. Appellant IOENGINE, LLC (IOENGINE) appeals a series of Final Written Decisions of the United States Patent and Trademark Office’s Patent Trial and Appeal Board (Board) finding unpatentable certa in claims of U.S. Patent Nos. 8,539,047 (’047 patent), 9,059,969 (’969 patent), and 9,774,703 (’703 patent) (collectively, the Challenged Patents) during inter partes review (IPR)

B ACKGROUND The Challenged Patents share an ancestor, written description

, and title

— “Apparatus, Method and System for a Tunneling Client Access Point.” The written description discloses a tunneling client access point (TCAP) that is a “highly secure, portable, power efficient storage and data Case: 21-1227 Document: 109 Page: 2 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 3

processing device” (i.e., a “portable device” as recited in the claims). ’047 patent Abstract

. 1 T he TCAP , upon plug ging in to an access terminal (e.g., any existing desktop or laptop computer ) may make use of the terminal’s traditional userinterface and input/output peripherals, while the TCAP itself provides storage, execution, and/or processing resources. ’047 patent col. 2 ll. 39

– 46. T he TCAP thereby “tunnels” data through the ac cess terminal by allowingdata to be provided through the access terminal’s input/output facilities for the user to observe without the data actually residing on the access terminal. ’047 patent col. 4 ll. 26

– 28. The TCAP may also tunnel data through

an access terminal across a communications network to access remote servers without requiring its own more complicated set of peripherals and input/output facilities. Id. col. 4 ll. 28

– 31.

The Challenged Patents claim a “ portable device ” (the TCAP) confi gured to communicate with a terminal

. The claims recite a memory , on either the portable device or terminal, that stores first program code which, when executed, presents an interactive user interface. Also stored in memory are second , third, and fourth program code that are configured in various ways to facilitate communications , including with a communications network node.
Claim 1 of the ’969 patent i s illustrative, and recites: 1. A portable device configured to communicate with a terminal comprising a processor, an inputcomponent, an output component, a network communication interface, and a memory configured tostore executable program code, including first program code which, when executed by the terminal

. 4

processor, is configured to present an interactive user interface on the terminal output component, and second program code which, when executed by the terminal processor, is configured to provide a communications node on the terminal to facilitate communications to the portable device and to acommunications network node through the terminal network communication interface, the portable device comprising: (a) an external communication interface configuredto enable the transmission of communications between the portable device and the terminal;
(b) a processor; and (c) a memory having executable program code stored thereon, including:
(1) third program code which, when executed by the portable device processor, is configur ed toprovide a communications node on the portable device to coordinate with the communications node on the terminal and establish a communications link between the portable device and the terminal, and facilitate communications to the terminal andto a communications network node through the terminal network communication interface; and (2) fourth program code which is configured tobe executed by the portable device processor in response to a communication received by the portable device resulting from user interaction with the interactive user interface; wherein the portable device is configured to facilitate communications through the communication node on the terminaland the terminal network interface to a communications network node.

. 5

Appellee Ingenico Inc. (Ingenico) filed three petitions for IPR of the Challenged Patents. The Board issued Final Written Decisions finding certain claims of the Challenged Patents unpatentable. IOENGINE appeals

, arguing that the Board incorrectly construed the claim term “interactiveuser interface,” incorrectly applied the printed matter doctrine, and otherwise erred in its anticipation and obviousness analysis. We have jurisdiction under 28 U.S.C. § 1295(a)(4)(A).

D IS CUSSION

IIOENGINE contends that the Board erroneously construed the claim term “interactive user interface” to mean “a display containing interface elements with which a usermay interact to result in a computer taking action responsively.” In each of it s Patent Owner Responses

, IOENGINE requested that the Board construe “interactiveuser interface” to mean “a display containing interface elements with which a user may interact to result in the terminal taking action responsively by responding to the

user .” On appeal, however, IO EN GINE proposes a new claim construction that it never proffered to the Board: “a presentation containing interface elements with which a user may interact to result in the device executing code to present / affect the presentation taking action responsively by modifying what is presented.” In contrast to its position during the IPR s , IOENGINE argues on appeal that th e claims encompass either the terminal or the portable device taking responsive action

. Compare J.A. 581

– 82 ( “[T]he Petition actually agrees with Patent Owner that it is the terminal that must take action in response to the user interaction

. . . .” ), wit h Appellant’s Br. at 23 (“[I] f the terminal processor executes code to present the IUI, an ‘ interactive ’ user interface means that the terminal responds to the user; if the portable device processor executes code to present the IUI, an ‘ interactive ’ user interface means that Case: 21-1227 Document: 109 Page: 5 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 6

the portable device responds to the user. ”). Furthermore, IOENGINE’s new construction requires th e responsive action to be “modifying what is presented,” rather than “responding to the user,” as IOENGINE proposed in its Patent Owner Response during IPR. 2 IOENGINE forfeited its proposed claim construction by not presenting it to the Board during IPR

. See Monsanto Tech. LLC v. E.I. DuPont de Nemours & Co.

