      “Under 35 U.S.C. § 324(a), a post-grant review may be instituted only if “the information presented in the petition . . . demonstrate[s] that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” Post-grant review is available for patents that issue from applications that at one point contained at least one claim with an effective filing date on or after March 16, 2013. See Leahy-Smith America Invents Act, Pub. L. No. 112-29, 125 Stat. 284 (2011) (“AIA”), §§ 3(n)(1), 6(f)(2)(A). After considering the briefing and the evidence of record, for the reasons set forth below, we determine that Petitioner has shown that the ’437 patent is eligible for post-grant review and that it is more likely than not that at least one challenged claim of the ’437 patent is unpatentable under § 324(a). Accordingly, we institute a post-grant review of all challenged claims of the ’437 patent.” slip op. at 2

      “Here, Patentee Sciencons AS filed a statutory disclaimer of claims 10 and 34 of the ’437 patent. Ex. 2001; Prelim. Resp. 43. Based on our review of Exhibit 2001 and the Office’s public records, we find that the disclaimer of claims 10 and 34 complies with the above-listed requirements of 37 C.F.R. § 1.321(a). Accordingly, we treat claims 10 and 34 as having never been part of the ’437 patent. See Vectra Fitness, Inc. v. TNWK Corp., 162 F.3d 1379, 1383 (Fed. Cir. 1998) (“This court has interpreted the term ‘considered as part of the original patent’ in [35 U.S.C.] § 253 to mean that the patent is treated as though the disclaimed claims never existed.”).

      “Petitioner contends that: A person of ordinary skill in the art (“POSITA”) in the field of the ’749 patent in March 2004 would have been someone with at least a few years of experience in knit materials and knitting methods and machines that can be used in making footwear, or a bachelor’s degree in textile-related sciences, engineering, or industrial product design, or equivalent academic or work experience, including in the footwear industry. EX1002, ¶68. Such a person of ordinary skill would have at least a general understanding of general construction processes and materials used in the manufacturing process of fabric-based articles. For individuals with a lower educational level, a person could still be of ordinary skill in the art provided that person’s working experience compensates for any such lower educational level, or vice versa. See id. Pet. 23–24. Patent Owner states that, “[f]or purposes of this Preliminary Response, Nike applies Skechers’ definition for a person of ordinary skill in the art.” Prelim. Resp. 14. Petitioner’s definition is consistent with the level of ordinary skill reflected in the prior art references of record. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “For the foregoing reasons, the underlying premise of Serendia’s arguments here and in the ’386 IPR remains substantially the same. Thus, for the same reasons discussed in our decision instituting the ’386 IPR, we find that EndyMed demonstrates a reasonable likelihood of prevailing with respect to at least one of challenged claims 1–29 of the ’836 patent. See ’386 IPR, Paper 18. That is not to say, however, that Serendia may not ultimately persuade us at trial of the deficiency of EndyMed’s showing based on a preponderance of the evidence.” slip op. at 13

    • Obviousness (§103) › Objective indicia / secondary considerations › NexusObjective indicia no nexusDecided for petitioner

      “evidences nonobviousness for four different patents. In this situation, a presumption of nexus is appropriate only if patent owner demonstrates that the claims of all four patents “generally cover the same invention.” See Fox Factory, 944 F.3d at 1377 (“Where a product embodies claims from two patents, a presumption of nexus can be appropriate only if the claims of both patents generally cover the same invention.”). “The same evidence of secondary considerations cannot be presumed to be attributable to two different combinations of features.” Id. at 1378 (citation omitted). “In such situations, the patentee retains the burden of proving the degree to which evidence of secondary considerations tied to a product is attributable to a particular claimed invention.” Id. (citation omitted). Here, Serendia does not demonstrate that the four different patents cover the same invention. See Prelim. Resp. 59–74. Indeed, Serendia does not address U.S. Patents 9,775,774, 9,320,536, and 10,869,812 at all. See id. That Serendia separately sought patent protection for each of these four patents suggests that these patents do not generally cover the same invention. Cf Fox Factory, 944 F.3d at 1378 (“The same evidence of secondary considerations cannot be presumed to be attributable to two different combinations of features.”). We made a similar determination in the ’386 IPR. See, e.g., ’386 IPR, Paper 18 at 38 (“Patent Owner fails to set forth which patents ‘generally cover’ the Sylfirm X device.” (citations omitted)).” slip op. at 12

