Patent Owner does not dispute and applies Petitioner’s proposed level of skill. PO Resp. 6. We find that Petitioner’s proposal is reasonable and consistent with the ’832 patent specification and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundDecided for petitioner

      “Thomason are in the same field of endeavor. Thomason describes a camera and method for correctly orientating pictures from the camera. See, e.g., Ex. 1004 ¶¶ 1, 2 29–40, Figs. 3a–3b. In particular, Thomason is interested in rotating and cropping images to reduce the effect of poor orientation. Pet. 9 (citing Ex. 1004 ¶¶ 2, 34, 36). Pacurariu likewise describes aligning and resizing/cropping of a captured image to correct poor orientation. See, e.g., Ex. 1005 ¶¶ 1, 3, 45–56, Figs. 5A–5C. The preponderance of the evidence also supports that a person having ordinary skill in the art would have had reason to combine the Pacurariu’s teachings with Thomason to predictably improve Thomason. Thomason teaches correct rotation of video data and makes use of rotation sensor to correct rotated images. Pet. 19–21 (citing, e.g., Ex. 1004 ¶¶ 4, 27, 29, 35; Ex. 1002 ¶¶ 76–77). Pacurariu similarly uses sensors and measures tilt angle of the camera. Id at 21–22 (citing, e.g., Ex. 1005 ¶¶ 51–52, Fig. 6; Ex. 1002 ¶ 78). Pacurariu further teaches that its tilt data angle can be stored for each “video frame.” Id. at 22 (citing Ex. 1005 ¶ 52). Petitioner, with support from credible testimony of Dr. Katsaggelos, explains how the teachings of Thomason and Pacurariu could be successfully combined. Id. at 23 (citing, for example, Ex. 1002 ¶ 81). A person of ordinary skill in the art could have known that Thomason’s system could be improved by saving rotation data for each video frame and correcting images on a frame-by-frame basis. Id. at 23–24. The testimony of Dr. Katsaggelos is credible in this regard. Ex. 1002 ¶¶ 80–81. Petitioner and Dr. Katsaggelos explain the references’ teachings and, based on these teachings, assert that a person having skill in the art would have had reason to combine with reasonable expectation of success based on those teachings. Reason to combine may properly come from the references themselves. KSR Int’l Co., 550 U.S. at 418 (explaining reason to combine may come from “interrelated teachings of multiple patents”). Based on the evidence presented, Petitioner establishes by a preponderance of the evidence that a person having ordinary skill in the art would have had reason to combine the teachings of Thomason and Pacurariu with a reasonable expectation of success. Ex. 1002 ¶¶ 76–81, 89–92; Ex. 1004 ¶¶ 4, 8–9, 27, 29, 35; Ex. 1005 ¶¶ 26, 41, 46, 51–52, 55–57, Figs. 6, 7.” slip op. at 27

Zaxcom, Inc., IPR2018-01129, Paper 33 at 33 (PTAB Jan. 24, 2020) (precedential). We first consider whether Patent Owner has demonstrated “that its products are coextensive (or nearly coextensive) with the challenged claims,” resulting in a rebuttable presumption of nexus. Id. at 33. If not, that “does not end the inquiry into secondary considerations”; “the patent owner is still afforded an opportunity to prove nexus by showing that the evidence of secondary considerations is the ‘direct result of the unique characteristics of the claimed invention.’” Id.

