“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.

“3. Analysis At this stage of the proceeding, we determine that Patent Owner’s statements made during prosecution of the ’195 patent appear to contradict its arguments in the present proceeding. See generally Prelim. Resp. Based on the present record, Patent Owner’s statements during prosecution support Petitioner’s argument tthat a graded dopant concentration is enough to teach aiding carrier movement in a particular direction. Patent Owner does not dispute that Kawagoe has a graded dopant concentration in the active region at this stage of the proceeding. Id. Patent Owner also does not dispute that Kawagoe’s transistor has carriers in the active region or that the graded dopant concentration of Kawagoe is lowered from the surface to the bottom substrate (Ex. 1007, Fig. 17). Id. At this stage of the proceeding, the evidence of record supports Petitioner’s position sufficiently to meet the reasonable likelihood threshold for institution. We decline to make further determinations, on this preliminary record, regarding the dispute surrounding this limitation, because the trial in the 00001IPR is the better proceeding in which to do so. Specifically, as compared to the preliminary phase of this case, the instituted trial in the 10 The examined claims of the ’195 patent generally recited “a unidirectional drift field drawing all minority carriers from said surface layer to said substrate.” Ex. 1016, 286.

TIMELINESS OF THE PETITION UNDER 35 U.S.C. § 315(B) Pursuant to 35 U.S.C. § 315(b), “[a]n inter partes review may not be instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 10– 30. However, 35 U.S.C. § 315(b) also provides that the one-year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b). Because the Petition is accompanied by a timely request for joinder (Paper 2) to the instituted proceeding (IPR2024-00017), which we grant as further discussed below, Patent Owner’s argument that the Petition is time-barred under 35 U.S.C. § 315(b) is moot, irrespective of whether Petitioner is in privity with time-barred entities.” slip op. at 5

“B. Whether to Join Petitioner as a Party to the Cirrus IPR Joinder may be authorized when warranted, but the decision to grant joinder is discretionary. See 35 U.S.C. § 315(c); 37 C.F.R. § 42.122. A motion for joinder should (1) set forth reasons why joinder is appropriate; (2) identify any new grounds of unpatentability asserted in the petition; (3) explain what impact (if any) joinder would have on the trial schedule for the existing review; and (4) address specifically how briefing and discovery may be simplified. See, e.g., Kyocera Corp. v. Softview LLC, IPR2013- 00004, Paper 15 (PTAB April 24, 2013). As the moving party, Petitioner bears the burden of proving that it is entitled to the requested relief. 37 C.F.R. § 42.20(c). As an initial matter, we find the Motion for Joinder meets the timing requirements of 37 C.F.R. § 42.122(b) because Petitioner filed it on April 4, 2024, no later than one month after the Cirrus IPR was instituted on May 1, 2024.” slip op. at 9

“5. “Aid the Movement of Minority Carriers” Patent Owner argues that the Petition fails to show that the applied prior art references disclose the claim limitations “requiring ‘aid the movement of minority carriers,’” as twice recited in claim 1. Prelim. Resp. 8. Patent Owner summarizes this dispute as follows: The challenged patent discloses and claims a semiconductor device with (among other things) a “drift layer having a graded concentration of dopants . . . [and] further having a first static unidirectional electric drift field to aid the movement of minority carriers.”[] The Petition should not be instituted, because (among other deficiencies) it fails to show that the prior art discloses the “aid the movement of minority carriers” claim limitation. Rather than pointing to anything in the prior art that would teach this claim limitation, the Petition assumes that any “graded concentration of dopants” would necessarily “aid the movement of minority carriers.” The Petition contains no analysis explaining why the “graded concentration of dopants” in the prior art meet the “aid the movement of minority carriers” limitation, apart from the fact that they are “graded concentration of dopants.” In other words, Petitioner reads the “aid the movement of minority carriers” limitation out of the claims completely. Id. at 1–2. Patent Owner includes additional details in support of its view that the asserted prior art fails to establish obviousness of the “aid carrier movement” limitations of claim 1. Prelim. Resp. 1–10.” slip op. at 8

RulingsInstitution decision- Parallel petitionsDecided for petitioner
“On the present record, we agree with Petitioner that the two petitions filed to challenge the claims of the ’222 patent will not substantially burden the Board or the parties. The petitions in IPR2024-00673 and IPR2024- 00674 challenge different claims, and those claims appear on the present record to have different claim scope, as Petitioner argues. Paper 3, 3–4 (arguing that claim 44, challenged in IPR2024-00674, recites “a ‘surface layer,’ a ‘single drift layer,’ and ‘at least one well region disposed in the single drift layer,’ which are not” recited in the claims challenged in IPR2024-00673); Ex. 1001, 4:39–8:39. In addition, there is little overlap between the prior art asserted in the two petitions, and what overlap there is—the use of Kawagoe in both petitions—is used in different prior-art combinations in each petition. Compare IPR2024-00673, Paper 4, 5 (asserting Kawagoe alone and in combination with Gupta or Silverbrook), with IPR2024-00674, Paper 4, 5 (asserting Kawagoe in combination with Sakai). Accordingly, we do not exercise our discretion to deny either of the petitions challenging the ’222 patent for being parallel petitions.” slip op. at 5

“instituted if the petition requesting the proceeding is filed more than 1 year after the date on which the petitioner, real party in interest, or privy of the petitioner is served with a complaint alleging infringement of the patent.” Patent Owner argues that the Petition is untimely under 35 U.S.C. § 315(b) because Petitioner is in privity with time-barred entities. Prelim. Resp. 16– 37. However, 35 U.S.C. § 315(b) also provides that the one year time bar “shall not apply to a request for joinder under subsection (c).” See also 37 C.F.R. § 42.122(b). Since the Petition is accompanied by a timely request for joinder (Paper 2) to the instituted proceeding (IPR2023-01244), which we grant as further discussed below (see infra § V), Patent Owner’s argument that the Petition is time-barred under 35 U.S.C. § 315(b) is moot, regardless of whether Petitioner is in privity with time-barred entities.” slip op. at 5
