the art with ‘objective

boundaries’ with which to assess the term’s scope.” In

re Walter, 693 F. App’x 1022, 1026 (Fed. Cir. 2017)

(quoting Interval Licensing LLC v. AOL, Inc., 766 F.3d

1364, 1371 (Fed. Cir. 2014) (addressing indefiniteness

in claim construction)). Terms of degree are not inherently indefinite. Interval Licensing, 766 F.3d at 1370.

Patents are presumed valid under 35 U.S.C. § 282,

so “[a]ny fact critical to a holding of indefiniteness . . .

must be proven by the challenger by clear and

convincing evidence.” Cox Commc’ns, Inc. v. Sprint

Commc’n Co. LP, 838 F.3d 1224, 1228 (Fed. Cir. 2016)

(quoting Intel Corp. v. VIA Techs., Inc., 319 F.3d 1357,

1366 (Fed. Cir. 2003)).

It is admittedly a close question whether the term

“only or virtually entirely streaming video programming” fails for indefiniteness. The claim term was

added during the patent prosecution (Doc. 94-5), but at

the oral argument WhereverTV offered no clear

indication what issue the claim term was intended to

resolve. Even so, the Court believes these words can be

understood by those skilled in the art, particularly

since Comcast itself was able to propose a construction

for term 5, which contains the same language. Thus, at

55a

this stage, the Court finds that Comcast has not met

its burden to show by clear and convincing evidence

that the term fails for indefiniteness under 35 U.S.C.

§ 112.

IV. SUPPLEMENT THE RECORD

WhereverTV requests that the Court consider

arguments made in its Motion to Supplement the

Record (Doc. 133) and supplement the claim construction record with a supplemental appendix containing the parties’ briefing before the Patent Trial &

Appeal Board (PTAB) and the PTAB’s two decisions

(Doc. 133-1). Comcast does not object to admitting

the supplemental appendix but does object to the

procedural and substantive arguments in Plaintiff’s

Motion to Supplement. (Doc. 160 ¶ 5). Without

objection, the Court will supplement the claim

construction record with the supplemental appendix

(Doc. 133-1).

V. CONCLUSION

As stated in a previous Order (Doc. 164, n.1), the

Court will reestablish discovery and other deadlines

and will take up consideration of the Motion to Compel

(Doc. 137) and the Motion to Quash (Doc. 148). (Doc.

164). Although the Court’s Markman rulings could

affect the parties’ positions on deadlines and the

pending discovery motions, the Court will let the

assigned Magistrate Judge address those issues.

Accordingly, it is hereby ORDERED:

1. Absent further order, further proceedings will

be consistent with this Order.

2. Plaintiff’s Motion for Leave to Supplement the

Claim Construction Record Based on New Evidence

(Doc. 133) is GRANTED to the extent the Court admits

the supplemental appendix (Doc. 133-1) into the claim

construction record.

3. Based on this Order and the status report

(Doc. 169) filed by the parties the assigned Magistrate

58a

Judge will set a schedule for remaining case events.

Now that Judge Badalamenti has assumed the Fort

Myers docket, this case will be transferred to him for

all future proceedings. Once the record is more fully

developed, Judge Badalamenti is free to revisit any of

these rulings as he sees fit.

4.

The Clerk is directed to re-open the case.
