Before PROST, HUGHES, and STARK, Circuit Judges.

PROST, Circuit Judge.

Google LLC (“Google”) petitioned for inter partes re-

view (“IPR”) of claims 1–22 of U.S. Patent No. 10,869,169

(“the ’169 patent”). In a final written decision, the Patent

Trial and Appeal Board (“Board”) concluded that claims

1–14 and 16–22, but not claim 15, are unpatentable as ob-

vious. Google LLC v. Wildseed Mobile, LLC, No. IPR2023-

00247, Paper No. 33, 2024 WL 2819590 (P.T.A.B. June 3,

2024) (“Final Written Decision”). Google appeals the

Board’s determination that claim 15 is not unpatentable.

For the reasons set forth below, we vacate and remand.

BACKGROUND

I

Wildseed Mobile, LLC (“Wildseed”) is the owner of the

’169 patent. The ’169 patent is titled “Method and Systems

for Generating and Sending a Hot Link Associated with a

User Interface to a Device.” ’169 patent Title (capitaliza-

tion normalized). It relates to “generating and sending a

hot link to a device.” Id. at col. 1 ll. 66–67. “The hot link

contains an action that instructs the receiving device to

perform some activity when an associated user interface is

selected.” Id. at col. 1 l. 67–col. 2 l. 3. Claim 15 recites:

15. The computer system of claim 10, wherein the

processor circuitry is to:

generate the hot link message as a Short Message

Service (SMS) message for transmission over a cel-

lular communication network, or

Case: 24-2178 Document: 41 Page: 3 Filed: 02/13/2026

GOOGLE LLC v. WILDSEED MOBILE, LLC 3

generate the hot link message as an instant mes-

saging (IM) message for transmission over a com-

munications network.

Id. at claim 15 (emphasis added). Relevant to this ap-

peal, claim 15 thus recites two limitations—an SMS limi-

tation and an IM limitation—separated by “or.” Id.

II

In 2023, Google petitioned for IPR of claims 1–22 of the

’169 patent. For dependent claim 15, Google argued in its

petition that U.S. Patent No. 8,645,211 (“Rothschild”) dis-

closes the claim limitations. Google quoted language from

Rothschild and explained that “Rothschild describes its

technique with the example of an e-mail message, but

states that it is applicable to other forms of communication

including SMS messages and instant messages.” J.A. 115,

129. Wildseed’s sur-reply responded to Google’s claim 15

arguments. Wildseed acknowledged that “[Google’s] sole

allegations regarding SMS and IM are that Rothschild also

discloses those formats.” J.A. 477. Wildseed, however, con-

fined its arguments to the SMS limitation of claim 15, ar-

guing that Google never rebutted explanation by

Wildseed’s expert that “SMS messages do not use HTML

tags.” J.A. 477.

The Board determined claims 1–14 and 16–22, but not

claim 15, unpatentable for obviousness over various refer-

ences including Rothschild and U.S. Patent No. 6,836,792

(“Chen”). In addressing claim 15, the Board limited its

analysis to the SMS limitation and did not mention the IM

limitation. The Board noted that HTML code is relied upon

as teaching the rendering limitation in the independent

claims but “the record establishes that SMS does not use

HTML or any other formatting in sending a message.” Fi-

nal Written Decision, 2024 WL 2819590, at *15. The Board

determined that “[b]ecause SMS messages are not format-

ted, [Google] has not persuasively explained how a message

sent by SMS would satisfy the ‘instructions for rendering

Case: 24-2178 Document: 41 Page: 4 Filed: 02/13/2026

4 GOOGLE LLC v. WILDSEED MOBILE, LLC

and displaying the hot link’ recited in claim 10 that are in-

corporated into dependent claim 15.” Id. The Board ana-

lyzed Google’s alternate assertion that the image data “e.g.,

a JPEG file, informs the receiving device how to display the

image.” Id. The Board found that this assertion “is part of

the HTML embodiment that [Google] relies upon.” Id. at

*16. The Board determined that “[b]ecause [Google] does

not explain how an image displayed in an SMS would be

rendered” and Wildseed’s expert “attest[ed] that the ’169

patent does not apply formatting to the SMS message, . . .

[Google] has not persuasively shown that the data of the

image field itself provides the claimed instructions for dis-

playing and rendering.” Id.

The Board thus determined that “[Google] has not per-

suasively shown that Rothschild in view of Chen teaches

instructions for displaying and rendering where the hot

link message is generated as an SMS message as recited in

claim 15.” Id. The Board concluded that as a result,

“[Google] has not shown, by a preponderance of the evi-

dence, that claim 15 would have been obvious over Roth-

schild in view of Chen.” Id.

Google timely appeals. We have jurisdiction under

28 U.S.C. § 1295(a)(4)(A).

DISCUSSION

We review the Board’s decisions “under the standards

provided in the Administrative Procedure Act (‘APA’),

5 U.S.C. § 706.” Unwired Planet, LLC v. Google Inc.,

841 F.3d 1376, 1379 (Fed. Cir. 2016) (cleaned up). Under

the APA, the Board’s actions “are to be set aside if ‘arbi-

trary, capricious, an abuse of discretion, or otherwise not

in accordance with law’ or ‘unsupported by substantial ev-

idence.’” Pride Mobility Prods. Corp. v. Permobil, Inc.,

818 F.3d 1307, 1313 (Fed. Cir. 2016). “In order to provide

for effective judicial review, then, the Board is obligated to

‘provide an administrative record showing the evidence on

which the findings are based, accompanied by the agency’s

Case: 24-2178 Document: 41 Page: 5 Filed: 02/13/2026

GOOGLE LLC v. WILDSEED MOBILE, LLC 5

reasoning in reaching its conclusions.’” TQ Delta, LLC v.

