      “Under 35 U.S.C. § 314(a), inter partes review may not be instituted unless the Petition “shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” Petitioner has established a reasonable likelihood of prevailing on its assertion that at least one of the challenged claims is unpatentable based on the grounds advanced here. We decline to deny the Petition on a discretionary basis as requested by Patent Owner.

The teachings in the prior art support the presently unrebutted testimony of Dr. Randall explaining why the POSA would have been motivated to modify Kim ’761’s copper foil to have the claimed TC(220) and ΔRz/Ra. Ex. 1003 ¶¶ 66–68, 71–74; Pfizer Inc., v. Sanofi Pasteur Inc., 94 F.4th 1341, 1348 (Fed. Cir. 2024) (“Where [a gap in prior art] includes a parameter not necessarily disclosed in the prior art, it is not improper to consider whether or not it would have been recognized as result-effective. If so, then the optimization of that parameter is ‘normally obvious.’”). Accordingly, we are not persuaded by Patent Owner’s argument that Petitioner failed to articulate a sufficient motivation to combine the references. To the contrary, the preliminary record presents a strong showing that the POSA would have been motivated to combine the references in the manner described in the Petition.” slip op. at 38

      “Thus, although both parties indicate that no claim construction is necessary at this stage of the proceeding, it is apparent that they disagree as to the meaning of “discrete carbon nanotubes.” While Petitioner appears to construe “discrete carbon nanotubes” as “nanotubes that are generally individually distinct” (Pet. 13), Patent Owner argues a more restricted construction requiring that “discrete carbon nanotubes” not be reacted with other components. Prelim. Resp. 3. The evidence relating to claim 10 In quotations from the Preliminary Response throughout this Decision, we have retained bolding and underlining added to the text by Patent Owner. construction that Patent Owner offers on the current record, however, does not address its proposed restriction. See id. at 9, n. 4, citing Ex. 1001, 3:9, 5:39–40 (“The ’649 Patent describes the ‘discrete carbon nanotubes’ as, for example, ‘individually dispersed’, ‘individualized carbon nanotubes’, ‘dispersed as individual nanotubes’, and ‘essentially discrete individual fibers, not entangled as a mass.’”). As discussed in Section II.D.2 below, we determine based on the record at this stage of the proceeding that Petitioner demonstrates sufficiently for purposes of institution that Sun discloses or suggests “discrete carbon nanotubes.” Therefore, we do not explicitly construe any claim terms in this Decision. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“we need only construe 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))). If either party intends to argue a claim construction at trial, however, including what is the ordinary meaning of a term, they should do so in a clearly designated section of their briefing. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 21, 2019) (“CTPG”), 46, 49 (available at https://www.uspto.gov/TrialPracticeGuideConsolidated); O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”).

    • PTAB / AIA Trials › §315(b) time barNot time barredDecided for petitioner

      “II. 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

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot reached

      “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.

Based on our review of the ’335 patent and the prior art of record, at this stage of the proceeding we determine that the definition offered by Petitioner comports with the qualifications a person would have needed to understand and implement the teachings of the ’335 patent and the prior art. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed.

      “As discussed above, however, we are persuaded, at this stage, by Petitioner’s argument that that Saxler teaches or suggests an operable enhancement-mode device. See § II.D.1.a.i, supra. Additionally, Patent Owner’s argument regarding modifications that “could be detrimental” to certain devices is not only speculation, but also comprised entirely of attorney argument. Finally, Patent Owner does not directly address Petitioner’s arguments and accompanying evidence that a person of ordinary skill in the art would have had reason to combine the teachings of Saxler and Yoshida to take advantage of simplified manufacturing steps and reduced costs. Based on the present record, Petitioner has sufficiently shown that Saxler and Yoshida disclose or suggest all of the limitations in claims 1, 3, and 4, and that a person of ordinary skill in the art would have had a reason to combine the teachings of Saxler and Yoshida with a reasonable expectation of success. Accordingly, we determine Petitioner has established a reasonable likelihood of prevailing on its challenge that claims 1, 3, and 4 are unpatentable as obvious in view of Saxler and Yoshida.

