“350 receiving a request for a listing of “services” from a gateway device and provisioning one or more tunnel servers has not been shown to teach generating “a list of available servers.” There is no persuasive evidence to support Petitioner’s assertion. Petitioner relies on unsupported argument because, at best, Hankins discloses gateway devices 311 and 321, each of which is located in different logical broadcast domains, requesting services from one another. Ex. 1005, 12:9–16. This particular disclosure, however, does not appear to implicate the functionality of Hankins’s controller 350, much less result in controller 350 generating a list of available tunnel servers that would allow gateway devices 311 and 312 to exchange a listing of “services” therebetween. Petitioner’s reliance on Hankins’s controller 350 provisioning additional tunnel servers both to improve performance and without human intervention fares no better. Ex. 1005, 25:45–55. There is no indication in Hankins that this provisioning performed by controller 350 is done in response to receiving a request for a list of available tunnel servers from either gateway device 311 or 312.” slip op. at 20

“Based on the plain language alone, there are “end-to-end tunnels” which “connect[] the first device and the second device” of the network system. In addition, “the person of ordinary skill in the art is deemed to read the claim term not only in the context of the particular claim in which the disputed term appears, but in the context of the entire patent, including the specification.” Phillips, 415 F.3d at 1313. As already noted, the parties appear to agree that the specification does not define explicitly an “end-to-end tunnel.” In describing Figure 33 of the ’505 patent, reproduced above in Section I.D.2, the specification describes Figure 33 as illustrating “GVN Tunnel from LAN to EDP to SRV_AP to EPD to LAN. This variation illustrates an end-to-end GVN tunnel(s) between edges of two LANs via one SRV_AP.” Ex. 1001, 33:8–11 (emphasis added). The specification further describes Figure 33 as showing one tunnel between EPD-1 and AP-1. This is joined to a second tunnel between AP-1 and EPD-2. There are three neutral hops within the Third Layer of the GVN represented by NH1, NH2, and NH3 as compared to the 13 hops on the base Internet between EH3 and EH15. Id. at 33:15–19. This disclosure shows the end-to-end GVN tunnel has two hops, one between EPD-1 and AP-1, and one from AP-1 to EPD-2. The intermediate connection at AP-1 teaches the tunnel may be interrupted, contrary to Patent Owner’s assertion that Figure 33 of the ’505 patent supports a construction requiring the tunnel to be “uninterrupted.” See PO Resp. 9–10; see also Section II.D.2 below (addressing Patent Owner’s “uninterrupted” argument).” slip op. at 19

“Patent Owner’s assertion that an “intermediate tunnel” is not an “endto-end tunnel.

Given our claim construction supra, we find Hankins’s tunnels are “end-to-end tunnels” even if they are made of separate segments. Based on our final construction, and for the reasons discussed in Section II above, on this complete record we find that Petitioner has shown that Hankins teaches or suggests limitation 1.3. For completeness, we have reviewed Petitioner’s arguments and evidence explaining how Hankins alone or in combination with Munger teaches the remaining limitations of claim 1, and we agree with and adopt Petitioner’s analysis.

“of oval-shaped void 25 in Cooney is in a “pinched off region” as claimed.

Pet. 35 (citing Ex. 1005 ¶ 59; Ex. 1002 ¶¶ 167–169). Thus, according to Petitioner, the void’s shape will be similar to the torpedo shape of the via—tapering out on the top half and tapering in on the bottom half. Id. In our view, Petitioner provides a technical reason, supported by testimony, why the bottom of the void will be in the identified pinched-off region of the torpedo-shaped via in Cooney. See id. at 35–38. Patent Owner’s arguments do not address Petitioner’s technical analysis and instead focus on the precision of Cooney’s drawings. See Prelim. Resp. 8–12. Given Petitioner’s technical analysis, however, the precision of Cooney’s drawings is not determinative. Further, Patent Owner’s argument that “void 25 is localized to [the middle portion of the via] and sealed off from the tapered . . . section” also misses the fact that the middle portion of the via still has the torpedo shape (it is the inflection point of where it goes from wider to smaller).

Although we do not reject Petitioner’s declarant’s definition, we also do not adopt it as the meaning of “cascaded transistors” at this time, absent the parties’ proposal that we do. According to the ’886 patent, transistors simply “coupled in series” are “cascaded.” Ex. 1001, 6:50–51. We use this disclosure to guide our analysis. Reviewing Figure 7 of Okashita, we see a configuration of transistors 1 and 2 that appears, on this record, to be coupled in series. When transistor 2 acts as a shunt for transistor 1, i.e., when the threshold voltage of transistor 2 has been overcome, then current flows through transistor 1, through transistor 2, and then to ground.

“review. See 35 U.S.C. § 314 (2024); 37 C.F.R. § 42.4(a) (2023). Under 35 U.S.C. § 314(a), we may not authorize an inter partes review unless the information in the petition and the preliminary response “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.”” slip op. at 2
- Skill levelSkill level petitioner adoptedDecided for petitioner
“Pet. 7 (citing Ex. 1003 ¶ 24). Patent Owner does not comment on Petitioner’s proposal nor does it propose a level of ordinary skill. Prelim. Resp. 25. At this stage, the level of ordinary skill is not at issue. Petitioner’s undisputed definition is supported by the testimony of its experts and is consistent with the ’107 patent and the asserted prior art. Accordingly, for purposes of this Decision, we apply Petitioner’s articulation.” slip op. at 15
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededOther
“We construe only those claim terms that require analysis to determine whether to institute an inter partes review. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those 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)). Neither party proposes any term for express claim construction. Pet. 20; Prelim. Resp. 24. We determine that no express construction of any claim term is necessary for purposes of this Decision.” slip op. at 16
- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation not foundNot shown unpatentable
“A “motivation to combine may be found explicitly or implicitly in market forces; design incentives; the ‘interrelated teachings of multiple patents’; ‘any need or problem known in the field of endeavor at the time of invention and addressed by the patent’; and the background knowledge, creativity, and common sense of the person of ordinary skill.” Perfect Web Techs., Inc. v. InfoUSA, Inc., 587 F.3d 1324, 1328–29 (Fed. Cir. 2009) (citing KSR, 550 U.S. at 418–21). While common sense might form a basis for showing limitation 13(e), Petitioner does not allege reliance on common sense or any other motivation to combine. We are not “free to adopt arguments on behalf of petitioners that could have been, but were not, raised by the petitioner during an IPR.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1381 (Fed. Cir. 2016).” slip op. at 24

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion. They are a guide to the decision, not the decision. Confirm every one against the court's own text before relying on it. Outcomes read from the patent owner’s side. Party names are extracted from the decision and are missing on about 900 short Director denials and scans, which carry the trial number instead.
