      “review. 35 U.S.C. § 314(b) (2018); 37 C.F.R. § 42.4(a) (2019). An inter partes review may not be instituted “unless . . . the information presented in 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.” 35 U.S.C. § 314(a). Upon consideration of the Petition, the Preliminary Response, and the evidence of record, we conclude that Petitioner has not established a reasonable likelihood of prevailing on its assertion that at least one challenged claim is unpatentable based on the grounds advanced here. Accordingly, we deny institution of inter partes review of claims 1–20 of the ’967 patent.” slip op. at 2

Petitioner adopts the following definition of a person of ordinarily skill in the art (hereafter, sometimes “POSITA”) of the ’967 patent proposed by Patent Owner in the Avery Dennison litigation: [A]t least a bachelor’s degree in electrical engineering, computer science, or computer engineering, or a related discipline, and at least five years of experience which would consist of, A, designing, developing, evaluating and/or using RFID or other AIDC [automatic identification and data capture] technologies in inventory management, unique object identification, and/or security; or B, studying and conducting research related to RFID technologies and using RFID and other AIDC technologies in inventory management, unique object identification, and/or security. Pet. 6 (citing Ex. 1030, 707:3–13). Patent Owner does not offer a definition of an ordinarily skilled artisan of the ’967 patent at this time. See generally Prelim. Resp. Based on the information presented, we find that the asserted prior art itself is sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself can reflect the appropriate level of ordinary skill in the art). To the extent a more precise definition is required, we apply Petitioner’s unopposed proposed definition for purposes of determining whether to institute review because it is consistent with the disclosures of the asserted prior art references and the problems addressed in the ’967 patent.” slip op. at 17

      “Petitioner proposes the following claim constructions: “an allocated block of serial numbers” as “a pre-authorized range of binary serial numbers” and “uniquely corresponding” as the “term’s plain and ordinary meaning, consistent with the articulation of the plain and ordinary meaning” in the Avery Dennison litigation. Pet. 8–12. As to the remaining claim terms, Petitioner applies the district court’s constructions in the Avery Dennison litigation. Id. at 12 (citing Ex. 1028). Patent Owner applies the following constructions that were entered during in the Avery Dennison litigation: “object class information space” as “data field within the memory of the RFID integrated circuit chip for information identifying the class of an object, such as a company prefix, item reference code, partition value, and/or filter value,” “unique serial number space” as “data field within the memory of the RFID integrated circuit for information identifying a unique serial number,” “being assigned a limited number of most significant bits” as “includes a limited, predefined sequence at the leading end,” “remaining bits of lesser significance” as “the remaining lower order bits at the trailing end,” “is encoded with one serial number instance” as “has stored within it one serial number instance,” “an allocated block of serial numbers” as “a pre-authorized range of serial numbers,” and “uniquely corresponding” as its plain and ordinary meaning. Prelim. Resp. 32. For purposes of resolving whether to institute trial, we adopt and apply the interpretations stated in the district court’s claim construction order and applied by the Federal Circuit on appeal, Ex. 1028.11 See 55 F.4th 900, 908–909, 912–913 (Fed.

See Pet. 34–39; Ex. 1005 ¶¶ 167–176. However, on this record, Petitioner has not sufficiently shown that the POSITA, having read IBM200 and Kuhno, would have been led to create a serial number space in which the limited number of “most significant bits” uniquely corresponds to those bits assigned to an allocated block of serial numbers, as recited in limitation [f].” slip op. at 25

      “However, neither Petitioner nor Dr. Jansky provide specific data on the record before us showing the actual measured homozygosity of either of the inbred lines, US-W 5309 and US-W 5315. And Phumichai experimentally demonstrates that Dr. Jansky’s assumption that theoretical heterozygosity reduction of 50% per generation is not necessarily accurate, stating the “observed average percentage of reduction of heterozygosity per generation (38.4% or 38.5%) was lower than the theoretically expected value of 50%.” Ex. 1005, 982. Indeed, Phumichai disclosed that the “SOPH [Section-based observed percentage of heterozygosity] decreased steadily from the original 100% in 99H2–1 (S0) to the family means of 62.4% in 3H2 (S1), 37.9% in 3H3 (S2).” Id. at 981. That is, Phumichai experimentally shows that in an S2 generation of a potato line, the heterozygosity was 37.9%, resulting in homozygosity of about 62.1%, below the 75% theoretically expected and the 75% required by claim 1 of the ’841 patent. Therefore, the evidence of record does not show that the S2 generation of potato lines in Jong necessarily satisfies the homozygosity recitation in claim 1 of the ’841 patent, and so cannot establish on the record before us that Jong inherently teaches this limitation.” slip op. at 15

