UNITED STATES DISTRICT COURT
FOR THE DISTRICT OF NEW JERSEY

TOBII TECHNOLOGY, INC.,

Plaintiff,

v.
Case No. 2:20-cv-08062 (BRM) (JSA)
LEE S. WEINBLATT,

Defendant. OPINION

MARTINOTTI, DISTRICT JUDGE
Before this Court is a Motion to Dismiss filed by Plaintiff Tobii Technology, Inc. (“Tobii”)
seeking to dismiss a Counterclaim filed by Defendant Lee S. Weinblatt’s (“Weinblatt”) pursuant
to Federal Rule of Civil Procedure 12(b)(6). (ECF No. 20.) Weinblatt opposed the motion. (ECF
No. 26.) Tobii replied. (ECF No. 27.) Having reviewed the submissions filed in connection with
the motion and having declined to hold oral argument pursuant to Federal Rule of Civil Procedure
78(b), for the reasons set forth below and for good cause appearing, Tobii’s Motion to Dismiss is
GRANTED in part and DENIED in part.
I. BACKGROUND
For the purposes of this Motion to Dismiss, the Court “accept[s] as true all factual
allegations in the [Counterclaim] and draw[s] all inferences from the facts alleged in the light most
favorable to” Weinblatt. Phillips v. Cnty. of Allegheny, 515 F.3d 224, 228 (3d Cir. 2008) (citing
Worldcom, Inc. v. Graphnet, Inc., 343 F.3d 651, 653 (3d Cir. 2003)). Furthermore, the Court also
considers any “document integral to or explicitly relied upon in the complaint.” In re Burlington
Coat Factory Secs. Litig., 114 F.3d 1410, 1426 (3d Cir. 1997) (citing Shaw v. Dig. Equip. Corp.,
82 F.3d 1194, 1220 (1st Cir. 1996)).
Weinblatt is an inventor in the field of eye movement technology. (ECF No. 26 at 9.)
Weinblatt is the holder of U.S. Patent No. 7,641,341 B2 (the “’341 Patent”), which was issued on

January 5, 2010. (ECF No. 9-1 at 2.) The ’341 Patent covers an improved method and apparatus
for measuring a viewer’s saccadic eye motion (or saccade), as an indicator of the level of the
viewer’s interest in a visual stimulus such as an advertisement. (ECF No. 26 at 11–12.) Weinblatt
alleges Tobii manufactures and sells products that are covered by one or more claims of the ’341
Patent. (Id. at 9–10.)
On July 1, 2020, Tobii filed a Complaint against Weinblatt, seeking a declaratory judgment
that Tobii is not infringing and has not infringed the ’341 Patent. (ECF No. 1.) On November 11,
2020, Weinblatt filed a Counterclaim alleging infringement by Tobii of the ’341 Patent. (ECF No.
9 at 22–29.) The Counterclaim asserts infringement of claims 1, 3–7, 10–11, 13–14, 16–20, 23–
24, and 26 of the ’341 Patent (the “Asserted Claims”). (Id. at 25.) On December 16, 2020, Tobii

filed a Motion to Dismiss with prejudice Weinblatt’s Counterclaim, seeking to invalidate the
Asserted Claims under 35 U.S.C. §§ 101 and 112, ¶¶ 2 & 6.1 (ECF No. 20.) On January 18, 2021,
Weinblatt opposed the motion, defending the validity of the ’341 Patent under § 101 (patent subject
matter eligibility) and § 112 (definiteness). (ECF No. 26.) On January 25, 2021, Tobii filed a
Reply. (ECF No. 27.)
II. LEGAL STANDARD

1 Paragraph 2 and Paragraph 6 of 35 U.S.C. § 112 were replaced by § 112(b) and § 112(f)
respectively when the Leahy-Smith America Invents Act (“AIA”), Pub. L. No. 112-29, 125 Stat.
284 (2011) took effect on September 16, 2012. Because the application resulting in the ’341 Patent
was filed before that date, the Court refers to the pre-AIA version of § 112.
In deciding a motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(6), a
district court is “required to accept as true all factual allegations in the complaint and draw all
inferences in the facts alleged in the light most favorable to the [plaintiff].” Phillips, 515 F.3d at
228 (citing Worldcom, 343 F.3d at 653). “[A] complaint attacked by a Rule 12(b)(6) motion to

dismiss does not need detailed factual allegations.” Bell Atlantic Corp. v. Twombly, 550 U.S. 544,
555 (2007) (citations omitted). However, the plaintiff’s “obligation to provide the ‘grounds’ of his
‘entitle[ment] to relief’ requires more than labels and conclusions, and a formulaic recitation of
the elements of a cause of action.” Id. (citing Papasan v. Allain, 478 U.S. 265, 286 (1986)). A
court is “not bound to accept as true a legal conclusion couched as a factual allegation.” Papasan,
478 U.S. at 286 (citations omitted). Instead, assuming the factual allegations in the complaint are
true, those “[f]actual allegations must be enough to raise a right to relief above the speculative
level.” Twombly, 550 U.S. at 555 (citing 5 C. Wright & A. Miller, Federal Practice and Procedure
§ 1216, pp 235–36 (3d ed. 2004)).
“To survive a motion to dismiss, a complaint must contain sufficient factual matter,