Cisco Sys., Inc., 942 F.3d 1352, 1358 (Fed. Cir. 2019) (quot-

ing In re Lee, 277 F.3d 1338, 1342 (Fed. Cir. 2002)). “We

do not require perfect explanations . . . and ‘we will uphold

a decision of less than ideal clarity if the agency’s path may

reasonably be discerned.’” In re NuVasive, Inc., 842 F.3d

1376, 1382–83 (Fed. Cir. 2016) (quoting Bowman Transp.,

Inc. v. Ark.-Best Freight Sys., Inc., 419 U.S. 281, 286

(1974)). “We do, however, require that the Board’s own ex-

planation be sufficient ‘for us to see that the agency has

done its job.’” Alacritech, Inc. v. Intel Corp., 966 F.3d 1367,

1371 (Fed. Cir. 2020) (quoting NuVasive, 842 F.3d at 1383).

On appeal, Google argues that the Board abused its

discretion and therefore violated the APA by failing to ad-

dress Google’s arguments raised under the IM limitation of

claim 15. Appellant’s Br. 28; Reply Br. 19.

We agree with Google that the Board should have ad-

dressed claim 15’s IM limitation. The Board is required to

“articulate a satisfactory explanation . . . [that] enables the

court to exercise its duty to review the [Board’s] decisions

to assess whether those decisions are ‘arbitrary, capricious,

an abuse of discretion, or . . . unsupported by substantial

evidence.’” NuVasive, 842 F.3d at 1382 (quoting 5 U.S.C.

§ 706(2)(A), (E)). Here, the Board’s silence on the IM limi-

tation of claim 15 does not meet this requirement. Claim

15 explicitly recites generating a hot link message either

as an SMS message or an IM message. A petitioner can

therefore satisfy either of these two disjunctive limitations

to show unpatentability. Google’s petition discusses the

SMS limitation and IM limitation of claim 15. See J.A. 115,

129. Wildseed specifically addressed claim 15 for the first

time in its patent owner’s sur-reply but provided argu-

ments only for the SMS limitation. See J.A. 477. In its

final written decision, the Board analyzed claim 15 but

only regarding the SMS limitation. Although the Board

performed a thorough analysis of the SMS limitation, the

Board failed to address the IM limitation. Indeed, it made

Case: 24-2178 Document: 41 Page: 6 Filed: 02/13/2026

6 GOOGLE LLC v. WILDSEED MOBILE, LLC

no mention of IM and even omitted the IM limitation in its

quotation of claim 15. See Final Written Decision, 2024 WL

2819590, at *15.

The Board’s analysis therefore does not acknowledge

the IM limitation, much less explain that the asserted prior

art does not teach or suggest the IM limitation. Nor does

the Board provide a non-merits reason—such as failure to

include an IM-based ground in the petition, subsequent

abandonment of such a ground, waiver, or forfeiture—for

not addressing the IM limitation. Thus, we cannot reason-

ably discern the basis upon which the Board concluded that

Google has not shown that claim 15 would have been obvi-

ous over the prior art. The Board is required to “document

its reasoning on the record to allow accountability . . . [and]

effective judicial review.” In re Thrift, 298 F.3d 1357, 1364

(Fed. Cir. 2002); see Provisur Techs., Inc. v. Weber, Inc., 50

F.4th 117, 125 (Fed. Cir. 2022) (“Because the Board never

directly or implicitly addressed the arguments that [peti-

tioner] had set forth in its petition, it erred.”). We therefore

vacate and remand the Board’s decision as to claim 15.

Wildseed argues that Google stated in its petitioner’s

reply, and the Board found, that Google’s HTML argument

was limited to email only. Appellee’s Br. 11, 38. While we

cannot rule out the possibility that this was the Board’s

reason for not addressing the IM limitation, the Board’s si-

lence makes it impossible to discern and we cannot resort

to speculation. Gechter v. Davidson, 116 F.3d 1454, 1457

(Fed. Cir. 1997) (“Necessary findings must be expressed

with sufficient particularity to enable our court, without

resort to speculation, to understand the reasoning of the

Board.”). Nor can we determine if such a reading of

Google’s petition in the context of Google’s reply and other

statements Google made (and did not make) in its brief and

at the oral hearing, would constitute an abuse of discretion.

On remand, the Board needs to explain its reasoning with

respect to the IM limitation.

GOOGLE LLC v. WILDSEED MOBILE, LLC 7

Accordingly, we vacate the Board’s obviousness deter-

mination as to claim 15 and remand for further proceedings

consistent with this opinion.

CONCLUSION

We have considered Wildseed’s remaining arguments

and find them unpersuasive. For the foregoing reasons, we

vacate and remand.
