“Petitioner argues that at the time of the application for the ’986 patent (January 2002), a person of ordinary skill in the art would have had “a bachelor’s degree in electrical engineering or a related field, plus at least two years of industry experience or graduate-level academic experience with computer networking.” Pet. 20. In the Decision on Institution, the Board agreed with and applied Petitioner’s proposed definition, removing the phrase “at least” to avoid unnecessary ambiguity. Dec. on Inst. 18–19. Patent Owner uses Petitioner’s proposed definition for its Response. PO Resp. 5. Neither party made any further argument regarding the level of ordinary skill in the art in its papers during trial. In the Cisco IPR, we adopted a similar definition, determining that a person of ordinary skill in the art would have had “a bachelor’s degree in computer science, computer engineering, electrical engineering, or in an equivalent field, or approximately two years of experience working in the field of information technology and networking,” where “[l]ack of professional experience can be substituted by additional education, and vice versa.” IPR2024-00505, Paper 29 at 10–11 (alteration in original); see Dec. on Inst. 19 n.7 (noting the proposed definition in the Cisco IPR). Based on the full record developed during trial, including our review of the ’986 patent and the types of problems and solutions described in the ’986 patent and cited prior art, we adopt the same definition of the level of ordinary skill in the art as the Cisco IPR and apply it for purposes of this Petitioner’s similar proposed definition in this proceeding.” slip op. at 12

“Gai discloses entering an Enable_Uplinkfast command at an access switch (e.g., access switch 114) to block a failed port (e.g., the root port) and configure the access switch to send dummy traffic upstream through a new active port. . . . When modified in view of IEEE 1999’s disclosure that self-healing network traffic can advantageously be sent both upstream and downstream, the command would be entered at a backbone switch (e.g., backbone switch 122) to block a failed port (e.g., a designated port connected to access switch 114) and configure the backbone switch to send dummy traffic downstream to an access switch (e.g. access switch 114) through a new active port. While Gai uses its protocol signaling command, Enable_Uplinkfast, to send dummy traffic through a new root port, [a person of ordinary skill in the art] would deem it an obvious implementation detail to modify the parameters of the port on a backbone switch.

“In the Cisco IPR, we addressed four claim terms in the final written decision: “access switch” and “edge switch,” which appear in independent claims 1 and 13 and various dependent claims, and “downstream” and “upstream,” which appear in claims 11, 12, 23, and 24. IPR2024-00505, Paper 29 at 11–14. We interpreted “access switch” to mean “a switch with ports that connect to LANs and/or to other network endpoints, such as user computer systems,” interpreted “edge switch” to mean “a core switch that is directly connected to an access switch,” interpreted “downstream” to mean “away from the root switch,” and interpreted “upstream” to mean “toward the root switch.” Id. As noted above, Patent Owner did not appeal that decision. We incorporate herein our previous analysis in the Cisco IPR, but note that none of the analysis of the disputed issues below depends on such determine whether Petitioner has met its burden to prove unpatentability of the challenged claims. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

“1999, supported by the testimony of Mr. McNair, which we credit, is persuasive. See Pet. 25–30, 40–46; Ex. 1003 ¶¶ 132–145, 165–174. Based on the full trial record, we find that Gai and IEEE 1999 teach limitation [1E] and that a person of ordinary skill in the art would have been motivated to combine their teachings in the manner described by Petitioner. Based on all of the evidence of record, we determine that Petitioner has proven, by a preponderance of the evidence, that claim 3 would have been obvious over Gai and IEEE 1999 under 35 U.S.C. § 103(a). 4. Claims 8, 15, and 20 Claim 8 depends indirectly from independent claim 1. Claims 15 and 20 depend indirectly from independent claim 13, which is similar to claim 1 but recites a network switching device rather than a method. As to independent claim 13, Patent Owner refers to its earlier arguments regarding claim 1, asserting that limitation [13C] is “substantially similar” to limitation [1E]. PO Resp. 14–15. We disagree with Patent Owner’s arguments for the reasons explained above. See supra Section II.D.3.b. Patent Owner does not argue dependent claims 8, 15, and 20 separately from their respective parent claims 1 and 13. See PO Resp. 19. We have reviewed Petitioner’s contentions and supporting evidence, including the testimony of Mr. McNair, and are persuaded that Petitioner has proven, by a preponderance of the evidence, that claims 8, 15, and 20 would have been obvious based on Gai and IEEE 1999 under 35 U.S.C. § 103(a), for the reasons stated by Petitioner.