accepted as true, to ‘state a claim for relief that is plausible on its face.’” Ashcroft v. Iqbal, 556
U.S. 662, 678 (2009) (quoting Twombly, 550 U.S. at 570). “A claim has facial plausibility when
the pleaded factual content allows the court to draw the reasonable inference that the defendant is
liable for misconduct alleged.” Id. (citing Twombly, 550 U.S. at 556). This “plausibility standard”
requires the complaint to allege “more than a sheer possibility that a defendant has acted
unlawfully,” but it “is not akin to a probability requirement.” Id. (quoting Twombly, 550 U.S. at
556). “Detailed factual allegations” are not required, but “more than an unadorned, the defendant-
harmed-me accusation” must be pled; it must include “further factual enhancement” and not just
conclusory statements or a recitation of the elements of a cause of action. Id. (citing Twombly, 550
U.S. at 555, 557).
“Determining whether a complaint states a plausible claim for relief [is] . . . a context-
specific task that requires the reviewing court to draw on its judicial experience and common

sense.” Id. at 679. “[W]here the well-pleaded facts do not permit the court to infer more than the
mere possibility of misconduct, the complaint has alleged—but it has not ‘show[n]’—‘that the
pleader is entitled to relief.’” Id. (quoting Fed. R. Civ. P. 8(a)(2)). However, courts are “not
compelled to accept ‘unsupported conclusions and unwarranted inferences,’” Baraka v.
McGreevey, 481 F.3d 187, 195 (3d Cir. 2007) (quoting Schuylkill Energy Res. Inc. v. Pa. Power
& Light Co., 113 F.3d 405, 417 (3d Cir. 1997)), nor “a legal conclusion couched as a factual
allegation.” Papasan, 478 U.S. at 286 (citations omitted).
While, as a general rule, the court may not consider anything beyond the four corners of
the complaint on a motion to dismiss pursuant to Rule 12(b)(6), the Third Circuit has held that “a
court may consider certain narrowly defined types of material without converting the motion to

dismiss to a summary judgment motion, including items that are integral to or explicitly relied
upon in the complaint.” Coulter v. Doerr, 486 F. App’x 227, 228 (3d Cir. 2012) (citing In re
Rockefeller Ctr. Props. Sec. Litig., 184 F.3d 280, 287 (3d Cir. 1999)).
III. DECISION
A. Tobii’s Motion to Dismiss Is Denied on the § 101 Issue
Tobii argues the Asserted Claims are directed to the abstract idea of displaying a stimulus
(e.g., a commercial) together with monitored information relating to the stimulus. (ECF No. 20-1
at 35.) Tobii maintains the core of the ’341 Patent, independent claim 1, recites a method that
exposes (i.e., displays), monitors (i.e., collect), and displays information; therefore, it is of a purely
functional nature and is not directed to a concrete embodiment of an idea. (Id. at 35–36.) Tobii
contends what is claimed in the ’341 Patent is not actively “determining” the viewer’s interest but
“displaying” information as an indication of a viewer’s interest, which only represents the purpose
or result of “displaying” and does not change the abstract nature of the claims. (ECF No. 27 at 10.)

Tobii asserts the ’341 Patent only uses well-known components and therefore is not a technological
improvement. (Id. at 11.)
Weinblatt counters the ’341 Patent is targeted at a technological improvement in the
method and apparatus for determining the effectiveness of an advertisement, by focusing on the
measurement of saccades, not fixations, to determine a viewer’s level of interest in advertisements
or specific portions thereof. (ECF No. 26 at 15–16.) Weinblatt explains claim 1 of the ’341 Patent
is not directed to a mere abstract idea, because it addresses a technological problem—determining
a viewer’s level of interest based on the saccadic information—that arises only in the computer
context, with no manual or pen-and-paper equivalent. (Id. at 16.) Weinblatt states the technology
underlying the ’341 Patent does not merely collect information, but changes the character of the

information by measuring tiny, fast saccadic movements of an eye and using that to determine the
level of interest of a viewer in certain aspects of an advertisement. (Id. at 25–26.) The Court
declines to make a decision on the § 101 issue at this stage.
The analysis under 35 U.S.C. § 101 follows the two-step process articulated in Alice Corp.
Pty. Ltd. v. CLS Bank Int’l to determine whether the patent claims at issue recite a patent-eligible
subject matter: (1) “whether the claims at issue are directed to one of those patent-ineligible
concepts,” such as “laws of nature, natural phenomena, and abstract ideas;” and (2) if so, whether
“an element or combination of elements” in each claim contains an “inventive concept” which is
“sufficient to ensure that the patent in practice amounts to significantly more than a patent upon
the ineligible concept itself.” 573 U.S. 208, 217–18 (2014) (citing Mayo Collaborative Servs. v.
Prometheus Labs., Inc., 566 U.S. 66 (2012)). “[T]he first-stage inquiry [] look[s] at the focus of
the claims,” i.e., “their character as a whole.” Elec. Power Grp., LLC v. Alstom S.A., 830 F.3d
1350, 1353 (Fed. Cir. 2016) (citations omitted). “If the claims are not directed to an abstract idea,