      “Petitioner’s position further relies on the declaration testimony of Dr. Baker who states a POSITA “would read Knoth to include independent first and second PLLs within clock ratio controllers 106a and 106n, respectively, receiving the first and second clock signals (the timing pulses generated by oscillators 219a and 219n) that are independent from each other.” Pet. 28– 29 (quoting Ex. 1003 ¶ 132, citing id. ¶¶ 111, 131). We do not credit Dr. Baker’s testimony on this point because it lacks sufficient explanation and is inconsistent with the disclosure of Knoth as detailed above. 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight”); Xerox Corp. v. Bytemark, Inc., IPR2022-00624, Paper 9 at 15 (PTAB Aug. 24, 2022) (precedential). Dr. Baker’s testimony appears premised on the assertion that each clock ratio controller 106a-n operate independently from each other. Ex. 1003 ¶ 130. However, Dr. Baker does not explain why independently operating clock ratio controllers teach or suggest that each clock ratio controller would receive an independent input clock signal.” slip op. at 20

      “determine that Petitioner has not sufficiently shown that Knoth or Allarey disclose two independent clock signals. First, we are not persuaded that Petitioner has shown sufficiently that Knoth includes a PLL in each clock ratio controller. Instead, we agree with Patent Owner that Knoth discloses clock ratio controllers 106a-n coupled to a single PLL 202 where PLL 202 receives a single clock input from oscillator 119. Prelim. Resp. 6–8 (citing Ex. 1005 ¶¶ 22, 41, Fig. 2A). Figure 2A, reproduced above, clearly delineates clock ratio controller 106 within a dotted line separate from PLL 202 and oscillator 119. Further, as noted by Patent Owner, Knoth explicitly describes a plurality of clock ratio controllers and processor cores designated as a-n, but only describes a single PLL 202 and oscillator 119. Id. at 8, 11 (citing Ex. 1005 ¶¶ 22, 41–42). Because Petitioner has not shown that Knoth discloses two PLLs, Petitioner fails to show a first and second PLL with respective first and second clock signals as inputs where the first clock signal is independent from the second clock signal.” slip op. at 19

Here, however, as Patent Owner observes (Prelim. Resp. 10), 8 Patent Owner does not present arguments or evidence of secondary considerations in its Preliminary Response. Therefore, secondary considerations do not constitute part of our analysis herein. Petitioner has provided no assessment as to the level of ordinary skill to be considered in evaluating the grounds of obviousness that are advanced by Petitioner.

      “A petition must identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim.” 35 U.S.C. § 312(a)(3) Here, Petitioner merely provides general assertions about multiple references, without clearly identifying how, or why a POSITA would have been motivated, to modify the processes disclosed in those references to arrive at the claimed invention. Thus, the Petition does not state with particularity that Saxler’s particular technique for etching is to be used instead of Beach’s etching step when substituting Beach’s self-aligned process for Saxler’s two mask process. Nor does the Petitioner provide a sufficient reason, absent hindsight, why a POSITA would have been motivated to combine the references to result in a process that forms Saxler’s Modified Figure 1A.

Contrary to Petitioner’s assertions in its Reply and at the hearing, the Petition makes no argument that a POSITA would have removed the recess from Saxler Figure 1A to realize the benefits of an enhancement mode transistor. See Reply 4–5; Pet. 24–68.

Dec. 11–16 (citing Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017); Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). We invited the parties to address this limitation further during the course of this trial, but neither party provided additional evidence or argument regarding the “side surfaces” limitation. Inst. Dec. 16; see generally PO Resp.; Reply; Sur-reply. Accordingly, we maintain our determination from the Institution Decision that we do not need to construe the “side surfaces” limitation. Inst.