“Ex. 1001, 4:46–50. This passage indicates that the interconnect can be a network on a chip and the network on a chip can include wires and buses. That does not necessarily mean that the interconnect can be just wires or buses; rather, it discloses that the interconnect can include wires and buses. In context, the disclosure regarding wires and buses does not support construing the corresponding structure broadly enough to encompass just wires and buses. The networks that constitute the corresponding structure, however, could include networks with wires and buses. Therefore, we agree with Patent Owner that the corresponding structure for the interconnect means should not include a mere bus, switch, and point-to-point wire and instead find that the corresponding structure under 35 U.S.C. § 112 ¶ 6 is a network, which the ’052 patent describes as a multi-hop interconnection between modules separated by one or more network nodes. See Ex. 1001, 2:33–37. Because this structure corresponds to the construction of “interconnect means” proposed by Patent Owner and adopted by the district courts in the TI and Qualcomm litigations (see supra Section III.C.3.b), and we do not rely in our analysis below on a recourse to “equivalents thereto” as permitted by § 112 ¶ 6, we note that our ultimate conclusions on the unpatentability of the challenged claims would be the same if § 112 ¶ 6 did not apply. iii. Conclusion For the reasons stated above, we construe “interconnect means” to cover the structure described in the Specification corresponding to the specified functions of “coupling said plurality of processing modules (M, S)” in the context of claim 6 and “coupling said plurality of processing modules (M, S)” and “enabling a connection-based communication having a set of connection properties” in the context of claims 1 and 7—i.e., a “multi-hop interconnection between modules separated by one or more network nodes”—and equivalents thereof.” slip op. at 28

Although there is corroborating evidence of diligence beginning on November 6, 2008, when Mr. Taniguchi transmitted a draft application to the Baba law firm, there is no evidence of any diligence prior to that date, other than Mr. Taniguchi’s own testimony.

Although Mr. Taniguchi doubtlessly spent substantial time preparing the application he completed on November 6, 2008 (see Ex. 2017), there is no corroborating evidence that this work was reasonably continuous during the critical period. As far as the corroborating evidence attests, Mr. Taniguchi could have done no work on the draft until early November, or he could have worked on the draft briefly in August and put it aside until early November. Considering all the evidence as to Mr. Taniguchi’s activities, we find that Patent Owner has not met its burden of producing corroborating evidence that the named inventors of the ’427 patent exercised reasonably continuous diligence during the critical period when Ueda was filed until the constructive reduction to practice that occurred on November 18, 2008.