the inquiry ends.” RecogniCorp, LLC v. Nintendo Co., 855 F.3d 1322, 1326 (Fed. Cir. 2017) (citing
Thales Visionix Inc. v. United States, 850 F.3d 1343, 1349 (Fed. Cir. 2017)). Otherwise, the court
should proceed to step two of the Alice analysis to determine whether “the claimed elements—
‘individually and as an ordered combination’—recite an inventive concept.” Cellspin Soft, Inc. v.
Fitbit, Inc., 927 F.3d 1306, 1316 (Fed. Cir. 2019) (quoting Alice, 573 U.S. at 217). This analysis
entails “whether the combination of elements was well-understood, routine, and conventional at
the time of the invention.” Exergen Corp. v. Kaz USA, Inc., 725 F. App’x 959, 963 (Fed. Cir. 2018).
Claims of patent infringement should be dismissed under Rule 12(b)(6) if the “asserted
patents are invalid as patent-ineligible under § 101.” Content Extraction & Transmission LLC v.
Wells Fargo Bank, N.A., 776 F.3d 1343, 1351 (Fed. Cir. 2014). In applying § 101 at the pleading

stage, a court “will address the claims [at issue] as preventing a motion to dismiss and will construe
those patent claims in ‘the manner most favorable’ to [nonmovants].” Scibetta v. Slingo, Inc., Civ.
A. No. 16-8175, 2018 U.S. Dist. LEXIS 7826, at *17, 22 n.3 (D.N.J. Jan. 17, 2018) (denying the
defendant’s motion to dismiss the plaintiffs’ patent infringement case and rejecting the defendant’s
argument that the patents at issue were “directed at a patent-ineligible subject matter” (citing id. at
1348)); see also Athena Diagnostics, Inc. v. Mayo Collaborative Servs., LLC, 275 F. Supp. 3d 306,
308 (D. Mass. 2017), aff’d, 915 F.3d 743 (Fed. Cir. 2019) (“In applying § 101 at the pleading
stage, the court construes the patent claims in a manner most favorable to the non-moving party.”
(citing Content Extraction, 776 F.3d at 1349)). The same standard applies when a “Rule 12(b)(6)
[m]otion is used to assert an affirmative defense—that the patents are subject matter ineligible
under Section 101.” M2M Sols. LLC v. Amazon.com, Inc., Civ. A. No. 17-202, 2017 U.S. Dist.
LEXIS 203110, at *5 (D. Del. Dec. 11, 2017) (“[D]ismissal is permitted only if the well-pleaded
factual allegations in the [c]omplaint, construed in the light most favorable to the plaintiff, suffice

to establish the defense.” (citations omitted)).
Therefore, to succeed on its motion to dismiss, it is not enough for Tobii to just present a
legal theory that suggests the Asserted Claims are directed to an abstract idea. Instead, Tobii “bears
the burden of showing that no claim has been presented.” Mendez v. Shah, 28 F. Supp. 3d 282, 288
(D.N.J. 2014) (quoting Hedges v. United States, 404 F.3d 744, 750 (3d Cir. 2005)). That is, on the
§ 101 issue, Tobii must demonstrate the Asserted Claims, even if construed in a manner most
favorable to Weinblatt, are directed to an abstract idea. Because Weinblatt invoked the pen-and-
paper test in response to Tobii’s argument that the Asserted Claims are directed to an abstract idea,
Tobii must establish, in accordance with his “ultimate burden of proving [patent] infringement,”
Novartis Corp. v. Ben Venue Labs., Inc., 271 F.3d 1043, 1046 (Fed. Cir. 2001) (citations omitted),

that the pen-and-paper test either does not apply to the Asserted Claims or cannot show the
Asserted Claims are not directed to an abstract idea.
“The ‘pen and paper’ framework is . . . useful [] in determining whether [] patents are
directed at an abstract idea.” Open Parking, LLC v. ParkMe, Inc., Civ. A. No. 15-976, 2016 U.S.
Dist. LEXIS 85260, at *20 (W.D. Pa. June 30, 2016). “[A] claim whose ‘steps can be performed
in the human mind, or by a human using a pen and paper’ is directed to an ‘unpatentable mental
process[].’” BSG Tech LLC v. Buyseasons, Inc., 899 F.3d 1281, 1286 (Fed. Cir. 2018) (quoting
CyberSource Corp. v. Retail Decisions, Inc., 654 F.3d 1366, 1372–73 (Fed. Cir. 2011)); see also
ENCO Sys. v. DaVincia, LLC, 845 F. App’x 953, 957 (Fed. Cir. 2021) (“[C]laims focused just on
replacing ‘pen and paper methodologies’ with ‘data synthesis technology’—without a focus on
specific, assertedly improved processing techniques—[are] directed to an abstract idea.” (quoting
Univ. of Fla. Research Found., Inc. v. Gen. Elec. Co., 916 F.3d 1363, 1367 (Fed. Cir. 2019)));
NantWorks, LLC v. Niantic, Inc., Civ. A. No. 20-6262, 2021 U.S. Dist. LEXIS 487, at *10–11