      “In our Institution Decision in IPR2024-01357, we analyzed claim 1 of the ’678 patent in light of Basin-2007 and Basin-2005. ’1357 IPR, Paper 17, 23–28. We concluded, after reviewing the arguments presented there, that “Petitioner has demonstrated a reasonable likelihood of proving that the combined teachings of Basin-2005 and Basin-2007 render claim 1 unpatentable as obvious.” Id. at 28. In this proceeding, Petitioner has presented a challenge to claim 1 based on those same references that it represents is a “verbatim” copy of its previous challenge to claim 1 in the ’1357 IPR. Pet. 1–2, 28–35. Petitioner supports its challenge with expert testimony. Ex. 1002 ¶¶ 107–125.7 Patent Owner has not submitted a response on the merits of this challenge. For the purposes of this Decision, and for the reasons given in the Petition, we adopt the analysis in our Institution Decision in the ’1357 IPR (at pp. 23–28), where we determined that Petitioner has demonstrated a reasonable likelihood of prevailing on its obviousness challenge to claim 1 based on Basin-2005 and Basin-2007. Turning now to Petitioner’s challenge to claim 11, Petitioner relies on Basin-2007 and Stokes for the particle size limitations added to claim 1 by that dependent claim. Pet. 35–39. Thus, Petitioner asserts that “Basin-2007 discloses a light scattering material with an average TiO2 particle size that is ‘sub-micron’ (less than 1000 nm).” Id. at 37 (citing Ex. 1005 ¶ 5). 7 Exhibit 1002 appears to be a duplicate copy of Dr. Doolittle’s declaration from the ’1357 IPR. Petitioner concludes, “Basin-2007 renders obvious claim 11 by literally disclosing the selection of average particle sizes that preferentially scatter blue light.” Id. Further, “to the extent that the claim language ‘an average particle size that is selected such that [it preferentially scatters blue light]’ requires an average particle size selected for that reason (rather than an average particle size that leads to that outcome), this claim element is rendered obvious by Stokes.” Id. at 38 (citing Doolittle Decl. ¶ 45) (alterations in original). Petitioner explains that “Stokes explicitly discloses the selection of an average particle size ‘such that the particles preferentially scatter blue . . . LED light as compared to yellow . . . light from the luminescent material.’” Id. at 38 (citing Ex. 1008, 7:1–4) (alterations in original). Petitioner provides a motivation for combining Stokes with Basin- 2007 with a reasonable expectation of success. Pet. 38–39. Petitioner explains that “[t]o the extent that claim 11 is understood to also claim the basis for selecting a particular average particle size, a [person of ordinary skill] would have had reason to use such a basis for selecting average particle size as taught by Stokes.” Id. at 38 (citing Doolittle Decl. ¶¶ 46–48). Further, “a [person of ordinary skill] would have been motivated to apply this principle to Basin-2007, because it would increase the conversion of blue light to yellow light and improve the uniformity of the light source.” Id. at 39 (citing Doolittle Decl. ¶ 48). At this stage, Patent Owner does not provide an opposition to Petitioner’s evidence or arguments on the merits.

      “October 25, 2024, from counsel for Patent Owner, Patent Owner requested authorization to file “a request for adverse judgment against itself under 37 C.F.R. § 42.73(b).” Ex. 3003 (emphases added). Our Rule 42.73(b) states “A party may request judgment against itself at any time during a proceeding.” The Board granted Patent Owner’s request. Ex. 3003. Patent Owner then filed its “Request for Adverse Judgment Pursuant to 37 C.F.R. § 42.73(b).” Paper 11 (Request for Adverse Judgment). This Request, however, stated, in error, that Patent Owner requested “adverse judgment against Petitioner on claims 33-36, pursuant to 37 C.F.R. § 42.73(b)(4).” Id. (emphases added). Our Rule 42.73(b)(4) concerns “[a]ctions construed to be a request for adverse judgment.” 37 C.F.R. § 42.73(b)(4) (emphasis added). Subsection (b)(4) states one of the actions construed to be a request for adverse judgment is “[a]bandonment of the contest.” Id. The actions construed to be a request for adverse judgment, however, are never reached when a party states unequivocally that it requests “judgment against itself.” that the Request for Adverse Judgement is seeking adverse judgment against itself, not Petitioner.

      “We are persuaded and find for the reasons given that Petitioner fails to prove by a preponderance of the evidence that White teaches or suggests “receiving a bus workload for a communication bus and a first processing element workload for a first processing element based on an integrated circuit reaching a limit.” Patent Owner’s expert Dr. Brogioli testifies that “[t]he workload is a function of the demands imposed by, e.g., applications running on the system, and may or may not be subject to direct control, whereas the conditions under which that workload is processed are controlled directly.” Brogioli Decl. ¶ 66. We agree with Dr. Brogioli and find that White’s frequency and voltage monitoring and adjustments do not result in the power management logic receiving the bus workload as recited in claim element 4[a]. Id. ¶¶ 64–66. We find the testimony of Mr. Wyatt on this issue unconvincing. Wyatt Decl. ¶ 103. In support of his opinion that “monitoring the operating voltages and frequencies of the logic core 120A and common logic bridge 110 is monitoring the workload of those components,” he states: “It was well understood that operating frequency and voltage of a component reflect the activity and use, or workload, of that component.” Id. However, he does not provide any evidentiary support for this statement. We, therefore, give it little weight.

      “Nowhere does Petitioner or its expert point to an explicit disclosure in Bose of making a comparison of the claimed “bus workload and a bus workload threshold.” Instead, Petitioner relies on its expert’s opinion as to what a person of ordinary skill might have known, without any additional supporting evidence. See, e.g., Pet. 26 (“[A person of ordinary skill] would have understood global PMCU compares a workload threshold as exemplified by the predicted power and performance of each power mode and the monitored workload to select and adjust the power mode of a component” (citing Wyatt Decl. ¶¶ 54–55)). This opinion is not supported by the record.