“(4) Whether Ueda Teaches Away from Providing Play-list Information While Establishing a Connection Finally, Patent Owner argues that Ueda teaches away from providing “play-list information” at the same time as establishing a connection, because Ueda teaches successfully completing user authentication before transmitting the playlist. PO Resp. 52–53 (citing Ex. 1003 ¶¶ 56, 365, Fig. 25; Ex. 2001 ¶ 99). According to Patent Owner, “Petitioner’s argument fails to reconcile[] this ordering of Ueda, which would prevent implementation of the proposed combination with the SDP Standard, in which the playlist is transmitted as part of the ‘Session Initiation.’” Id. at 53 (citing Ex. 2001 ¶ 100). In its Reply, Petitioner argues that limitation 1g “does not require transmitting ‘play-list information’ ‘at the same time’ as authentication, but at a same time ‘the one or more connection control servers executes a process for guaranteeing a communication bandwidth . . . as a process for establishing the connection.’” Pet. Reply 23. Petitioner also argues that the ’427 patent also describes an authentication step before transmitting the play-list information. Id. (citing Ex. 1001, 12:56–13:13, 13:50–58, Fig. 4). We find Petitioner’s arguments persuasive, and we disagree with Patent Owner that claim 1 restricts the timing of user authentication. As Petitioner notes, user authentication occurs in the ’427 patent before the process of establishing a connection as depicted in Figure 5. See Ex. 1001, 12:36–55, Fig. 4 (user authentication occurs when user equipment 2 is powered-up); id. at 13:50–58 (SIP message A501, at the beginning of Figure 5, includes “user authentication success information”). But we find nothing in the claim language, itself, that requires any particular timing for authentication. Nor do we understand Petitioner’s motivation-to-combine argument to hinge on the timing of authentication. Thus, Ueda does not “criticize, discredit, or otherwise discourage” the claimed invention.

- Obviousness (§103) › Motivation to combine / reasonable expectation of success › HindsightDecided for petitioner
“We find Petitioner’s arguments persuasive. Petitioner does not rely solely on the SDP Standard for teaching the sending of play-list information, but also relies on Ueda, which discloses sending a playlist including an identification of main content, commercial content, and an output sequence, as we discuss in more detail below in the context of limitation 1h. See infra Section III.D.3(g). Petitioner relies on the SIP and SDP Standards for teaching that Ueda’s playlist, as with other data describing a session, may be formatted and transmitted as payload within a standard SIP message, for example using SDP fields. Based on the evidence of record, we find it persuasive that a person of ordinary skill in the art would have recognized SDP as a known way to format play-list information, since SDP has specific fields to convey the features of a playlist such as metadata and links to the content. See Pet. 50–52. Petitioner’s arguments are not based on improper hindsight bias. Although Petitioner argues that the SDP Standard “can” or “could” be used to format Ueda’s playlist, the evidence suggests that doing so would merely be “[t]he combination of familiar elements according to known methods,” and that kind of combination “is likely to be obvious when it does no more than yield predictable results.” KSR, 550 U.S. at 416. The evidence shows that is the case here. As such, the Petition relies on the predictable combination of the prior art according to known methods and on various motivations to combine the references (see Supra Sections III.D.1–2), not on the ’427 patent itself, for teaching the combination.” slip op. at 57

On this record, we agree with Petitioner that the proposed combination of Chalom and Aslan would predictably result in the teacher MLA generating motion vector fields for user gaze correction (i.e., first reference or editing instructions) that are passed to the student MLA, which subsequently generates motion vector fields (i.e., second reference or editing instructions) for further refining the received first reference data. Id. at 58. Consequently, we reiterate that because the proposed combination involves known elements performing their ordinary functions to produce a predictable result, a POSITA would have appreciated that the proposed combination is proper.4 After considering Patent Owner’s arguments, we find Petitioner has shown by a preponderance of the evidence that the proposed combination of Chalom and Aslan is sufficiently supported by the requisite motivation to teach limitations 1[D] and 1[E].” slip op. at 40

“Because Chalom explicitly indicates that its RFC can be trained using any suitable techniques(s) including compressing the classifier, we agree with Petitioner that a POSITA would have looked to Aslan’s teacher-student architecture that proposes compressing large models such as Chalom’s RFC into smaller models so they can be more readily deployed on computing devices with limited resources. Pet. Reply 11–12. As correctly noted by Petitioner, the experts of the parties agree that both Aslan and Chalom involve classifiers. More particularly, as acknowledged by Patent Owner’s representative during the hearing, compression is desirable for Chalom’s RFC. See Tr. 56:21–57:4. Accordingly, we agree with Petitioner that a POSITA would have looked to a similar compression operation of classifiers in Aslan for training a more compact MLA at runtime or offline. Pet. Reply 11–12. For these same reasons, we find unavailing Patent Owner’s argument that Chalom and Aslan are directed to different objectives or techniques. Further, we do not agree with Patent Owner’s argument that replacing Chalom’s large RFC with Aslan’s teacher-student MLA pair would have rendered the ensuing system more complex, and thereby inefficient.

