Ex. 2009, 3–4 (Petitioner’s Preliminary Claim Construction Chart); Ex. 2010, 7 (Patent Owner’s Preliminary Claim Construction Chart). Patent Owner states in the Patent Owner Response that “[t]he parties now agree that the entire preambles of both claims 1 and 6 are limiting.” PO Resp. 17. In its Reply, Petitioner states that “whether the Board finds the phrase ‘service auto-configuration’” in the preamble to be limiting is “immaterial” because it “does not affect the analysis of whether the prior art cited in the petition invalidates [the challenged] claims.” Pet. Reply 5. At the oral hearing, Petitioner acknowledged that it does not dispute that the entire preamble of claims 1 and 6 is limiting. Tr. 20:25–21:17, 23:15–17.

“Based on the full trial record, we find that Petitioner has failed to meet its burden to show that Bernstein recites a “service auto-configuration” method as recited in the preamble of claim 1. As discussed above, the parties agree that the preamble of claim 1, including the “service auto-configuration method” language, is limiting. See § II.B, supra. As we explained in the Institution Decision, the Petition does not set forth a construction of “service auto-configuration method” or explain how the prior art discloses a “service auto-configuration method.” Pet. 11, 24; Inst. Dec. 32. Instead, the Petition merely explains how Bernstein teaches “a DOCSIS Provisioning of EPON (DPoE) system,” without explaining how it teaches a “service auto-configuration method.” Pet. 24 (citing Ex. 1005 ¶ 59). By failing to offer a construction of “service auto-configuration method” or explain how this limitation is met by the prior art, the Petition fails to show by a preponderance of the evidence that the prior art discloses or suggests this limitation.” slip op. at 34

“Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine. Given that Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1, we reverse the Board’s patentability determination as to that claim and vacate the Board’s judgment as to the remaining claims of the ’037 patent. Everstar II, 2025 WL 1501940, 4 (internal citations omitted). The Federal Circuit further noted Patent Owner’s secondary considerations arguments as to claim 1 and stated [t]he cited evidence consists only of a temporal connection between the introduction of Willis’s invention and the UL 588 standards, and deposition testimony of a single witness who seemingly disclaimed any connection between the two. This is not sufficient to rescue a claim as to secondary considerations. Id. at 4, n. 5 (internal citations omitted).

“arguments, we agree with Patent Owner’s proposed construction that requires the server to conduct a compatibility check. We start with the express claim language. Claim 10 recites: determining, by the server, applicable settings for the selected vehicle, the applicable settings being settings that are preferred to be set as identified from the user profile and are compatible with settings that are settable in the selected vehicle. Ex. 1001, 33:10–14 (emphases added). The express claim language requires that the server determine applicable settings.

“However, contrary to Dr. Almeroth’s testimony and Petitioner’s position, Xiao’s server already does not attempt to command vehicles to do things they cannot do. Xiao teaches that server 118 generates commands for command codes that exist and are settable in the vehicle. Ex. 1010 ¶¶ 102– 103. As such, if there is no corresponding automobile setting, then Xiao’s server would not list those command codes for retrieval and would not send a command based on that retrieved command code to control the automobile systems to achieve the operator’s desired settings because that command code is not in the database. Our understanding of Xiao is further supported by Dr. Almeroth’s testimony: By listing them in the table of automobile command code information 606, Xiao shows that there are particular settings compatible with particular automobiles and particular desired settings. Thus, Xiao demonstrates the necessarily present characteristic that certain settings (e.g., commands) are compatible with certain automobiles. Ex. 1009 ¶ 96 (emphases added). We note that Dr. Malek further explains “the nonsensical result achieved by the combination would be that Xiao’s server, at best, in response to the command request issued by the operator, could ‘look up’ a command code to apply a vehicle-specific setting to that automobile 112, only to find that there is ‘none.’” We agree with Dr. Malek that there is a “None” command code in Xiao’s database when Xiao’s database already stores settings that are known to be settable in a specific vehicle per the operator’s preferences. Ex. 2011 ¶ 135. Thus, based on the complete record, we determine that Petitioner has not demonstrated by a preponderance of the evidence that Xiao in combination with Hayashi render claim 10 obvious.” slip op. at 79

Mr. Lett further fails to explain how or why one would want to move Mahajan’s abstraction layer in the first place. Although Mahajan teaches that its system can operate in a distributed environment, based on the explicit disclosure of Mahajan and its examples, we do not understand “distributed” to mean that (i) the server processes can occur on client devices and (ii) that client processes can occur on server devices. See Ex. 1114 ¶¶ 51, 58, 60, 61, 76, 77.