(N.D. Cal. Jan. 4, 2021) (“[I]f a process can be performed in other ways—mentally, or by putting
pen to paper—it is an abstract idea.” (citing Synopsys, Inc. v. Mentor Graphics Corp., 839 F.3d
1138, 1147 (Fed. Cir. 2016))). “‘[C]laiming the improved speed or efficiency inherent with
applying the abstract idea on a computer’ [is] insufficient to render the claims patent eligible.”
ENCO Sys., 845 F. App’x at 957 (quoting Customedia Techs., LLC v. Dish Network Corp., 951
F.3d 1359, 1364 (Fed. Cir. 2020)). Conversely, a claim is likely not directed to an abstract idea if
it covers a task that a human cannot perform with a pen and paper. See Linksmart Wireless Tech.,
LLC v. Caesars Entm’t Corp., Civ. A. No. 18-862, 2019 U.S. Dist. LEXIS 220543, at *13–14 (D.
Nev. Dec. 23, 2019) (finding that the claims at issue “were directed to more than an abstract idea,”
in part because they reflected “more than a mental process easily done with pen and paper”

(citations omitted)); Confident Techs., Inc. v. AXS Grp. LLC, Civ. A. No. 17-2181, 2018 U.S. Dist.
LEXIS 10949, at *16–17 (S.D. Cal. Jan. 23, 2018) (finding that “[d]efendants [] failed to establish
that the [patent at issue] [wa]s directed to an abstract idea,” in part because “[d]efendants fail[ed]
to adequately explain how a human with a pencil and paper could administer the claimed” activity);
InfoGation Corp. v. ZTE Corp., Civ. A. No. 16-1901, 2017 U.S. Dist. LEXIS 44873, at *18–19
(S.D. Cal. Mar. 27, 2017) (finding that a claim was “directed to a specific improvement to an
existing technological process rather than an abstract idea,” because “a human with a pencil and
paper cannot” perform the claimed improvement).
Here, Weinblatt suggests a human cannot perform the activity covered by the ’341 Patent,
i.e., measuring saccades. (ECF No. 26 at 27.) Tobii does not dispute this factual position and offers
no reason why the pen-and-paper test is inapplicable here.2 Therefore, there is a factual question
concerning whether a human can perform with a pen and paper the activity covered by the ’341
Patent. In other words, there is a factual question concerning whether the Asserted Claims are

directed to an abstract idea. The Asserted Claims may not necessarily fail Alice step one.
Even if the pen-and-paper test “is not dispositive and is only one test to determine if a claim
is directed to an abstract idea,” Affinity Labs of Tex., LLC v. Amazon.com, Inc., Civ. A. No. 15-29,
2015 U.S. Dist. LEXIS 77411, at *29 (W.D. Tex. June 12, 2015), aff’d, 838 F.3d 1266 (Fed. Cir.
2016) (citing Alice, 573 U.S. at 219–20), the Court must apply the test in a manner most favorable
to Weinblatt. That is, the pen-and-paper test creates a factual question sufficient for Weinblatt to
survive Tobii’s Motion to Dismiss on the § 101 issue. See Capstan AG Sys. v. Raven Indus., Inc.,
228 F. Supp. 3d 1235, 1245 n.9 (D. Kan. 2017) (denying the defendant’s motion to dismiss the
plaintiff’s patent infringement case, though “[d]efendants interpret[ed] the claimed systems and
methods as ones consisting of nothing more than actions that a human being could do with pencil

and paper,” because the court found “the [c]omplaint and patents [at issue] d[id] not answer this
potentially outcome-determinative question” on the pen-and-paper test and therefore needed
“more evidence than it can consider at the motion to dismiss stage” (citations omitted)); Card
Verification Sols., LLC v. Citigroup Inc., Civ. A. No. 13-6339, 2014 U.S. Dist. LEXIS 137577, at
*11–12 (N.D. Ill. Sept. 29, 2014) (denying the defendant’s motion to dismiss the plaintiff’s patent
infringement case, because whether a method covered by the patent at issue, alleged by the

2 As for the pen-and-paper test, Tobii only argues it “is one of several approaches to determining
if a claim is abstract, but not one upon which Tobii relies.” (ECF No. 27 at 12 n.10.) This does not
negate the applicability of the test here.
defendant to be an abstract idea, “c[ould] be performed by a human with nothing more than pen
and paper pose[d] a factual question inappropriate at the motion to dismiss stage”).
Interestingly, Weinblatt cites a California case that found the pen-and-paper test not
“helpful” where the subject of the claim is “not conventional activity that humans engaged in

before computers.” (ECF No. 26 at 28 (citing Cal. Inst. of Tech. v. Hughes Commc’ns Inc. (“CIT”),
59 F. Supp. 3d 974, 995 (C.D. Cal. 2014) (finding that the “[p]encil-and-paper analysis is
inappropriate” where the claim at issue does not cover a “conventional activity that humans
engaged in before computers”)).) Further, Weinblatt admits “the problem of determining a level
of interest based on saccadic information arises only in the computer data context with high speed
cameras and processors and has no manual equivalent whatsoever.” (Id. at 29.) In other words,
Weinblatt admits the activity covered by the ’341 Patent is not a conventional activity that humans
engaged in before computers. Under CIT, Weinblatt’s admission would mean the pen-and-paper
test is inapplicable here. However, the Court declines to follow CIT, which does not bind this
Court. Moreover, CIT’s potential exception to the pen-and-paper test has not been adopted by the