, 878 F.3d 1336, 1342 n.8 (Fed. Cir. 2018) ( concluding patent owner waived new claim construction argument where the construction was not proffered to the Board in inter partes reexamination proceedings)

. While we retain case

- by

- case discretion over whether to apply waiver, 3 we have held that a party waives an argume nt that it failed to present to the Board because it deprives the court of the benefit of the Board’s informed judgment. In re Nuvasive, Inc. , 842 F.3d 1376,

2 IOENGINE’s proposed construction in its PatentOwner’s Preliminary Response included “the terminal taking action responsively by modifying what is presented.” However, following the Board’s institution decision, IOENGINE ’s Patent Owner Response switched its construction to require “the terminal taking action responsively by responding to the user.” IOENGINE’s choice before the Board to drop its argument for “modifying what is presented” and pivot to “responding to the us er” seems to be a clear abandonment of “modifying what is presented.”

3 “ By and large, in reviewing this court ’ s precedent, it is evident that the court mainly uses the term ‘ waiver ’ when applying the doctrine of ‘forfeiture. ’” In re Google Tech. Holdings LLC , 980 F.3d 858, 862 (Fed. Cir. 2020)

.
“ Though previous cases may have used the term ‘waiver’ instead of ‘forfeiture,’ their holdings are good law for a case, like this one, involving the issue of forfeiture. ” Id. at 862 n.8. Case: 21-1227 Document: 109 Page: 6 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 7

1380 (Fed. Cir. 2016) (citing Harris Corp. v. Ericsson Inc.

, 417 F.3d 1241, 1251 (Fed. Cir. 2005); In re Watts , 354 F.3d 1362, 1367

– 68 (Fed. Cir. 2004) ).
IOENGINE argues that it did not forfeit its proposed construction because , in IOENGINE’s view, its constructions before the Board and this Court embody the sam e concept s

. Appellant’s Reply Br. at 9

– 10 (citing Gaus v. Conair Corp. , 363 F.3d 1284, 1288 (Fed. Cir. 2004)). We disagree. Requiring a terminal to take responsive action differs meaningfully from requiring either the terminal or the portable device to take responsive action. Requiring the responsive action to respond to the user also differsmeaningfully from requiring the responsive action to modify what is presented. We accordingly find that IOENGINE forfeited its proposed claim construction.

II

We next address IOENGINE’s challenge s to the Board’s anticipation determinations. “[A] nticipation is a question of fact subject to substantial evidence review.” Microsoft Corp. v. Biscotti, Inc. , 878 F.3d 1052, 1068 (Fed. Cir. 2017). “Substantial evidence is ‘ such relevant evidence as a reasonable mind might accept as adequate to support a conclusion. ’” In re Applied Materials, Inc. , 692 F.3d 1289, 1294 (Fed. Cir. 2012) (quoting Consol . Edison Co. v. NLRB

, 305 U.S. 197, 229 (1938))

. IOENGINE contends that the Board erred in concluding that U.S. Patent Application Pub. No. 2003/0020813A1 ( Iida ) anticipates certain challenged claims of the ’969 and ’703 patents. According to IOENGINE, Iida fails to disclose a n interactive user interfac e even under the Board’s construction , on the grounds that the “menus” of Iida are static images that provide no interactivity because they lack “clickable elements, checkboxes, or pointer events, ”

“ positional feedback, ” or any “ other way to engage .” Appe llant’s Br. 30. IOENGINE also argues tha t Iida’s disclosure Case: 21-1227 Document: 109 Page: 7 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 8

of pressing a number on a separate keypad involves no interaction with interface elements. The Board considered these arguments and found them unpersuasive. Relying on testimony by the petitione r’s expert Mr

. James Geier, t he Board reasonably found that Iida’s menu screens , which display choices that a user can select, disclose interactive interface elements, and that Iida also discloses taking action in response to user selections