We also find Dr. Wicker’s testimony credible when he explained that even if Mahajan’s abstraction layer were implemented on a server in a network as posited by Petitioner, it still would not result in the claim mapping proposed by Petitioner.

“Overall, we find Dr. Holberg’s testimony particularly telling, and not very persuasive, with respect to combining Oliaei and Vittoz. Dr. Holberg makes clear that a person of ordinary skill in the art would have analyzed Oliaei’s circuit, and in particular any switches that were of concern, before implementing charge injection compensation circuitry. See, e.g., id. at 25:8– 26:22 (Dr. Holberg describing for a pacemaker amplifier circuit he designed “I definitely did a lot of analysis because I had to deal with the DC value, so I did a lot of analysis on the charge injection impact.”). Dr. Holberg did not, however, provide any technical analysis or circuit performance simulations in his original declaration showing that Oliaei would benefit from Vittoz’s charge injection compensation circuitry. See Ex. 1002 ¶¶ 200–218. Also, in his original Declaration, Dr. Holberg testified that “[a] POSITA could have combined the common-mode circuit and the common-mode feedback circuit of Oliaei with the impedance matching circuit of Vittoz using the known modeling methods disclosed by Vittoz.” Ex. 1002 ¶ 202 (citing Ex. 1012, 101–105, Fig. 7). The mere fact that the prior art reference could be modified does not satisfy the requirements for a finding of obviousness. Indeed, even if Vittoz’s charge injection circuit could be implemented in Oliaei’s CMFB circuit, and “a POSITA would recognize Vittoz’s balancing capacitors and dummy switches would operate in substantially the same way, whether in the system disclosed by Vittoz or the system disclosed by Oliaei,” as Dr. Holberg testifies, this does not explain persuasively why a person of ordinary skill in the art would have added Vittoz’s charge injection circuitry into Oliaei’s CMFB circuit.” slip op. at 44

“Considering all the evidence of record, we agree with Patent Owner that Petitioner has not asserted sufficient rationale for the combination of Oliaei and Vittoz. See PO Resp. 51–77; Ex. 2002 ¶¶ 71–103. Petitioner alleges similarities between Oliaei and Vittoz and that the resulting combination, based on a desire to compensate for charge injection, would have predictably yielded the claimed system. Pet. 77–81. The arguments and evidence are deficient, however, for several reasons. First, as discussed above, we considered Petitioner’s assertion that a person of skill in the art would consider charge injection as a reason to look to Vittoz. Pet. 77. The evidence from both Dr. Holberg and Dr. Kinget is clear, however, that charge injection is not always necessary or compensated for in every switched capacitor circuit. See, e.g., Ex. 2003, 39:16–18 (Dr. Holberg stating that “I’m sure I’ve never put charge compensation circuitry on every switch. I’m sure of that.”). Second, Petitioner’s evidence including simulations of the combined Oliaei and Vittoz teachings, together with Patent Owner’s simulation evidence, illustrate that there are no clear-cut improvements in Oliaei’s circuit. The experts’ simulations, as a whole, show that by choosing particular parameters Oliaei’s circuit performance might be improved, and choosing other reasonable parameters would not improve circuit performance. With results of the simulations going both ways, the evidence is not persuasive that the combination would have yielded a predictable result. Third, the alleged rationale of adding charge injection compensation does not address sufficiently the reason a person of ordinary skill in the art would combine the relevant teachings of Oliaei and Vittoz. Oliaei expressly discloses that the inventors undertook “numerous” simulations to address issues of clock-feedthrough glitches, i.e., charge injection, and that the results showed no impact of charge injection on system performance. Ex. 1007 5:17–32. Without sufficient explanation, Petitioner and Dr. Holberg have failed to present a persuasive rationale for the alleged combination.” slip op. at 49