United States Court of Appeals for the Federal Circuit (the “Federal Circuit”) or any court in the
Third Circuit. As a result, the Court still considers the pen-and-paper test relevant in the Alice step
one analysis here.
Construing the Asserted Claims in a manner most favorable to Weinblatt, the Court
declines to conclude, at this stage, the Asserted Claims are directed to an abstract idea.
Accordingly, Tobii’s Motion to Dismiss is DENIED on the § 101 issue as to all the Asserted
Claims.
B. Tobii’s Motion to Dismiss Is Granted on the § 112 Issue
The parties agree claim 14 of the ’341 Patent is drafted in a “means-plus-function” format
under § 112. (ECF No. 20-1 at 45; ECF No. 26 at 36.) The parties dispute whether there is adequate
corresponding structure disclosed in the ’341 Patent for claim 14’s claimed function of “displaying
the visual stimuli together with the monitored saccadic eye motion that occurred while the viewer
was being exposed to the visual stimuli as an indication of the viewer’s interest in such visual

stimuli” (the “Claimed Function”). (ECF No. 20-1 at 45–46; ECF No. 26 at 36–37.) This disputed
point will be addressed below.
“Indefiniteness is a question of law.” Amgen Inc. v. F. Hoffmann-La Roche, Ltd., 580 F.3d
1340, 1371 (Fed. Cir. 2009) (citing Praxair, Inc. v. ATMI, Inc., 543 F.3d 1306, 1319 (Fed. Cir.
2008)). “If a claim fails to reasonably apprise one skilled in the art of the boundaries of the claim
when read in light of the specification, then the claim is invalid under § 112 for indefiniteness.”
Id. (citing Miles Lab., Inc. v. Shandon, Inc., 997 F.2d 870, 875 (Fed. Cir. 1993)). Under § 112,
“[t]he specification shall 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.
“Claim limitations drafted pursuant to 35 U.S.C. § 112, [¶] 6 are termed means-plus-

function limitations.” Mas-Hamilton Grp. v. LaGard, Inc., 156 F.3d 1206, 1211 (Fed. Cir. 1998).
“An element in a claim for a combination may be expressed as a means or step for performing a
specified function without the recital of structure . . . in support thereof, and such claim shall be
construed to cover the corresponding structure . . . described in the specification and equivalents
thereof.” 35 U.S.C. § 112, ¶ 6. “Once a court concludes that a claim limitation is a means-plus-
function limitation, two steps of claim construction remain: 1) the court must first identify the
function of the limitation; and 2) the court must then look to the specification and identify the
corresponding structure for that function.” Biomedino, LLC v. Waters Techs. Corp., 490 F.3d 946,
950 (Fed. Cir. 2007). “[I]n order for a means-plus-function claim to be valid under § 112, the
corresponding structure of the limitation ‘must be disclosed in the written description in such a
manner that one skilled in the art will know and understand what structure corresponds to the
means limitation.’” Id. (quoting Atmel Corp. v. Information Storage Devices, 198 F.3d 1374, 1382
(Fed. Cir. 1999)).

1. Display Processor 9 Is a Part of the Corresponding Structure for the
Claimed Function

Tobii maintains the corresponding structure disclosed for the Claimed Function includes
Display Processor 9, Display Circuit 5, and Video Display 3.3 (ECF No. 20-1 at 45.) Tobii insists
Display Processor 9 is a part of the corresponding structure, because it provides the signal for the
monitored saccadic eye motion as referred to the Claimed Function, while Display Circuit 5 and
Video Display 3 are unable to provide that signal. (ECF No. 27 at 17.) Weinblatt argues performing
the Claimed Function only requires Display Circuit 5 and Video Display 3, which the parties agree
are admitted, well known structures. (ECF No. 20-1 at 45; ECF No. 26 at 37.) The Court disagrees
with Weinblatt.
“While corresponding structure need not include all things necessary to enable the claimed
invention to work, it must include all structure that actually performs the recited function.” Default
Proof Credit Card Sys., Inc. v. Home Depot U.S.A., Inc., 412 F.3d 1291, 1298 (Fed. Cir. 2005)
(citing Cardiac Pacemakers, Inc. v. St. Jude Med., Inc., 296 F.3d 1106, 1119 (Fed. Cir. 2002)).
Here, claim 14’s plain language shows the Claimed Function includes at least three functional
elements: (1) “displaying;” (2) “together with . . . while;” and (3) “as an indication of.” The first

3 Display Processor 9, Display Circuit 5, and Video Display 3 are different components in the
drawing provided in the ’341 Patent that depicts a schematic block diagram of a system for
implementing an exemplary embodiment of the invention. (ECF No. 9-1 at 3; ECF No. 20-1 at
15.)
element means the display of two signals, i.e., the visual stimuli and the viewer’s saccades
triggered by the visual stimuli, which are (at least in part) performed by Display Circuit 5 and
Video Display 3. The second element means displaying the two signals together and
simultaneously.4 The third element refers to the ability of such signal display to indicate the