. J.A. 144

– 45. As to IOENGINE’s argument that Iida’s interaction with a separate keypad does not disclose interaction with interface elements, the Board “decline[d] to import a limitation requiring that user interaction bebased on location and/or movement of a user’s point of interaction .” J.A

. 145. We see no reason to disturb the se findings by the Board

. IOENGINE also argues that Iida fails to disclose “second program code ” providing a “ communications node” on the terminal and “thir d program code” providing a “communications node” on the portable device , as required by certain claims of the Challenged Patents

. According to IOENGINE, the Board erred by relying on Mr

. Geier’s testimony to infer a missing claim element not disclosed in Iida

. But the Board ’s finding s relied on Mr. Geier’s testimony that (1) Iida’s control unit (the disclosed terminal) acts as a communication s node by execut ing code to perform configurations to enable the terminal to communicate

over a n etwork , and (2) Iida’s camera (the disclosed portable device) establishes its own communications node to coordinate network communications

. J.A. 138

– 39, 140

– 41 ; J.A. 233

– 34 , 238

– 39

. The Board also relied on disclosures in the Challenged Patents’ own writ ten description that the terminal or portable device may itself act as a communications nod e. S ubstantial evidence thus support ed the Board’s finding that Iida discloses program code providing

a “ communication s node .” We therefore affirm the Board’s anticipation determinations as to all claims aside from Case: 21-1227 Document: 109 Page: 8 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

claims 4 and 7 of the ’969 patent and claims 61

– 62 and 110

– 11 of the ’703 patent, which we discuss next

. I II
We turn, then, to IOENGINE ’s argu ment that the Board erred in applying the printed matter doctrine to determine that Iida anticipates claims 4 and 7 of the ’969 patent and claims 61

– 62 and 110

– 11 of the ’703 patent. In particular, IOENGINE argues that the Board incorrectly applied the printed matter doctrine to accord no patentable weight to certain claim limitations t hat recite “encrypted communications” and “program code .”

“ This court and its predecessor have long recognized that certain ‘ printed matter ’ falls outside the scope of patentable subject matter under U.S. patent law. ” C R Bard Inc. v. AngioDynamics, Inc. , 979 F.3d 1372, 1381 (Fed. Cir. 2020) (citing AstraZeneca LP v. Apotex, Inc. , 633 F.3d 1042, 1064 (Fed. Cir. 2010) ; In re Chatfield , 545 F.2 d 152, 157 (CCPA 1976) ) . Although “printed matter” historically referred to claim elements involving actual “printed” material, today the doctrine has expanded to include any information claimed for its communicative content , regardless of medium

. Id.
We apply a two

- step test to determine whether a limitation should be accorded patentable weight under the printed matter doctrine. First, we determine whether the limitation in question is directed toward printed matter. In re Distefano , 808 F.3d 845, 848 (Fed. Cir. 2015). A “limitation is printed matter only if it claims the content of information.” Id. Put another way, printed matter is “matter claimed for what it communicates.” Id. at 850. “Only if the limitation in question is determined to be pr inted matter” do we proceed to the second step, which asks “whether the printed matter nevertheless should be given patentable Case: 21-1227 Document: 109 Page: 9 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 10

weight.” 4 Id. “Printed matter is given such weight if the claimed informational content has a functional or structural relation to the substrate. ” Id.
Claims 4 and 7 of the ’969 patent, to which the Board applied the printed matter doctrine, both depend on claim 2, which requires the “fourth program code [] when executed by the portable device processor, [ to be ] configured tocause a communication to be transmitted to the communication network node.” Claim 4 of the ’969 patent recites

“ wherein the communication caused to be transmitted tothe communication network node facilitates the transmission of encrypted communications from the communication network node to the terminal .” In other words, claim 4 contemplates the portable device sending a communication to the communication network node, which in turn facilitates sending encrypted communications to the term inal. T he Board determined that the term “‘encrypted communications’ claims only communicative content, i.e. printed matter” because it found “ nothing in the claim that requires anything beyond sending and receiving data, even if the data is in an encrypted form .” J.A

. 151. The Board further found that there was “no functional relationship of the encrypted data to the communication carrying it” because nothing in the claims required “the data being used or manipulated” or “any processing of encrypted dat a beyond the transmission of the same .” Id. The Board thus concluded that the limitation should be afforded no patentable weight.
We disagree with the Board that the claimed “encrypted communications” constitute printed matter. As discussed above, p rinted matter is matter that is claimed for its communicative content