      “Claims Claim terms are generally given their ordinary and customary meaning, which is the “meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Phillips, 415 F.3d at 1313. Patent Owner does not present evidence that the ordinary meaning in the art of a “GaN layer” is “GaN gate material.” Indeed, the prior art of record discloses multiple GaN layers that do not appear to be “gate material.” Ex. 1006 ¶ 32; Ex. 1005 ¶ 74 (“the channel layer 20 is GaN”); Ex. 1008 ¶¶ 24–25 (noting that the buffer layer and semiconductor layer are GaN). Nor does Patent Owner contend that the term “compensated” requires or implies a particular orientation or location with respect to the gate contact. Thus, by itself, the term “compensated GaN layer” does not require a “compensated GaN gate material.” Rather, Patent Owner contends that given the placement of the “compensated GaN layer” above the barrier layer and below the gate contact, one of ordinary skill in the art would have understood that the claimed “compensated GaN layer” is a “compensated GaN gate material.” Prelim. Resp. 7. We are not persuaded by this argument, at this stage of the proceeding, because the prior art (Uemoto) discloses a compensated GaN layer that is above a barrier layer and below a gate contact, as recited in claim 1, and Patent Owner contends this layer is not a “compensated GaN layer.” Ex. 1006, Fig. 7; Prelim. Resp. 31–32. This tends to suggest that the placement of a “compensated GaN layer” above a barrier layer and below a gate contact, without more, does not necessarily indicate that said layer is part of the gate. In view of the foregoing, on this record, we determine that the language and structure of claim 1 does not support a construction requiring that the “compensated GaN layer” be a “compensated GaN gate material.”” slip op. at 11

      “stackable add-on layer” requires something more than just any type of layer that is directly or indirectly adhered to the substrate or dielectric layer. First, the plain language of the claim does not require merely a “layer” having a plurality of vertically oriented semiconductor memory cells, but rather “a stackable add-on layer.” Ex. 1001, 12:29–32. Second, the written description of the ’702 patent strongly suggests that a “stackable add-on layer” is formed separately from the substrate and then stacked on and bonded to the substrate or a dielectric layer above the that in the invention “a plurality of vertically oriented semiconductor memory devices, or cells, may be added to a separately fabricated substrate that includes electrical devices and/or interconnect lines.” Id. at 1:47–50 (emphasis added). Likewise, the specification explains that an SOI layer refers to “a relatively thin, single crystal portion of a semiconductor wafer that can be cleaved and bonded to another previously fabricated wafer, or similar type of substrate.” Id. at 4:47–51. “In this context,” the ’702 patent explains, “the SOI layer may be thought of as an attachment layer, or stackable add-on structure which is suitable for bonding to a semiconductor substrate already containing devices and/or interconnections.” Id. at 4:53– 57. Again, this suggests that a “stackable add-on layer” is separately formed and then bonded to a previously fabricated substrate. Given the structure of the claims and the description of the invention in the written description of the ’702 patent, we preliminarily construe “stackable add-on layer” to be a layer that is formed separately from the substrate and then bonded to the substrate or a dielectric layer above the substrate. We do not understand a “stackable add-on layer” to include memory cells that are formed by sequential deposition on or above a substrate or dielectric layer without being added to a separately formed substrate. slip op. at 8

      “Independent claims 1 and 13 do not specify how the stackable add-on layer is bonded to the dielectric layer. Nor does Petitioner assert that the plain and ordinary meaning of “bonding” refers to “wafer bonding.” Thus, to limit the claims to wafer bonding, Petitioner must identify a clear expression of intent in the ’702 patent to define “bonding” as “wafer bonding,” or a clear disavowal of claim scope demonstrating that non-wafer bonding methods are outside the reach of the claims. See Thorner v. Sony Comp. Entm’t Am. LLC, 669 F.3d 1362, 1365 (Fed. Cir. 2012). Petitioner does not contend that the patentee acted as its own lexicographer by defining “bonding” as “wafer bonding,” a term that does not even appear in the ’702 patent. Id. at 1365. Nor are we directed to any clear disavowal indicating that methods of bonding other than “wafer bonding” are outside the scope of the claims. Id. at 1366. Thus, we decline to construe “bonded” in claims 1 8 Wafer bonding is a method in which semiconductor layers are formed on separate wafers and then bonded together to create a stacked semiconductor structure. Ex. 1003 ¶ 41. that the standards for lexicography and disavowal are “exacting”). As noted by Petitioner, the ’702 patent describes an SOI layer that is wafer bonded to a previously fabricated substrate. Ex. 1001, 4:47–53. Independent claims 1 and 13, however, do not require an SOI layer, and the disclosure of a single embodiment in which wafer bonding is used is not sufficient to import such a limitation into the claims. See Deere & Co. v. Bush Hog, LLC, 703 F.3d 1349, 1354 (Fed. Cir. 2012) (“While claim terms are understood in light of the specification, a claim construction must not import limitations from the specification into the claims.”); Computer Docking Station Corp. v. Dell, Inc., 519 F.3d 1366, 1374 (Fed. Cir. 2008) (“Nonetheless, this court will not countenance the importation of claim limitations from a few specification statements or figures into the claims.”). In summary, we preliminarily construe “stackable add-on layer . . . the first stackable add-on layer is/being bonded” to require a separate layer that is formed apart from the substrate and then subsequently bonded to the substrate or a dielectric layer above the substrate.9 We do not construe independent claims 1 or 13 to require any particular form or method of bonding.10” slip op. at 10

