“proposed constructions, and determined that “event node” does not need construction. Ex. 2007, 5. In the Institution Decision, we agreed with the District Court that “event node” does not need construction, and we continue to do so here. See Inst. Dec. 8. Independent claim 1 recites “creating, by an event node server, an event node in a multi-dimensional personal information network, the event node corresponding to a situation,” “transmitting an invitation to establish a link with the event node server to the devices corresponding to each node in the projection formed in step (b),” “receiving a response from at least one of the devices from step (c) accepting the invitation to establish a link with the event node server,” and “establishing a link with each device accepting the invitation.” Ex. 1001, 33:21–35; see also PO Resp. 3 (emphasizing claim 1’s recitations that the “event node” is “in a multi-dimensional personal information network” and “correspond[s] to a situation.”). Claim 20 includes similar recitations related to the “event node.” Ex. 1001, 34:45–64. In view of this, we determine that the claim language itself provides sufficient meaning for the term “event node” and further construction is not necessary.9” slip op. at 10

“event node.” Petitioner persuades us that Amidon’s architecture provides a social network (the recited “situational network”) and the social network conference within the social network is the event node. In particular, the evidence demonstrates that Amidon separately teaches a social network and a social network conference. For example, as Petitioner notes, Amidon suggests that a conference may include a subset of the users in its social network, such as “all users currently listening to the same song” or “a subset of a social network circuit related to a game when the subset includes three or more people.” Ex. 1005, 13:6514:3, 14:22–27; Pet. 20–22; see also Ex. 1005, 13:57–14:29. Therefore, Patent Owner’s argument that the social network conference is the social network (see Sur-reply 6–8), rather than the event node, does not persuasively address Petitioner’s contentions.10 Patent Owner’s argument that Amidon’s social network conference merely comprises a group of individuals communicating with each other so it cannot be an event node does not take into account that Amidon’s social network conference is also defined by a data structure, such as the data structure shown in Figure 3. See PO Resp. 7–10; Pet. 19–20; Reply 7–8. The parties do not dispute that Amidon’s social network conference is defined by a data structure. PO Resp. 11–13 (e.g., “Fig. 3 shows a database entry for a conference.”); Reply 7. We find persuasive Petitioner’s argument that “the conference itself (as defined by the stored data and accessible via window 200) is the claimed event node.” Reply 7. slip op. at 20

“Weighing the Parties’ arguments and evidence, Petitioner persuades us that a person of ordinary skill in the art would have had motivation to configure Wong’s social network with an ad-hoc communication network like Gogic’s, as well as a reasonable expectation of success. As Petitioner argues, Gogic’s disclosure that the ad-hoc communication network “may allow emergency services to be more efficiently or more appropriately deployed” would have motivated adding such an ad-hoc communication network to Wong’s system. Pet. 48; Ex. 1007, 4:20–24. Additionally, contrary to Patent Owner’s arguments, Petitioner’s evidence demonstrates technical compatibility of the references’ disclosures. As Petitioner notes, Gogic discloses using its approach with a wide range of technologies, including “portable or desktop computers.” Ex. 1007, 4:46– 49; Pet. 48. Wong likewise discloses implementing its social network with a wide range of technologies, such as “laptops, desktops, handheld, personal digital assistants, personal digital assistants, [or] mobile telephones.” Ex. 1006 ¶ 17; Pet. 49. These disclosures show that a person of ordinary skill in the art would have had a reasonable expectation of success implementing Gogic’s method in Wong’s social network using, for example, desktop computers.11 Patent Owner recognizes that Gogic discloses implementing its system with desktop computers. PO Resp. 22. But Patent Owner contends that a person of ordinary skill in the art would not have known how to implement Gogic’s invention, such as its location determination, using desktop computers. Id. This argument does not recognize that, as a prior art patent, Gogic is presumed enabled, including its disclosure of using desktop computers to implement its system. Apple Inc. v. Corephotonics, Ltd., 861 F. App’x 443, 450 (Fed. Cir. 2021) (nonprecedential; inter partes review context); Amgen Inc. v. Hoechst Marion Roussel, Inc., 314 F.3d 1313, 1354 (Fed. Cir. 2003). Patent Owner’s arguments and evidence do not rebut this presumption. For example, Dr. Rubin’s testimony that “from the descriptions and figures provided in Gogic it would suggest that location is determined via technologies specific to wireless networks and telecommunications” does not persuade us that Gogic fails to enable 11 Accordingly, Patent Owner’s argument about the difficulties of modifying Gogic to use Wong’s social network are inapposite. PO Resp. 24. implementing its approach with desktop computers, such as those used in Wong. Ex. 2009 ¶ 87 (emphasis added). To the extent Gogic suggested wireless technologies as a way to determine location, that does not detract from Gogic’s disclosure of using other technologies, including desktop computers, to implement its invention.” slip op. at 35

“In summary, the extrinsic record shows that, in the context of wireless network communications using the IEEE 802.16 standard, a “mobile device” is distinct from and excludes a device that is “fixed” or “portable,” where a “mobile” device is described as a device that is mobile during wireless network communications, and a “fixed” or “portable” device is described as a device that is fixed or slowly moving during wireless network communications. See Ex. 1005 ¶ 11; Ex. 1025, 24, 34, 38, 45; Ex. 2025, 71. This understanding of a “mobile device” from the extrinsic record is consistent with the language of claim 7 which recites a mobile device configured for wireless network communications (e.g., receiving an identifier and a signal from a base station), and consistent with the ’450 Patent disclosure that repeatedly and consistently utilizes the term “mobile device.” Accordingly, based on the record, we construe “mobile device” as a device that is mobile during wireless network communications, and is not fixed or slowly moving during wireless network communications.” slip op. at 19

“We do not agree with Petitioner’s arguments because, as explained above in Section III.B., we construe “mobile device” as a device that is mobile during wireless network communications, and is not fixed or slowly moving during wireless network communications. Thus, after having considered both parties’ arguments and the cited supporting evidence, we are not persuaded that the combination of Park and IEEE 802.16-2004, including the application of Park to WiBro’s teaching of stationary or slowly moving devices communicating using band AMC, teaches or suggests a “mobile device,” as properly construed, that is configured to perform the limitations recited in the body of claim 7.” slip op. at 36