      “This evidence, particularly the language in the ’335 patent itself, undermines Patent Owner’s argument that “[t]he process for forming gate ledges using separate masks instead of the self-aligned process disclosed in the ’335 patent cannot produce ledges that are ‘substantially symmetric.’” PO Resp. 39 (emphasis added); see also PO Resp. 42–43 (arguing that a gate structure with ledges having substantially equal widths is “not achievable” without using a single photo-mask process). We have considered the evidence presented by Patent Owner and Dr. Schubert in support of Patent Owner’s arguments. PO Resp. 38–43; Ex. 2005 ¶¶ 49–51. We, however, are unable to discern sufficient evidence supporting a conclusion that using separate masks cannot produce ledges that are substantially symmetric, particularly when the ’335 patent suggests otherwise. See Ex. 1001, 4:60– 63 (referring only to the “possibility of misalignment”). Even if, as Patent Owner and Dr. Schubert contend, misalignment “naturally” occurs when using a two-mask process, that does not foreclose the possibility that the” slip op. at 18

      “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed.

    • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner

      “May” expresses a possibility. The Specification reflects this interpretation of “may” when it states that “[i]n one embodiment, the organic material is not lyotropic. Thus, the organic material may not be a phospholipid.” Ex. 1001, 8:27–28 (emphasis added). One of ordinary skill would understand from this that the organic material “may not be” a phospholipid if the organic material is not lyotropic. It follows that if the organic material is lyotropic, then the organic material may be a phospholipid. Reading the statement “[t]he organic material may not be . . . a phospholipid” (id. at 8:59–63) in light of the earlier stated possibility that the organic material may be a phospholipid if the organic material is lyotropic, one of ordinary skill in the art would interpret “may not be” as excluding phospholipids under some conditions, not under all conditions. Taking the Specification’s discussion about phospholipids as exemplifying the permissive nature of the word “may,” we are unpersuaded that in stating that “[t]he organic material may not be [PMMA], a polyvinylidene difluoride-containing polymer, such as [PVDF] or PVDF- TrFE-CTFE, or a phospholipid, such as [DHPE]’” (Ex. 1001, 8:59–63), the specification “contains a clear and unmistakable disavowal of the compounds PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE” and “disclaims the listed compounds” from the “organic material” of the claims under all conditions, as Patent Owner argues. Prelim. Resp. 6–7. Moreover, the claims themselves limit the “organic material” only to the extent that it is “barocaloric cooling or heating agent” and can perform in the manner claimed. See Ex. 1001, claim 1, supra. As broadly worded, the claims do not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE per se from the group of organic materials employed by the claimed method. Adopting Patent Owner’s construction would impermissibly import a limitation (i.e., not exclude PMMA, PVDF, PVDF-TrFE-CTFE, and DHPE) into the claims. For the reasons stated, at this stage of the proceeding, we agree with Petitioner’s broad construction of “organic material.” We do not adopt Patent Owner’s proposed construction whereby PMMA, PVDF, PVDF- TrFE-CTFE, and DHPE are excluded from the scope of the claim term “organic material.” The parties are invited to address this issue further during trial, if desired. slip op. at 11

      “Petitioner shows that (a) Mañosa (i.e., inorganic compounds such as Ni-Mn-In, Gd5Si2Ge2, and La-Fe-Co-Si) and (b) Patel (i.e., PVDF-TrFE- CTFE) teach materials exhibiting inverse BCEs. Pet. 59 (citing, inter alia, Ex. 1007, pages 4–8; Ex. 1009, 1, 4–5; Ex. 1004 ¶ 108). In our view, at this stage, Petitioner sufficiently shows (via the five reasons listed supra) why it would have been obvious to one of ordinary skill in the art to substitute the barocaloric cooling or heating agent of Patel for that taught in Mañosa, thereby reaching the claimed method with a reasonable expectation of success.

Teleflex Inc., 550 U.S. 398, 416 (U.S., 2007) (“The Court recognized that when a patent claims a structure already known in the prior art that is altered by the mere substitution of one element for another known in the field, the combination must do more than yield a predictable result.”)” slip op. at 32