      “The stipulation filed in the Texas litigation mitigates, to an extent, concerns of potentially conflicting decisions and duplicative efforts between the district court and the PTAB.12 Director’s Memo at 7. Similarly, Petitioner’s stipulation in the Oregon litigation (i.e., that it will not pursue an invalidity defense that the claims challenged in this IPR proceeding are invalid based on grounds that were raised or reasonably could have been raised during the IPR) also mitigates concerns of potentially conflicting decisions and duplicative efforts. Patent Owner contends Petitioner’s stipulation falls short of a Sotera stipulation by carving out any circumstance that “otherwise terminate[s] the instituted IPR.” Prelim. Sur-reply 2–3. Patent Owner interprets this carve- on the patent application publication of the Lee patent. Ex. 1007. Because the disclosures of the Lee patent and patent application publication are substantively identical, we consider the stipulation not to pursue any obviousness ground based on Lee to apply with equal force to Lee’s patent application publication. 12 The stipulation in the Texas litigation bars the defendant from pursuing “any obviousness ground that includes” Lee or Watanabe. IPR2023-00900, Exhibit 1031. Here, Petitioner’s grounds 1A–1F challenge claims 13–17 based in whole or in part on Lee, and grounds 2A–2C and 3 challenge claims 1 and 13 based on combinations of references that do not include Lee or Watanabe. Pet. 3. As such, the grounds to be resolved by the PTAB will differ somewhat from those presented in the Texas litigation. written decision, thereby rendering the stipulation an “empty promise” as the district court in the Texas litigation will undoubtedly resolve validity before a final written decision in this case. Id. at 3. We disagree. We do not understand Petitioner’s stipulation to require that a final written decision be issued before the stipulation takes effect. Rather, so long as an inter partes review is instituted, and until such time as the IPR is terminated or vacated, Petitioner will not pursue any invalidity defense before the district court that is “based on grounds that were raised or could have been raised during the IPR.” Ex. 1034. In summary, given the stipulations filed by the petitioners in the Oregon and Texas litigations, it appears that there will be minimal, if any, overlap between the issues raised in the petitions and in the parallel district court proceedings.

Reply Br. 1–2. “[I]nterpreting what is meant by a word in a claim is not to be confused with adding an extraneous limitation appearing in the specification, which is improper.” In re Cruciferous Sprout Litigation, 301 F.3d 1343, 1348 (Fed.

Harris Corp., 156 F.3d 1182, 1186 (Fed.

Advanced Cardiovascular Systems, Inc., 242 F.3d 1337, 1340 (Fed. Cir. 2001). Confining the scope of “capable of imparting solubility” to an unexpressed minimum solubility taken from one of the Specification’s embodiments crosses that line.

The district court stayed the litigation “pending resolution of the IPR proceedings that have been instituted on the patents at issue in this case.” Ex. 2006, 2. Regarding the length of the stay, the district court explicitly ordered the parties not to use continuance of the fact discovery to October 28, 2022 “as grounds for . . . opposing institution of any post-grant proceeding.” Ex. 2007, 2. Regarding when the stay will be lifted, the order merely gives Patent Owner the opportunity to “seek to lift the stay as to any patents that are not instituted for review.” Ex. 2006, 2 (emphasis added). But we decline to speculate whether the district court would grant such a motion directed only to one of the six patents. Among the reasons warranting a stay of the litigation, the district court found “IPR has the potential to streamline issues for trial” and “the resources the parties will need to expend for experts could be significantly impacted by the outcome of any instituted IPR proceedings.” Id. Thus, the litigation is stayed pending the outcome of the six related proceedings, not merely the outcome of this institution decision, and the district court stayed the litigation for the explicit purpose of gaining efficiency and avoiding duplication of efforts by letting this inter partes review proceed to its conclusion first.14 See Prelim.

      “The express language of claim 1 requires no solubility threshold, and dependent claim 10 demonstrates that where a solubility threshold was intended by the inventors of the ’620 patent they knew how to expressly set forth that threshold in the claims.

Thus, the claim language does not support applying a particular solubility threshold in claim 1.