viewer’s interest in the visual stimuli.
Display Processor 9 is involved in actually performing the third element. The ’341 Patent’s
specification provides: “the level of viewer interest in a particular image is regarded as being
related to the number of saccades . . . that occurs during a given period of time.” (ECF No. 9-1 at
4:42–45.) Display Processor 9 helps indicate the level of viewer interest in at least two ways. First,
it “includes an internal clock . . . which can be used to set a selected measurement time period.”
(Id. at 4:48–50.) “A reading is obtained of whatever number of [saccadic] oscillations occur during
that given time period.” (Id. at 4:50–52.) With this, Display Processor 9 is involved in producing
the readings, i.e., the raw data, which indicate the viewer’s interest. Second, Display Processor 9
“converts such readings into data suitable for the particular way in which such information is to

be displayed,” such as “a number superimposed on the program being reproduced on [Video]
[D]isplay 3.” (Id. at 4:52–56.) With this, Display Processor 9 produces the displayable data that
indicate the viewer’s interest. In contrast, Display Circuit 5 and Video Display 3 are not involved
in the above processes that provide for the ability to indicate a viewer’s interest. Therefore, Display
Processor 9 is a part of the corresponding structure for the Claimed Function and must be disclosed
in the specification.
2. The Disclosure for Display Processor 9 Is Inadequate for Lacking Any
Algorithm

4 Notably, neither party addresses the corresponding structure for this second element, especially
Memory 11 that is responsible for time-synchronizing the two signals. (See ECF No. 9-1 at 4:22–
25.) As a result, the Court need not analyze the second element.
Tobii states the ’341 Patent contains no description on how Display Processor 9 provides
for the ability to perform the Claimed Function: the ’341 Patent only discloses that Display
Processor 9 converts the reading of the number of saccades occurring in a given time period to a
displayable signal, but provides no algorithm to show how Display Processor 9 should be
programmed and no explanation on how the conversion process is done. (ECF No. 20-1 at 45–46;
ECF No. 27 at 18.) Tobii maintains Display Processor 9 is a general-purpose microprocessor that
cannot perform the Claimed Function without special programming, which necessitates the
disclosure of an underlying algorithm. (ECF No. 20-1 at 47.) Tobii adds, the algorithm must be
disclosed in a degree of detail such that a person having ordinary skill in the art (“POSA”) would

know how to program the microprocessor to achieve the Claimed Function. (Id.) Tobii contends
claim 14 is indefinite, because the ’341 Patent does not describe any algorithm in any form
accompanying or explaining the Claimed Function. (Id. at 48.)
Weinblatt asserts the ’341 Patent provides sufficient definiteness with respect to Display
Processor 9. (ECF No. 26 at 38.) Weinblatt explains Display Processor 9 is described as a processor
with an internal clock to measure saccades over a period of time and convert those measurements
into displayable data. (Id. at 39.) Weinblatt stresses a specific algorithm need not be disclosed to
avoid indefiniteness where the function in question would be readily apparent to a POSA. (Id.)
Weinblatt posits, whether a POSA would identify the corresponding structure and whether the

disclosure of the corresponding structure is sufficiently definite to a POSA are issues inappropriate
for resolution at the pleading stage; instead, these issues should be decided as part of the claim
construction process with expert testimony. (Id. at 45.) The Court disagrees.
To have a valid means-plus-function claim, “the patent specification must disclose with
sufficient particularity the corresponding structure for performing the claimed function and clearly
link that structure to the function.” Nevro Corp. v. Boston Sci. Corp., 955 F.3d 35, 42 (Fed. Cir.
2020) (citing Ibormeith IP, LLC v. Mercedes-Benz USA, LLC, 732 F.3d 1376, 1379 (Fed. Cir.
2013)). “[I]f a patentee has invoked computer-implemented means-plus-function claiming, the
corresponding structure in the specification for the computer implemented function must be an

algorithm unless a general purpose computer is sufficient for performing the function.” Apple Inc.
v. Motorola, Inc., 757 F.3d 1286, 1298 (Fed. Cir. 2014) (citations omitted); see also EON Corp.
IP Holdings LLC v. AT&T Mobility LLC, 785 F.3d 616, 623 (Fed. Cir. 2015) (“A microprocessor
or general purpose computer lends sufficient structure only to basic functions of a microprocessor.
All other computer-implemented functions require disclosure of an algorithm.”). “Failure to
disclose the corresponding algorithm for a computer-implemented means-plus-function term
renders the claim indefinite.” Triton Tech of Tex., LLC v. Nintendo of Am., Inc., 753 F.3d 1375,
1378 (Fed. Cir. 2014) (citing Ergo Licensing LLC v. CareFusion 303, Inc., 673 F.3d 1361, 1363
(Fed. Cir. 2012)). Therefore, “in a means-plus-function claim ‘in which the disclosed structure is
a computer, or microprocessor, programmed to carry out an algorithm, the disclosed structure is

not the general purpose computer, but rather the special purpose computer programmed to perform
the disclosed algorithm.’” Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1367 (Fed. Cir.
2008) (quoting Aristocrat Techs. Austl. Pty Ltd. v. Int’l Game Tech., 521 F.3d 1328, 1333 (Fed.
Cir. 2008)).
Here, it is undisputed that Display Processor 9 is a computer or microprocessor, which
triggers the algorithm disclosure requirement. The Court does not discern, and Weinblatt does not
allege, the function of Display Processor 9 “can be achieved by any general purpose computer
without special programming” so as to qualify for “a narrow exception to” the algorithm disclosure
requirement. Ergo, 673 F.3d at 1364–65 (quoting In re Katz Interactive Call Processing Patent
Litig., 639 F.3d 1303, 1316 (Fed. Cir. 2011)). Instead, as discussed in Part III.B.1, supra, Display
Processor 9 performs the Claimed Function by including an internal clock that can set a selected
measurement time period for saccades. The selection of a specific measurement time period
involves “specific functions that would need to be implemented by programming a general purpose