Hearing Tr. 17:16–20. Also without proper support is Petitioner’s assertion that “a [person of ordinary skill] would have understood that in Bose, selecting or adjusting power mode for a component entails comparing a workload threshold, such as predicted power and performance associated with each power mode with real time statistics, such as the monitored workload of a component.” Pet. 26 (citing Wyatt Decl. ¶¶ 55–56). We determine that for the reasons given, Petitioner fails to demonstrate by a preponderance of the evidence that the claimed comparison element 1[g] of claim 1 is taught or suggested by Bose.

      “Having considered the arguments presented in the Petition, the Preliminary Response, and the evidence of record, we determine that Petitioner has demonstrated a reasonable likelihood of success in proving that at least one claim of the ’958 patent is unpatentable as obvious over the combination of Bigbee and Nguyen. Accordingly, we institute an inter partes review of all challenged claims (i.e., claims 1–8 and 13–22) on all grounds set forth in the Petition. Our determinations at this stage of the proceeding are based on the evidentiary record currently before us. This decision to institute trial is not a final decision as to the patentability of any claim for which we have instituted an inter partes review. See TriVascular, Inc. v.

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “Patent Owner asserts: A person of ordinary skill in the art of the subject matter of the ’958 patent would have the equivalent of a bachelor’s degree in Computer Science, Computer Engineering (or a related field) and approximately two years of work experience with computer architecture design. Additional education in the field could be substituted for industry experience, and vice versa. See Prelim. Resp. 3. The parties’ positions appear to be more or less the same. Based on the current record, we adopt Petitioner’s proposed level of ordinary skill in the art for purposes of this Decision, as it is consistent with the level of ordinary skill in the art reflected by the prior art of record. We note that our Decision would be the same under either party’s proposed construction.” slip op. at 9

      “At this stage of the proceeding, only terms that are in controversy need to be construed, and then only to the extent necessary to determine whether to institute 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))). After reviewing the parties’ evidence and contentions, we do not observe a dispute over the meaning of these terms that is necessary to resolve at this stage. Accordingly, we determine that we do not need to expressly construe any term for purposes of this Decision.” slip op. at 10

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted

      “Based on our review and consideration of the current record, we determine that Petitioner has sufficiently shown that the combination of Bigbee and Nguyen teaches the recited elements of limitation 19a for purposes of institution and has provided reasons sufficiently supported by factual underpinnings to combine the references with a reasonable expectation of success. Nguyen discloses, “[t]he present invention addresses mechanisms for combining recoverable and non-recoverable error handling mechanisms efficiently in FRC-enabled processors.” Ex. 1006 ¶ 9. Subsequently, Nguyen distinguishes recoverable from non-recoverable errors by treating non-recoverable errors differently from recoverable errors. Nguyen discloses, “If an error reaches error detector 140 from either core 120, recovery module 150 is activated to implement a recovery routine. Recovery can be implemented with relatively low latency by hardware, software, firmware or some combination of these.” Id. ¶ 22, Fig. 1. “However, an FRC error will be triggered if the corrupted data from one execution core and an uncorrupted version of the data from the other execution are allowed to reach FRC checker 130 before recovery module 150 is activated.” Id. Nguyen recognizes, “[s]ince FRC errors are not recoverable, reset module 160 resets the system, if FRC checker 130 signals an FRC error before the underlying parity/ECC error is detected.” Id. Nguyen further recognizes that, “[n]ot all FRC-errors are traceable to underlying parity/ECC or other correctible soft errors. For those that are, it is faster for error detector 140 to address the under lying soft error than for FRC-checker to address the FRC error that results when the corrupted data reaches FRC boundary 104.” Id. ¶ 23 (emphasis added). In this instance instead of the FRC-error being processed by the FRC checker 130 and the Reset module 160, the FRC error is directed to the Error detector 140 and eventually recovery module 150. See id. at Fig. 1. Nguyen also discloses, “the recovery routine triggered by error detector 140 provides greater system availability than the reset routine triggered by FRC checker 130” and “[e]xpanding the FRC boundary thus increases both the amount of logic that is duplicated for execution cores 120 and the flight time, during which detectable errors may be identified.” Id. ¶ 30, Fig 1; see Pet. 37. Nguyen further discloses, “[t]he former increases FRC protection, albeit through a reset mechanism” as shown in Figure 1, elements FRC Checker 130 and Reset Module 160. Ex. 1006 ¶ 30. “The latter increases the likelihood that errors identifiable through parity, ECC [error correction code] or similar core-specific protections are handled through recovery rather than reset” as shown in Figure 1, elements Error Detector, 140 and Recovery Module 150. Id. Additionally, Nguyen’s Figure 7, as discussed above, “is a block” slip op. at 33

