“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).

“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. See PTAB Consolidated Trial Practice Guide 40 (Nov. 2019)5 (“Opinions expressed without disclosing the underlying facts or data may be given little or no weight.”) (citing Rohm & Haas Co. v.

“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. The only disclosure of a comparison in Bose that we have been shown is the comparison of PowerTotal to PowerMax in step 303 of Figure 3, which Petitioner does not rely on to meet the “comparison” limitation in the claim. 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. We find, therefore, that Petitioner has not demonstrated that claim 1 is anticipated by Bose, nor has Petitioner demonstrated that to a person of ordinary skill, claim 1 would have been obvious in light of Bose.” slip op. at 25

“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.

“Patent Owner admits that Petitioner has not previously filed a petition for inter partes review of the ’887 patent. Opp. 12. Under Valve Corp. v. Electronic Scripting Products, Inc., IPR2019-00062, Paper 11 (PTAB April 2, 2019) (precedential), General Plastic may apply when parties that have a “significant relationship” file successive petitions against the same patent. Valve Corp., Paper 11 at 10. In Valve, the successive petitioners were found to have a significant relationship because they were “co-defendants in the District Court litigation and were accused of infringing” the patent being challenged before the Board. Id. Patent Owner admits it “is not aware of a close relationship between Petitioner and Copeland Comfort Control LP.” Prelim. Sur-reply 4. In fact, Copeland and Petitioner are not co-defendants. Consequently, there is no “significant relationship” between Petitioner and Copeland. Patent Owner argues that General Plastic Factors 2, 4, and 6 weigh against joinder. Opp. 14. The Director, however, recently determined that where “the first and second petitioners are neither the same party, nor possess a significant relationship under Valve, General Plastic factor one necessarily outweighs the other General Plastic factors” and that “exercising discretion to deny the Petition is not justified.” Videndum Production Solutions, Inc. v. Rotolight Limited, IPR2023-01218, Paper 12, 6–7 (PTAB April 19, 2024) (Decision Granting Director Review). Regardless of whether the other factors weigh against joinder or not, factor one “necessarily outweighs” the other factors. Consequently, we do not exercise discretion to deny institution or joinder in this case based on General Plastic.” slip op. at 17

- Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITAPlain and ordinary meaningDecided for patent owner
“We disagree with this argument because it is not consistent with the ’953 patent specification or the plain meaning of “replace.” Neither party requested a special construction of the term “replace.” We see no merit in Petitioner’s contention that the plain meaning of “replace” in Figure 32 does not require removal of the device being replaced. The contention that the plain meaning of “replace” does not require “removing” was explored with Petitioner’s counsel at the oral argument: THE BOARD: If you replace a player in a football game or baseball game, a new player goes in and replaces that player. You don't add a 12th, a 12th player or a 10th player to a baseball team. You replace the player that’s there with a different player. Isn’t that what replacement is all about? COUNSEL FOR PETITIONER: Your Honor, in that context, it absolutely is. Because there’s no other way to understand that. You know, but we’re not talking about baseball or people here obviously. Hearing Tr. 18:23–19:3 (emphasis added).” slip op. at 15