computer to convert it into a special purpose computer capable of performing those specified
functions.” Katz, 639 F.3d at 1316 (citations omitted). Such specific functions are more than
merely “‘processing,’ ‘receiving,’ and ‘storing,’ [which] can be achieved by any general purpose
computer without special programming.” Id. Therefore, an algorithm must be disclosed to explain
the performance of the Claimed Function by Display Processor 9.
An algorithm is broadly defined as “a step-by-step procedure for solving a problem” or
“accomplishing a given result.” Intellectual Ventures I, LLC v. AT&T Mobility, LLC, Civ. A. No.
12-193, 2015 U.S. Dist. LEXIS 36546, at *37 (D. Del. Mar. 24, 2015) (quoting Typhoon Touch
Techs., Inc. v. Dell, Inc., 659 F.3d 1376, 1384–85 (Fed. Cir. 2011)). “An algorithm may be
expressed ‘in any understandable terms including as a mathematical formula, in prose, or as a flow

chart, or in any other manner that provides sufficient structure.’” Ergo, 673 F.3d at 1365 (quoting
Typhoon, 659 F.3d at 1385). “Even described ‘in prose,’ an algorithm is still ‘a step-by-step
procedure for accomplishing a given result.’” Id. (quoting Typhoon, 659 F.3d at 1385). The Court
does not discern, and Weinblatt does not point to, any algorithm for Display Processor 9 in the
’341 Patent. Weinblatt alleges the following description in the specification is a sufficient
disclosure: “The Display Processor 9 is described as a processor with an internal clock to measure
saccades over a period of time and convert those measurements into data suitable for display on
Video Display 3, such as through a number or bar graph.” (ECF No. 26 at 39.) However, the only
structural language in this description is “a processor with an internal clock,” which does not reflect
a step-by-step procedure and cannot qualify as an algorithm. The rest of the description contains
“purely functional language, which simply restates the function associated with the means-plus-
function limitation [and] is insufficient to provide the required corresponding structure.” Noah Sys.
Inc. v. Intuit Inc., 675 F.3d 1302, 1317 (Fed. Cir. 2012) (citations omitted). Therefore, the

description “[s]imply disclos[es] a black box that performs the recited function,” which “is not a
sufficient explanation of the algorithm required to render the means-plus-function term definite.”
Augme Techs., Inc. v. Yahoo! Inc., 755 F.3d 1326, 1338 (Fed. Cir. 2014) (finding the description
that “‘[c]ode assembler instructions’ are executed ‘to assemble a second code module’” was
“nothing more than a black box” (citing ePlus, Inc. v. Lawson Software, Inc., 700 F.3d 509, 518
(Fed. Cir. 2012))); see also In re TLI Communs. LLC Patent Litig., 87 F. Supp. 3d 773, 802 (E.D.
Va. 2015) (“[T]he corresponding structure accompanying a means-plus-function claim must
describe how a particular function is carried out, instead of merely disclosing an abstract structure
without further explanation.”).
The Court rejects Weinblatt’s argument that the disclosure of algorithms is not necessary

where, as here, the relevant algorithms may be readily apparent to a POSA. Indeed, some earlier
Federal Circuit decisions suggest a relaxation on the algorithm disclosure requirement when the
relevant algorithms are readily apparent to a POSA.5 However, these decisions only demonstrate

5 See, e.g., Aristocrat Techs. Austl. Pty Ltd. v. Multimedia Games, Inc., 266 F. App’x 942, 946
(Fed. Cir. 2008) (“The law does not require that structure be explicitly identified as long as a
person of ordinary skill in the art would understand what structure is identified in the
specification.” (citing Atmel, 198 F.3d at 1380)); Med. Instrumentation & Diagnostics Corp. v.
Elekta AB, 344 F.3d 1205, 1214 (Fed. Cir. 2003) (“[T]here would be no need for a disclosure of
the specific program code if software were linked to the converting function and one skilled in the
art would know the kind of program to use.”); In re Kullmann, 115 F.3d 942, 946 (Fed. Cir. 1997)
(finding that the written description at issue was sufficiently definite, even though “the written
description d[id] not disclose exactly what mathematical algorithm w[ould] be used to compute
the end result,” when “it d[id] state that ‘known algorithms’ c[ould] be used to solve standard
equations which [we]re known in the art”).
“the sufficiency of the disclosure of algorithmic structure must be judged in light of what one of
ordinary skill in the art would understand the disclosure to impart.” Aristocrat, 521 F.3d at 1333
(commenting on the cited portion of the Elekta opinion in footnote 5 (citations omitted)). Such a
relaxation of the algorithm disclosure requirement “has no application” if “there was no algorithm

at all disclosed in the specification.” Id. This position—i.e., a POSA’s potential knowledge of the
relevant algorithms cannot completely relieve the algorithm disclosure requirement—has been
repeatedly confirmed in a number of more recent Federal Circuit cases.6
Therefore, the disclosure with respect to Display Processor 9 is insufficient under § 112
for lacking any algorithm to explain its performance of the Claimed Function. Whether a relevant
algorithm is readily apparent to a POSA is irrelevant. “[S]ince it has been determined that no
algorithm has been disclosed at all, the Court [i]s not required to actually consider the parties’