“been obvious to implement a VPN tunnel with Drell’s system. Patent Owner does not dispute that Elliott specifically discloses a VPN tunnel that is consistent with the district court construction. Petitioner establishes persuasive motivation for employing Elliott’s well-known VPN tunnel in Drell’s conferencing system with a reasonable expectation of success. See Pet. 24–25, 32–33. For example, as noted above, Petitioner contends that Drell teaches that its “network 106 may comprise a packet switched network, such as the Internet” (Pet. 42 (quoting Ex. 1008, 3:33–38)), and Elliott “teaches communicating conferencing ‘media stream (e.g. voice, fax, data, video, etc.)’ over ‘the public Internet’ using ‘virtual private network (VPN) . . . IP-tunneling.’” (id. (quoting Ex. 1007, 2:66–3:1, 4:6–34, 6:43– 54)). Based on these teachings, Petitioner contends that it would have been obvious to employ a VPN tunnel in Drell’s network as Elliott teaches, in order to “provide Drell with secure communications as the communications traverse Internet network 106” between conference endpoints (rendering the endpoints/appliances secure). See id. at 42–43 (citing Ex. 1003 ¶ 236, “network 18 can be either a public or a carrier supported virtual private network (VPN) or local area network (LAN) which uses IP or IP-tunneling.” Reply 12 (citing Ex.1007, 4:28–32). Therefore, as Petitioner also argues “[t]his network allows for secure transmission of audio data via a VPN tunnel.” Id. (citing Ex. 1003 ¶¶ 234–236). Petitioner also persuasively explains that a POSITA would have understood that VPNs are beneficial because they reduce the need to lease private data lines, which reduces or avoids the costs for implementing a private network by communicating securely over the Internet. [Ex. 1003 ¶ 168] Indeed, the combination of Drell and Elliott is merely the ordinary use of a common technique (using VPN tunneling for conferencing data) in the similar conferencing system of Drell to yield predictable results of (1) securing the transmitted data, and (2) reducing or avoiding costs associated with leasing private data lines.

See PO Resp. 24. Moreover, Patent Owner’s arguments attack the references individually without addressing Petitioner’s specific reliance on different teachings in the references, where the Petition relies on Drell as teaching transmitting audio between remote parties and supplements that with the audio mixing teachings of Knappe, as summarized above. See Pet. 44–48. In addition, contrary to Patent Owner’s arguments, as Petitioner notes and as discussed above, Elliott generally discloses audio and also securing the transmission of audio data with VPN tunnels.

Patent Owner’s arguments largely do not address Petitioner’s contentions and fail to address Petitioner’s arguments in support of the combination. In addition, Petitioner supports its arguments with citations to the references and credible declarant testimony from the vantage of a person of ordinary skill in the art, while Patent Owner’s arguments as to the interpretation of the references and motivations (or lack thereof) of a person of ordinary skill in the art are insufficiently supported by testimony from the viewpoint of a person of ordinary skill in the art or citation to the references.10 See PO Resp. 16–18. We find Petitioner’s interpretation of the references and motivation to combine more persuasive than Patent Owner’s insufficiently supported attorney argument on these issues. Patent Owner also fails to explain how the alleged “fundamental” differences in Knappe and Drell have any bearing on how they are used in the proposed combination. See PO Resp. 16–18; Sur-reply 3–4. Rather, Patent Owner’s argument merely points out alleged differences between the references, while essentially ignoring their commonalities.

