“We maintain the definition of a person having ordinary skill in the art that we adopted in the Institution Decision. First, it is supported by the testimony of Dr. Akl. Ex. 1003 ¶ 22. Second, Patent Owner states that it adopts that definition. PO Resp. 3. Third, to the extent Patent Owner proposes expanding the definition, Patent Owner has not explained how that difference would materially affect the outcome of this proceeding. Id. Fourth, Patent Owner does not point to sufficient evidence to support its position. Id.

“In determining the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed.

Neither party argues, at least at this stage of the proceeding, that the outcome of this case would differ based on our adoption of any particular definition of the level of ordinary skill in the art. Considering the subject matter of the ’868 patent, the background technical field, the prior art, and Petitioner’s proposed and unopposed definition of the skilled artisan (Ex. 1012 ¶ 20), we apply the level of skill set forth above.” slip op. at 8

“Only those claim terms that are in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

Resp. 4). In determining at this stage of the proceeding that Petitioner has demonstrated a reasonable likelihood of establishing unpatentability of at least one challenged claim (namely dependent claim 11 in this case), we need not and do not construe expressly any claim terms. Nevertheless, we encourage the parties to submit proposed constructions for the limitation “determining a UE [i.e., User Equipment] environment information,” as recited in dependent claim 11. See Ex. 1001, 49:12–15, 1:40–42 (emphasis added). To the extent that a party proposes that this limitation should have its ordinary and customary meaning, the party should submit and explicitly identify such meaning. O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”). For example, the parties should discuss (a) the meaning and scope of “determining” as used in the subject limitation; (b) the meaning and scope of “environment information” as used in the subject limitation; (c) any relationship or overlap between “environment information” and “link quality positioning information,” as recited in dependent claims 7 and 11 (see Ex. 1001, 48:62–65, 49:12–15); and (d) whether UE “environment information” includes location or orientation of the UE.” slip op. at 10

“Petitioner contends the skilled artisan would have had rational reasons to combine the teachings of Jarvinen and Fox to arrive at the invention of dependent claim 11 (which includes the features of independent claim 1 and dependent claim 7) and would have had a reasonable expectation of success in doing so. Pet. 37–41; see, e.g., id. at 38 (“[The skilled artisan] faced with the problem of estimating a UE’s future link quality at a location would have looked to Fox because Fox solves the problem of estimating future link quality with the exact same information available to Jarvinen.”); Ex. 1012 ¶ 70 (Dr. McClellan testifying that “[a]ll of the data upon which Fox relies is already disclosed and linked together in Jarvinen’s database, and it would have been obvious for [the skilled artisan] to combine Fox’s method of looking up previous link quality to estimate future link quality with Jarvinen’s teachings.”); ¶ 72 (Dr. McClellan testifying that “modifying Jarvinen to perform Fox’s link quality estimation would have constituted a simple substitution of a known element to yield predictable results.”). Patent Owner does not dispute such reasons or expectations at this stage of the proceeding. For the reasons and evidence set forth in pages 37–41 of the Petition, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox to arrive at the invention of claim 11, and to do so with a reasonable expectation of success. c) Summary At this stage of the proceeding and based on the record before us, we are persuaded that Petitioner’s cited evidence provides sufficient rational reasons for purposes of institution to combine Jarvinen and Fox with a reasonable expectation of success, and sufficiently supports Petitioner’s contention that dependent claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox. Thus, for the foregoing reasons and those stated in Petitioner’s preliminary briefing (Pet. 17–47, 50–51, 54), we determine that Petitioner has established a reasonable likelihood that it would prevail in showing that claim 11 would have been unpatentable as obvious over the combination of Jarvinen and Fox.” slip op. at 18

“construction principles, and does not revise or ignore the explicit language of the claims.”). In that vein, “[p]roper claim construction . . . demands interpretation of the entire claim in context, not a single element in isolation.” Hockerson–Halberstadt, Inc. v. Converse Inc., 183 F.3d 1369, 1374 (Fed.Cir.1999); accord Phillips, 415 F.3d at 1314 (“[T]he context in which a term is used in the asserted claim can be highly instructive.”). Patent Owner’s interpretation that “the current version” requires two current versions — one locally stored current version and a corresponding remotely stored current version — asks us to improperly adopt a claim construction which ignores explicit claim language and context in order to read unrecited features into the claim. The limitation in question, more fully and in better context, recites “storing the selected previous version . . . as the current version on the local storage location.” Ex. 1001, 9:24–26 (emphasis added). The express language shows that the claim is specifically directed to the current version on the local storage location and not any possible remote current version. As such, even if there were a “current version on the remote storage location” which corresponds to and is kept in parity with the current version on the local storage location, i.e., a backup copy of the locally stored current version, the claim does not recite that feature, establishing that it does not require that feature. Further, as to the context of the claim, the term in question is part of a recited method of restoring a file to a previous version of the file on a local computational machine, rather than a method for maintaining parity of remotely stored backup files during that restoration process. See id. at 8:63–9:28. As such, the explicitly recited claim language and the context of the claim do not support reading an unrecited remote backup feature into the claim.” slip op. at 11

First, regarding the technical operation of Sweat’s download function, Petitioner explains that a user “download[s] a version of [a] file from the server 106 to the local computer 104” and selects a local “target location to save the selected file.” Id. at 61 (citing Ex. 1006, 10:58–63).