— i.e., the content specifically

4 Giving a limit ation “patentable weight” means it may be used as a basis for distinguishing prior art. Distefano , 808 F.3d at 848. Case: 21-1227 Document: 109 Page: 10 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 11

being communicated

. The fact that there is a communication itself is not content; content is what the communication actually says. Nor is the form of a c ommunication,such as whether the communication is encrypted, considered to be content. Printed matter encompasses what is communicated

— the content or information being communicated

— rather than the act of a communication itself.
We have previously found that an FDA label providing dosage instructions for using a medical product is printed matter, that a label instructing a patient to take a drugwith food is printed matter, that instructions on how to perform a DNA test are printed matter, and that numbe rs printed on a wristband are printed matter. Distefano , 808 F.3d at 849

– 50 (collecting cases). Unlike those examples

, which claim communicative content such as medical instructions or numbers, the encrypted communications here are not being claimed for any content that they are communicating. We therefore find that the claimed “encrypted communications” do not constitute printed matter.
The Board also declined to afford patentable weight to the “program code” limitation recited in claim 7 of the ’969

pa tent and claims 61

– 62 and 110

– 11 of the ’703 patent. The relevant limitation in claim 7 of the ’969 patent recites

“ the communication caused to be transmitted to the communication network node facilitates the download of program code on the communication network node to the terminal.” That is, in claim 7, the communication to the communication network node facilitates the download of program code to the terminal , rather than the transmission of encrypted communications , as described above in claim 4

. Similarly, claims 61

– 62 and 110

– 11 of the ’703 patent recite “ caus [ing] a communication to be transmitted to the communications network node to facilitate the download of program code from the communications network node to the” terminal or portable device. As to claim 7 of the ’969 patent , the Board determined that “‘program code’ in claim 7 is not entitled to patentable weight” because the “recital Case: 21-1227 Document: 109 Page: 11 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 12

of ‘downloading’ of program code in claim 7 is limited to downloading (sending or transm itting) the code, which is a communication, and no other function is recited in the claim.” J.A. 155. As to claims 61

– 62 and 110

– 11 of the ’703 patent, the Board determined that “program code” “is ‘printed matter’ because it claims the content of the information that is downloaded,” J. A. 253, and that it is not entitled to paten table weight because “the downloaded code is merely generic and has no functional relationship with either the portable device or the terminal,” J.A

. 255. Here, too, we disagree with the Board. The “p rogram code” is not claimed for its communicative content ; no informational content is claimed

. See Distefano

, 808 F.3d at 851 ( “A lthough the selected web assets can and likely do communicate some information, the content of the information is not claimed .” ). Indeed, the claim is altogether silent as to the contents of the claimed “program code.” That the code is being downloaded does not change the analysis

. Because the re is no particular content being claimed, the program cod e is not printed matter. To conclude otherwise would impermissibly expand the printed matter doctrine far beyond its current scope

. Because “encrypted communications” and “program code” are not being claimed here for the content they communicate, they are not printed matter. The inquiry stops there; if the claim element is not printed matter, we need not consider whether it has a functional or structural relation to its substrate

.Finally, no remand is needed because Ingenico conceded at oral argument that it did not submit alternative grounds for invalidity, other than the printed matter doctrine, with respect to the “encrypted communications” and “program code” limitations. Oral Arg

We next address IOENGINE’s challenge s to the Board’s obviousness determinations. Th is court reviews the Board’s ultimate obviousness determination s de novoand its underlying factual findings for substantial evidence. Novartis AG v. Torrent Pharms. Ltd. , 853 F.3d 1316, 1327 (Fed. Cir. 2017) . “ Motivation to combine is one of those underlying factual issues. ” Id. (citing In re Gartside , 203 F.3d 1305, 1316 (Fed. Cir. 2000) ). “ What a reference teaches and the differences between the claimed invention and the prior art ” are also questions of fact

. In re Cuozzo Speed Technologies, LLC , 793 F.3d 1268, 1280 (Fed. C i r. 2015)

. According to IOENGINE, a skilled artisan would nothave been motivated to combine Iida with U.S. Patent Applicatio n Pub. No. 2002/0065872 (Genske) because “Genske’s computer

- based GUI contradicts Iida’s core reliance on the camera to provide static images to ensure compatibility with even the lowest -common-denominator phone.” Appellant’s Br. 44. IOENGINE also argues that the combination was based on hindsight, give n certain gaps in Iida and Genske ’s disclosures

. Id. at 45

. IOENGINE further argues that the Board improperly mixed and matched embodiments disclosed in those references to arrive at the claimed invention. Id. at 47.