6 See, e.g., Alfred E. Mann Found. for Sci. Research v. Cochlear Corp., 841 F.3d 1334, 1344 (Fed.
Cir. 2016) (“Although . . . a person of ordinary skill in the art would know of potential logarithmic
conversion functions to implement, this does not create structure in the patent where there was
none to begin with.” (citing Triton, 753 F.3d at 1379)); EON Corp., 785 F.3d at 623 (“[A] person
of ordinary skill in the art plays no role whatsoever in determining whether an algorithm must be
disclosed as structure for a functional claim element.”); Triton, 753 F.3d at 1379 (finding that the
patent at issue failed to satisfy the disclosure requirement under § 112, because “a bare statement
that known techniques or methods can be used does not disclose structure,” and “[a]lthough a
person of skill in the art might be able to choose an appropriate numerical integration algorithm
and program it onto a microprocessor, the patent discloses no algorithm at all” (citations omitted));
Function Media, L.L.C. v. Google Inc., 708 F.3d 1310, 1318 (Fed. Cir. 2013) (“When dealing with
a ‘special purpose computer-implemented means-plus-function limitation,’ we require the
specification to disclose the algorithm for performing the function . . . . While it is true that the
patentee need not disclose details of structures well known in the art, . . . the specification must
nonetheless disclose some structure.” (citations omitted)); Noah, 675 F.3d at 1313 (“Where no
structure appears, the question is . . . whether an algorithm was disclosed at all. When the
specification discloses some algorithm . . . the question is whether the disclosed algorithm, from
the viewpoint of a person of ordinary skill, is sufficient to define the structure and make the bounds
of the claim understandable.” (citations and internal quotation marks omitted)); Default Proof, 412
F.3d at 1302 (“[T]he testimony of one of ordinary skill in the art cannot supplant the total absence
of structure from the specification.”).

691 n.6 (D.N.J. 2012), aff’d, 732 F.3d 1376 (Fed. Cir. 2013) (citing Default Proof, 412 F.3d at
1302); see also Fortinet, Inc. v. Sophos, Inc., Civ. A. No. 13-5831, 2015 U.S. Dist. LEXIS 146317,
at *17 (N.D. Cal. Oct. 28, 2015) (“[E]xpert testimony can only ‘fill in the blanks’ where there is a

partially disclosed algorithm; it cannot be relied upon in the absence of any disclosure of an
algorithm.” (citing Noah, 675 F.3d at 1313)).
As a result, independent claim 14 of the ’341 Patent, which recites the Claimed Function
performed in part by Display Processor 9, is invalid for indefiniteness. The dependent claims
related to claim 14 “would also be invalid [for indefiniteness], because they incorporate the
elements of [the] independent claim.” Ibormeith, 732 F.3d at 1378; see also Blackboard, Inc. v.
Desire2Learn, Inc., 574 F.3d 1371, 1382 (Fed. Cir. 2009) (affirming the district court’s holding
that “the specification contained insufficient structure to support one of the means-plus-function
limitations found in claim 1 and, by incorporation, in dependent claims 2–35”). Accordingly,
Tobii’s Motion to Dismiss is GRANTED on the § 112 issue.

“The determination of the claimed function and corresponding structure of a means-plus-
function claim limitation is a question of law.” AllVoice Computing PLC v. Nuance Communs.,
Inc., 504 F.3d 1236, 1241 (Fed. Cir. 2007) (quoting ACTV, Inc. v. Walt Disney Co., 346 F.3d 1082,
1087 (Fed. Cir. 2003)); see also Pictometry Int’l Corp. v. Geospan Corp., Civ. A. No. 11-1423,
2012 U.S. Dist. LEXIS 116044, at *11 (D. Minn. Aug. 17, 2012) (“It is a question of law whether
the specification fails to disclose a corresponding structure and is, therefore, invalid for
indefiniteness pursuant to 35 U.S.C. § 112 ¶ 2.” (citing Cardiac Pacemakers, 296 F.3d at 1113));

patent is indefinite for failure to disclose a corresponding structure is a question of law.” (citing
Default Proof, 412 F.3d at 1298)). Therefore, the dismissal of Weinblatt’s Counterclaim on the §
112 issue as to claims 14, 16–20, 23–24, and 26 is WITH PREJUDICE. See Allen v. Quicken
Loans, Inc., Civ. A. No. 17-12352, 2018 U.S. Dist. LEXIS 192066, at *20 (D.N.J. Nov. 9, 2018)

following claims are dismissed with prejudice . . . because they are invalid as a matter of law.”).
IV. CONCLUSION
For the reasons set forth above, Tobii’s Motion to Dismiss is DENIED on the § 101 issue
and is GRANTED on the § 112 issue. Weinblatt’s Counterclaim is DISMISSED WITH
PREJUDICE as to claims 14, 16–20, 23–24, and 26 of the ’341 Patent. An appropriate order
follows.