In the Sur-reply, Patent Owner clarifies that the citation should have been to paragraph 20 of Mr. Dye’s Declaration (Sur-reply n. 1), but, as discussed below, this testimony merely repeats arguments made in the Sur-reply. See Sur-reply 4–5. 11 “The test for obviousness is not whether the features of a secondary reference may be bodily incorporated into the structure of the primary reference . . . .

To the extent that Patent Owner is arguing that Drell and Knappe are not analogous art to the ’525 patent, we do not find this persuasive. As Petitioner argues, both references pertain “to the field of multiparty conferencing, including mixing data from Internet and PSTN conference endpoints.” Pet. 17 (citing Ex. 1008, code (54), 3:33–37; Ex. 1006, 3:41–51, 6:59–62; Ex. 1003 ¶¶ 148–149).

See PO Resp. 21–28; see also 37 C.F.R. 42.65(a) (“Expert testimony that does not disclose the 16 Patent Owner does not specifically address VPN Textbook in connection with claim 1 but does so in its arguments with respect to claim 8. PO Resp. 33–34; see infra § III.4.E.4. no weight.”). We find Petitioner’s interpretation of the references and motivation to combine more persuasive than Patent Owner’s insufficiently supported attorney argument on these issues. In addition, notwithstanding Patent Owner’s argument that “Knappe does not teach securing multi-party communication” (PO Resp. 19, 22), “securing multi-party communication” is not recited or implied in step [1.3.2].” slip op. at 41

RulingsFinal written decision- BurdenDecided for petitioner
“applicable evidentiary standard, Petitioner has the burden to prove unpatentability by a preponderance of the evidence. See 35 U.S.C. § 316(e); 37 C.F.R. § 42.1(d) (2022). “Preponderance of the evidence means the greater weight of evidence, evidence which is more convincing than the evidence which is offered in opposition to it.” United States v. C.H. Robinson Co., 760 F.3d 1376, 1383 (Fed. Cir. 2014) (internal quotations omitted). This Final Written Decision is issued pursuant to 35 U.S.C. § 318(a) and 37 C.F.R. § 42.73.” slip op. at 2
- Skill levelSkill level petitioner adoptedDecided for petitioner
“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. Cir. 1995) (citation omitted). The level of ordinary skill in the art also may be reflected by the prior art of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001). Considering the subject matter of the ’855 patent, the background technical field, the prior art, and Petitioner’s generally unopposed proposed definition of the skilled artisan, we apply the level of skill set forth above, which also is consistent with the testimony of Mr. Andrews (Ex. 1002 ¶¶ 27, 32–71). Regardless, neither party argues 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.” slip op. at 9
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededDecided for petitioner
“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. Cir. 2017) (stating 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))). “Petitioner does not believe that any term requires explicit construction to resolve the grounds presented.” Pet. 8. “Patent Owner agrees that none of the terms in the patent require an explicit construction to resolve the dispute between the parties,” and submits that “all of the terms should be given their plain and ordinary meaning in light of the surrounding claim language.” PO Resp. 5. Based upon the parties’ positions here and our consideration of the complete record before us, we conclude that it is unnecessary to interpret expressly any limitations for purposes of rendering our final decision in this case. See Nidec, 868 F.3d at 1017. That said, we note that the parties present various patentability arguments in this case that depend at least in part on attributing a particular interpretation to certain claim limitations. We discuss these interpretations in the context of the relevant limitations in our patentability analysis below in Section III.D.” slip op. at 11
- Claim Construction › Intrinsic evidence (Phillips canons) › Preamble limiting or notNot reached
“Neither Petitioner nor Patent Owner takes a position as to whether the preamble is limiting, nor does Patent Owner dispute that Hashimoto discloses such a “method,” generally. See Pet. 18–19; see generally PO Resp.; PO Sur-reply. Because we find that Petitioner’s cited disclosure from Hashimoto discloses a “method of determining location via a tracking device associated with an individual or an object to be located,” we need not determine whether the preamble is limiting. See Nidec, 868 F.3d at 1017.” slip op. at 19
