“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.

“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.

Rather, we find that the state court is better suited to address the conduct of Linq3 of which Patent Owner complains. Accordingly, we leave these matters for the state court. To the extent Patent Owner seeks to pursue its argument that Linq3 is a real party in interest to Petitioner, even though no time bar under 35 U.S.C. § 315(b) has been asserted, Patent Owner may raise the issue of real party in interest again in its Patent Owner Response, and the parties may brief and argue the issue during trial.” slip op. at 10

“We disagree. First, we agree with Patent Owner that the fact pattern presented here is not the typical situation in which the factors from General Plastic are considered. In particular, this proceeding challenges claims of a different patent than the patents at issue in PGR2020-00084 and IPR2023- 01235. Challenging claims of different patents significantly distinguishes the facts here from those in General Plastic, and we decline Patent Owner’s invitation to extend General Plastic in this regard. Accordingly, we do not exercise our discretion to deny institution.” slip op. at 11

“Even assuming Linq3 is a real party in interest to Petitioner and assuming we may exercise our discretion to deny institution based on unclean hands (see Kavo Dental Techs, LLC v. Osseo Imaging, Inc., IPR2020-00659, Paper 10 at 19 (PTAB June 10, 2020)), Patent Owner essentially asks us to resolve multiple factual issues related to its contract dispute with Linq3 to justify denial of institution. See, e.g., Prelim. Resp. 1– 26. Many, if not all, of these issues appear to be involved in the contract dispute, which will be resolved by the Arizona state court. We are not in a good position to make determinations about these particular issues at this stage of the proceeding, on the limited record before us.

“5. Weighing the Graham Factors “Once all relevant facts are found, the ultimate legal determination [of obviousness] involves the weighing of the fact findings to conclude whether the claimed combination would have been obvious to an ordinary artisan.” Arctic Cat, 876 F.3d at 1361. On balance, considering the record presently before us, Petitioner has established a reasonable likelihood that it would prevail in showing that Irwin would have rendered the subject matter of claims 1–9 and 11–24 of the ’451 patent obvious to one of ordinary skill in the art at the time of the invention.” slip op. at 38