“We agree with Petitioner. Sweat’s description of its “Viewing Files” feature explains that “a user must install the appropriate viewer to open and view drawing files.” Ex. 1006, 23:38–41. Sweat lists examples of such viewers including software applications such as Volo™ View Express. Id. at 23:45–46, 23:63–67. While Sweat does not list a CAD file creating application in its exemplary list of viewers in that “Viewing Files” section (see id. at 23:38–24:35), elsewhere, Sweat states that a CAD application, e.g., “AutoCAD®,” is “drawing/viewing software utilized by the viewer” (id. at 23:29–33). Furthermore, Petitioner’s declarant offers undisputed testimony that AutoCAD is software for creating CAD drawing files and can also be used to view those created CAD drawing files. Ex. 1024 ¶ 39 (citing Ex. 1029, 19–23, 541–542). On that evidence, we agree a POSITA would understand that Sweat describes using a viewer to preview previous versions of CAD drawing files and that Sweat also describes AutoCAD (which creates CAD drawing files) can be used as a viewer. In light of that understanding, we agree it would have been obvious to use AutoCAD, i.e., “an application that created the file,” to preview previous versions of that file. Pet. 62–63. We also agree that it would have been rational to do so because the same already locally available software application which created the file could then be used to view the file. Id.; see Ex. 1004 ¶ 128. Owner dismisses Petitioner’s obviousness argument as “irrelevant,” and, instead, argues that Sweat does not disclose the claimed features. PO Sur- Reply 16–17; see PO Resp. 39–40. In particular, Patent Owner argues Sweat “discloses the use of specialized viewing software to view the related file” and emphasizes that “CAD software is clearly not being used in Sweat’s ‘View in Window’ functionality” PO Resp. 39–40 (citing Ex. 1006, 23:39–51); PO Sur-Reply 17. While it may be the case that Sweat does not outright disclose the features recited in the claim, those arguments do not show fault in Petitioner’s case that the claimed features would have been obvious.

RulingsFinal written decision- Skill levelSkill level patent owner adoptedDecided for patent owner
“Patent Owner argues for a slightly different level of ordinary skill in the art: “a bachelor’s degree in electrical engineering, computer engineering, computer science, or a similar field, along with one to two years of experience developing or programming video games or video game systems, or similar types of computer systems.” PO Resp. 2 (citing Ex. 2006 ¶ 29). Patent Owner further argues that the person having ordinary skill in the art “may have additional education that might substitute for some of the experience, and additional experience might substitute for some of the educational background.” Id. (citing Ex. 2006 ¶ 29). According to Patent Owner, Petitioner’s proposal does not require experience in programming video games. Id. at 3. However, Patent Owner states, “[t]his difference does not materially affect the analysis presented below.” Id. We see very little difference between the parties’ respective proposals. We adopt Patent Owner’s marginally more specific proposal. Additionally, because we would reach the same conclusions under Petitioner’s proposal, we agree with Patent Owner that this does not affect our analysis.” slip op. at 9

“Patent Owner argues that the plain and ordinary meaning of “downloading” excludes “real-time fetching of data by a client from a server system.” PO Resp. 34; see also PO Sur-reply 16–17; Tr. 32:22–34:7. Because we need not expressly construe any claim terms, we do not construe any terms of the ’662 patent. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co. Matal, 868 F.3d 1013, 1017 (Fed. Cir. 2017) (noting that “we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy’” (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999))).” slip op. at 11
- Novelty / Anticipation (§102) › Prior-art status of a reference › Printed publication / public accessibilityPrinted publication establishedReference is prior artDecided for petitioner
“date of the ’662 patent, Ho is not a “printed publication” within the meaning of 35 U.S.C. § 311(b). PO Resp. 30–33; PO Sur-reply 15–16. The Federal Circuit has rejected this argument, holding that: a published patent application is, by its literal terms, a “printed publication.” So, when § 311(b) permits IPR challenges based upon “prior art . . . printed publications,” it includes within its literal scope challenges based upon a published patent application. And, by virtue of § 102(e)(1), a published patent application—this specific type of “printed publication”—is deemed prior art as of its filing date. Therefore, the plain language of §§ 311(b) and 102(e)(1) permits IPR challenges based upon published patent applications, and such published patent applications can be deemed prior art in IPRs as of their filing date. Lynk Labs, Inc. v. Samsung Elecs. Co., 125 F.4th 1120, 1127 (Fed. Cir. 2025). Thus, Petitioner asserts permissible grounds of unpatentability under 35 U.S.C. § 311(b) by arguing that claims 1–20 are unpatentable under 35 U.S.C. § 103(a) on the basis of Ho, which is a prior art printed publication, and either Aoki or Kim.” slip op. at 11
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner
“A person having ordinary skill in the art would have combined Aoki’s teaching of using user-identification information as part of the request for an advertisement with Ho’s system, which also teaches a client device sending information to a server to request hot spot information, such as advertisements. See Ex. 1003 ¶¶ 103–107, 111, 114, 117. Because both Ho and Aoki are directed to improvements in game design and monetization from using advertisements (id. ¶ 106; Ex. 1004, 1:26–28; Ex. 1005 ¶¶ 6–8), a person having ordinary skill in the art would have looked at both Ho and Aoki and combined the relevant features with a reasonable expectation of success (Ex. 1003 ¶¶ 103, 106, 117). A person having ordinary skill in the art would have appreciated that using Aoki’s teaching of sending user-identification information with Ho, which includes sending information with a request for information relating to interactive information elements (hot spots), allows for targeted advertisements, which was a known advantage in advertising. Id. ¶ 117; Ex. 10089 ¶¶ 54–55 (describing advantages of targeted advertising).” slip op. at 26