We find each of these argument s to be unpersuasive. T he Board relied on the petitioner’s expert testimony , as well as the disclosures in Iida and Genske themselves, to conclude that a skilled artisan would h ave been motivated
to com bine Iida and Genske. J.A

. 41 –48

. S ubstantial evidence supported the Board’s finding

. The Board also addressed IOENGINE’s argument as to the purported gaps in Iida and Genske’s disclosures by noting that “ ‘ [t]he question in an obviousness inquiry is whether it would have Case: 21-1227 Document: 109 Page: 13 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 14

been obvious to a person of ordinary skill in the art to combine the relevant disclosures of the two references, notwhether each individual reference discloses all of the necessary elements. ’ ” J.A

. 40 (quoting Game & Tech . Co., Ltd. v. Wargaming Grp. Ltd. , 942 F.3d 1343, 1352 (Fed. Cir. 2019) ). We find that the Board appropriately combined relevant disclosures of the two references in its obviousness analysis, and that there was no impermissible “ mixing and matching, ” as IOENGIN E contends.

IOENGINE further argues that the Board erred in d etermining that Iida discloses certain claim limitations in the ’047 patent. First, IOENGINE contends that the Board erred in finding that Iida teaches the “second program code ” which, when exec uted, “ enables the portable device
to

. . . cause a communication to be sent

, ” as recited in claims 1, 24, and 27 of the ’047 patent. Appellant ’ s Br. 54 (emphasis omitted). IOENGINE argues that claims 1 and 24 expressly require the second program code to be stored in the memory of the portable devic e, but that Iida discloses the code being stored on the terminal. Appellant’s Br. 54

– 55. The Board disagreed, finding that the petitioner sufficiently showed that “ program code stored on Iida’s

camera (portable device) performs the functions required in claim 1 for ‘second program code

. ’” J.A. 50

– 51 (citing Iida , J.A. 1229 , at ¶¶ 54, 65; FIG. 4C)

. Moreover, the Board noted that “[n]othing in the claim language requires that all communication

- related p rogram code reside [] on the portable device, as opposed to the terminal .” J. A. 51. We find the Board’s analysis reasonable, and thus supported by substantial evidence.
Second, IOENGINE contends that the Board erred in finding that Iida discloses the limi tation reciting that “executing the first program code

. . . causes the terminal processor to present an interactive user interface on the first output component ” in claim 25 of the ’047 patent

. The Board considered and reasonably rejected this argument, noting that IOENGINE’s position is “premised on an Case: 21-1227 Document: 109 Page: 14 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC

. 15

implicit claim construction ” that “present an interactiveuser interface” refers to controlling and generating the content of the interface. J. A. 68. The Board relied on “the ’047 patent’s other uses of the word ‘present’” to conclude that

“‘ present’ simply refers to showing or displaying ,” with no requirement that the presentation be generated by a certain device. J. A. 69. From this, as well as Iida’s disclosures, the Board concluded that Iida discl oses the disputed limitation of claim 25. We see no error in the Board’s understanding of the claim term “present,” and thus find that substantial evidence supported the Board’s conclusion

. Finally, IOENGINE argues that the Board erred in its determinati on that claims 74, 89, 100, and 123 of the ’703 patent , which include the limitation “ wherein the data stored on the portable device memory comprises a digital certificate,” are rendered obvious by Iida in combination with U.S. Patent No. 6,088,805 (Davis)

. IOENGINE alleges that it would not have been obvious to substituteIida’s username and password for Davis’s certificates because the certificate in Davis is associated with a client device, not a user. Appellant’s Br. 63. But the disclosure in Davis t hat the Board relied on expressly discusses individual user HTTP

- layer authentication that may be accomplished via digital certificates. J.A

. 274 (citing J.A. 14837 col. 1 ll. 38

– 45 ). We find no error in the Board’s determination that it would have been obvious to a skilled artisan to combine Iida and Davis to arrive at the claimed “digital certificate.”
Based on the foregoing, we affirm the Board’s determinations as to all claims found to be obvious

. C ONCLUSION
We find none of IOENGINE’s remaining a rguments persuasive. For the foregoing reasons, we reverse the Board’s determinations of unpatentability as to claims 4 and 7 of the ’969 patent and claims 61

– 62 and 110

– 11 of Case: 21-1227 Document: 109 Page: 15 Filed: 05/03/2024IOENGINE , LLC v. INGENICO INC