Conclusion for Claim 1 Having reviewed the Petition and Preliminary Response, we determine that Petitioner has a reasonable likelihood of success in showing that the subject matter of claim 1 would have been obvious in view of Pham and Wu. E. Conclusion on the Merits of the Petition We have found that the Petition warrants institution based on Petitioner’s showings for claim 1. We have reviewed Patent Owner’s arguments about the other grounds, but they largely rely on the earlier unpersuasive arguments for claim 1. On whole, we determine that Petitioner has shown that the Petition warrants institution.” slip op. at 18

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Decided for petitioner

      “based on the related district court matters identified above. Opp. Mot. Join 4–12. Our analysis under Fintiv is guided by the USPTO Director’s Memorandum issued on June 21, 2022, titled “Interim Procedure for Discretionary Denials in AIA Post Grant Proceedings with Parallel District Court Litigation” (“Director’s Memo”). Pursuant to the Director’s Memo, we “will not discretionarily deny institution . . . where a petitioner presents a [Sotera] stipulation.” Director’s Memo at 3. Because Petitioner has offered a stipulation like in Sotera, i.e., to “not pursue in the copending district court litigation the specific ground asserted in the petition, or any other ground that was raised or could have been reasonably raised in an IPR (i.e., grounds that could have been raised under §§ 102 or 103 on the basis of prior art patent or printed publications)” (Reply Mot. Join 4–5), we do not discretionarily deny institution under Fintiv.” slip op. at 21

    • PTAB / AIA Trials › Discretionary denial › General Plastic (serial petitions)Decided for petitioner

      “factor one necessarily outweighs the other General Plastic factors.”) (Director Review). Patent Owner focuses its analysis on factor 5 and proposed factor 8. Id. at 13–15. As to factor 5, which looks for an explanation of the time between petition filing, we determine that Petitioner sufficiently explained the time between Cisco’s petition and its own when it noted that it merely filed its petition and request for joinder when the statute permitted it. Reply Mot. Join 6 (citing 37 C.F.R. § 42.122(b)). In particular, the statute requires the earlier petition to be instituted before joining a party. 35 U.S.C. § 315(c) (requiring joinder to be to instituted proceedings). Thus, the time elapsed between filings is motivated by the statutory and regulatory procedures. See also 37 C.F.R. § 42.122(b) (requiring the joinder motion to be filed “no later than one month after the institution date of any inter partes review for which joinder is requested”). As to proposed factor 8, we agree with Petitioner that the present situation does not apply. Reply Mot. Join. 6–7; see also Shenzhen, IPR2018-00761, Paper 15, 18–19 (Saindon, concurring) (“There are legitimate reasons why a petition may be filed after [a decision on institution)].”). Proposed factor 8 analyzes situations where a second petitioner strategically waits to file its petition to see what happens to an earlier filed petition. Shenzhen, IPR2018-00898, Paper 9 at 7. If both of the petitioners were sued at or around the same time, but one waits until the other goes first, it can lead to an inference that the delay in filing a different petition was to gain an unfair advantage. Id. at 14 (looking with disfavor on a wait-and-see strategy to use the first petition as a “test case”). That is not the case here, where the second petition is a copycat petition. The Petition here cannot be said to have been filed second in order to glean knowledge from the first petition because it is the same petition. Thus, we do not see this Petition as being a strategic attempt to use Cisco’s petition as a “test case,” and do not consider factor 8 to weigh toward denial. Finally, reviewing factor 6, we do not find that granting Petitioner’s motion to join would cause an undue burden on the Board. Petitioner is serving as an “understudy” and thus, from our perspective, Petitioner’s presence does not change the existing Cisco IPR. Patent Owner argues that if Cisco were to settle then Petitioner would continue the proceeding. Opp. Mot. Join. 15. We do not see this as an undue burden in this situation. Petitioner’s Motion for Joinder serves to lessen our burden (as well as Patent Owner’s) compared to the scenario of it filing its own unique petition. We do not see the present case as similar to the Apple case, in which a copycat joinder petition was denied. See Apple, IPR2020-00854, Paper 9. That case, in our view, turned on the fact that the petitioner had already filed a petition that was denied on the merits. See id. at 4 (“In effect, it would be as if [the petitioner] had brought the second challenge to the patent in the first instance,” and labeling this a “serial attack.”). The situation here is not analogous to the Apple case because this is Petitioner’s only petition against the ’436 patent. The Petition is not a “serial attack” on the ’436 patent, it is merely Petitioner’s statutorily required vehicle to join as a party to an existing petition. Accordingly, we do not find factor 6 to weigh towards denial. Reviewing the General Plastic factors as a whole, including proposed factor 8, we find no factors to weigh toward denial and decline to exercise our discretion to deny institution.” slip op. at 24
