      “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. Cir. 2016), 815 F.3d at 1363 (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)). This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). slip op. at 8

      “[T]here is no presumption in favor of institution or in favor of finding a reference to be a printed publication under § 42.108(c) or any other authority. . . . [T]he burden is on the petitioner to identify with particularity evidence sufficient to establish a reasonable likelihood that the reference was publicly accessible before the critical date of the challenged patent, and therefore that there is a reasonable likelihood that it qualifies as a printed publication.” slip op. at 20

    • 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

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundReasonable expectation foundInstituted

      “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. Cf. KSR Int’l Co. v. 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

    Rehearing was granted and IPR instituted on claims 1–28 because the petition showed a reasonable likelihood that claim 1 was obvious over Linnarsson, McCloskey, and ordinary skill.

      “III. WHETHER REHEARING IS WARRANTED Petitioner argues that we misconstrued the claims “as requiring one to add tags in a way that can provide a distinction based on a ‘polynucleotide sequence.’” Req. 6 (quoting Dec. 14 (Petitioner’s emphasis)). Petitioner is correct. More specifically, we implicitly construed the claim language reciting “a second tag sequence distinguishing said sample polynucleotide from other sample polynucleotides from said cell,” as requiring said “distinguishing” to be based on the sequences of the sample polynucleotides. See, e.g., Dec. 14 (“[E]ach strand of cDNA that is tagged in Linnarsson is tagged regardless of the polynucleotide sequence of the cDNA or its corresponding mRNA. Thus, Linnarsson’s tags do not distinguish between ‘sample polynucleotides,’ whether cDNA or mRNA, of different sequences.”). Based on that misunderstanding, we erroneously determined that the proposed modification could not achieve the claim language, stating the following: Petitioner’s proposal appears to defeat satisfaction of another portion of claim 1, namely a “second tag sequence distinguishing said sample polynucleotide from other sample polynucleotides from said cell.” Ex. 1001, 30:62–64. For if the second tag is “added to the CDS or TSO after extension,” as opposed to the sample polynucleotide, as Petitioner argues (Pet. 39 (emphasis added)), it would appear that the second tag would be incapable of distinguishing any sample polynucleotide from other sample polynucleotides. Rather, the second tag would be ligated to each and every extension product bearing a CDS or TSO without regard to the sequence of any sample polynucleotide. Dec. 16. We now reconsider whether to institute.” slip op. at 2

      “Cited”). Because we find that the same or substantially the same art was previously presented to the Office, we proceed to part two of the analysis. 2. Advanced Bionics Part Two Patent Owner argues that the Petition “fails to show any error in the Examiner’s application during prosecution of the prior art teachings Petitioner now purports to invoke from . . . McCloskey.” Prelim Resp. 23; see also id. at 24–25 (“Revisiting the same art and arguments already overcome during prosecution is a waste of the Board’s limited resources and would unfairly burden PO.”). However, Petitioner argued that “the Examiner committed major error in Examination by erroneously stating that the prior art fails to teach a dual tagging approach when, in fact, this approach is plainly taught in both McCloskey and McCloskey II.” Pet. 67. The record supports Petitioner’s position, and we agree that the error was material to patentability. See Ex. 1005, 131 (Notice of Allowance). Accordingly, and having considered all of the Becton, Dickinson factors, we do not exercise discretionary denial.” slip op. at 12

    • Obviousness (§103) › Analogous artNot reached

      “the three references is analogous art to the ’013 patent as opposed to each other. Prelim. Resp. 46 (citing Pet. 35; Sanofi-Aventis Deutschland GmbH v. Mylan Pharms. Inc., 66 F.4th 1373, 1374 (Fed. Cir. 2023)). As Sanofi- Aventis holds, a petitioner bears the burden of persuasion to establish that an asserted prior art reference is analogous art to the claimed invention. See Sanofi-Aventis, 66 F.4th at 1377 (“We agree with [the patent owner] that [the petitioner] did not carry its burden to argue that de Gennes is analogous to the [challenged] patent.”); id. (“In evaluating whether a reference is analogous, we have consistently held that a patent challenger must compare the reference to the challenged patent.”); id. at 1378–79 (“We have routinely held that the petitioner has the burden of proving unpatentability.”). However, the Petition should not be denied for failing to state explicitly that the cited prior art references are analogous art to the ’013 patent. Rather, as Sanofi-Aventis further held: “A petitioner is not required to anticipate and raise analogous art arguments in its petition; instead a petitioner can use its reply to ‘respond to arguments raised in the corresponding opposition, patent owner preliminary response, patent owner response, or decision on institution.’” Sanofi-Aventis, 66 F.4th at 1379 (quoting 37 C.F.R. § 42.23).