      “We disagree with Serendia. EndyMed need not justify its delay where, as here, EndyMed satisfies the joinder requirement of filing the petition within one month of our institution of trial in the ’386 IPR. See 37 C.F.R. § 42.122(b); see also 37 C.F.R. §§ 1.7(a), 42.1(a). Indeed, by rule, EndyMed could not have filed the instant petition prior to institution of the IPR it was seeking to join. See 37 C.F.R. § 42.122(b) (“Any request for joinder must be filed . . . no later than one month after the institution date of any inter partes review for which joinder is requested.”) (emphasis added). And, although there is a one-year statutory bar from the date of service of a complaint alleging infringement for requesting inter partes review, that bar does not apply to a request for joinder. See 35 U.S.C. § 315(b). Thus, despite being filed more than one year from the service date of Serendia’s complaint alleging infringement of the ’836 patent, EndyMed’s petition and motion are nonetheless timely. Serendia also argues that joinder should be denied due to duplicative efforts with the parallel Delaware litigation, which involves the same parties and patent as here. See PO Opp. 3–4. That argument fails for the simple reason that EndyMed submits a Sotera stipulation, agreeing not to pursue in the Delaware litigation the same grounds that are asserted in the petition here or any grounds that reasonably could have been raised here. See Pet. Reply 1–2. A Sotera stipulation mitigates concerns of duplicative efforts, and we decline to discretionarily decline institution where a petitioner makes such a stipulation. See Katherine K. Vidal, Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (June 21, 2022) (“Director Memo”), at 3, 7–8.

      “As set forth in the Director’s Memorandum, Interim Procedure for Discretionary Denials in AIA Post-Grant Proceedings with Parallel District Court Litigation (dated June 21, 2022), at 7, available at https://www.uspto.gov/sites/default/files/documents/interim_proc_discretion ary_denials_aia_parallel_district_court_litigation_memo_20220621_.pdf, the [Patent Trial and Appeal Board] will not discretionarily deny institution of an IPR . . . in view of parallel district court litigation where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition. Petitioner’s stipulation (Ex. 1041) satisfies the language from the Director’s Memorandum quoted above. Additionally, we do not see an issue with ambiguity in Petitioner’s stipulation. Specifically, following joinder, this IPR (i.e., IPR2024-01068), which is based on the Petition at issue here (i.e., the Petition filed by NXP), will still be pending even though Petitioner will be joined to IPR2024-00936. Thus, the “IPR from this [P]etition” will be “pending,” which satisfies the language of Petitioner’s stipulation and precludes the actions stated therein. Further, to the extent there was any potential ambiguity, that ambiguity is resolved by Petitioner’s representations in e-mail correspondence (Exhibit 3001), as noted above. Therefore, we need not analyze each Fintiv factor to reach the determination that we will not exercise our discretion to deny institution in view of the parallel litigation.” slip op. at 8

    • 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.

      “Regarding the “first static unidirectional electric drift field to aid the movement of minority carriers” limitation, Petitioner relies on the parent file history and cited references, arguing that “Payne’s downward-sloping graded-dopant concentration aids the movement of minority carriers from the surface layer to the substrate to the same extent to which Applicant relied on the prior art and admitted to the Patent Office that such carrier movement would occur under the same scenario.” Pet. 23. Petitioner also asserts that the direction in which carriers are forced with the concentration profile disclosed in Payne is downward, toward the substrate and away from the surface. Pet. 23–28 (quoting and citing Ex. 1046, 237–238, 253–254, 289– 290; citing Ex. 1003 ¶¶ 95–106; Ex. 1005, 5:7–17, 5:44–55; Ex. 1009, 2:11– 16, 2:67–3:18, Fig. 2; Ex. 1010, 2:27–32, 5:14–22; Ex. 1013, 431; Ex. 1030, 24).

      “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.

      “under the pre-AIA version of 35 U.S.C. § 112, first paragraph and found that “movement of minority carriers is affected by multiple forces and fields” and that “it does not appear that simply the presence of ‘a unidirectional drift field’ in itself can achieve ‘drawing all minority carriers from said surface layer to said substrate.’” Ex. 1016, 289 (emphasis added). Patent Owner responded with the following argument: [A] unidirectional drift (electric) field necessarily affects all the present minority carriers in the same way - moving all minority carriers in the same direction because of the unidirectional drift due to the existence of the electric field. See “Physics and Technology of Semiconductor Devices,” A.S. Grove, pp. 224– 225, John Wiley and Sons, Inc., New York, 1st Edition 1967 (“This same electric field will then be of such direction as to aid the motion of injected holes. Thus the injected minority carriers will now move not only by diffusion but also by drift due to the existence of this electric field.”). Depending on the particular slope of the graded concentration of dopant, all minority carriers are either swept “down” (from the surface layer to the substrate) or “up” (from the substrate to the surface layer). See Applicant’s Figs. 5(b) and 5(c). Id. Patent Owner further argued that the Examiner’s finding appears to not consider that the graded dopant concentration itself creates a “built-in” electrical field that forces the movement of carriers into a particular direction, whereby the “direction” of the electrical field and the resulting direction of the carrier movement depends solely on the slope of the graded concentration of dopant. With regard to the existence of a “built-in” electric field created by a graded dopant density, . . . this inherent “built-in” unidirectional electric field is the additional parameter for ensuring that all minority carriers are being moved in one direction and which parameter the Office Action deemed to be missing from the disclosure. Id. at 289–90 (emphases added). Also, “without conceding its position on this issue,” Patent Owner amended claims to eliminate reference to “all carriers” and instead, refer to “carriers.” 13 Id. at 290. 4. Analysis of Claim 1 At this stage of the proceeding, we determine that Patent Owner’s statements made during prosecution of the ’195 patent contradict its arguments in the present proceeding.
