“referring to the same direction as the separation of the “upper chamber” and “lower chamber” (vertically in both Figure 6 of the challenged patent and Figure 1 of Goubet), we turn back now to Petitioner’s discussion of clause 1F, which includes the limitation at issue. There, Petitioner does not discuss why the “diffusion assembly” is allegedly “disposed between” the “upper chamber” and “lower chamber,” but instead, Petitioner discusses why a component of the “diffusion assembly”—the “atomizer assembly”—is allegedly “disposed between” the “upper chamber” and “lower chamber”: Pet. 39. In the end, we need not assess whether the “atomizer assembly” identified by Petitioner is “disposed between” the “upper chamber” and “lower chamber” under the proper construction of that term (which, again, we need not and do not determine here) because the “disposed between” limitation does not involve the “atomizer assembly.” Instead, we find that, by failing to address why the identified “diffusion assembly” is “disposed between” the identified “upper chamber” and “lower chamber,” Petitioner has failed to provide persuasive evidence that Goubet discloses or suggests the “disposed between” limitation. Pet. 38–39 (discussing the claim language “said diffusion assembly is disposed between said upper chamber and said lower chamber” but only discussing the location of the “atomizer assembly”); see 35 U.S.C. § 316(e) (“In an inter partes review . . . , the petitioner shall have the burden of proving a proposition of unpatentability by a preponderance of the evidence.”). For the reasons above, we find, based on the complete record, that Petitioner has not shown by a preponderance of the evidence that Goubet discloses or suggests the “disposed between” limitation.” slip op. at 22

“Network LLC, 929 F.3d 1350, 1357 (Fed. Cir. 2019). At first glance, the language of the limitation at issue—which, again, recites “the compressed air and the operative fluid mix together in said mixing chamber to form the fluid dispersion”—would seem to require the “fluid dispersion” (under the stipulated construction) to be fully formed in the “mixing chamber.” In other words, the language of the limitation alone would seem to support Patent Owner’s proposed construction for the “form the fluid dispersion” limitation. But the claim construction analysis does not end with consideration of the claim language alone. Next, we turn to the Specification. The Federal Circuit has said that the specification “is the single best guide to the meaning of a disputed term.” Phillips, 415 F.3d at 1315 (quoting Vitronics Corp. v. Conceptronic, Inc., 90 F.3d 1576, 1582 (Fed. Cir. 1996)). Here, the discussion in the Specification of precisely the same language as in the limitation at issue strongly supports that “to form a fluid dispersion” in the limitation at issue requires only initial mixing of the compressed air and operative fluid in the mixing chamber, with further “formation” of the ”fluid dispersion” occurring downstream of the mixing chamber: More importantly, the “predetermined amount” of compressed air and the “preselected amount” of the operable fluid are initially mixed together in the mixing chamber 226 to form a fluid dispersion. The diffusion chamber 112" is further structured to facilitate the formation of a plurality of substantially uniform droplets, as defined hereinabove, in the fluid dispersion prior to discharge from the diffusion chamber 112" through discharge port 132. Ex. 1001, 10:62–11:2 (emphasis added) (discussing Figure 6), quoted, in part, at Pet. Reply 6–710; see also Ex. 1001, 5:64–6:4 (same language, except without double primes, in a discussion of Figures 1 and 2). To be sure, certain passages in the Specification could be read to indicate that a “fluid dispersion” must be fully formed in the “mixing chamber.” See, e.g., Ex. 1001, 6:11–12 (“More in particular, the suppression chamber 232 receives the fluid dispersion from the mixing chamber 226.”); see also id. at 7:22–33, 11:39–52 (both implying that a “fluid dispersion” is formed in the mixing chamber).

“To satisfy its burden of proving obviousness, a petitioner cannot employ mere conclusory statements. The petitioner must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed. Cir. 2016); TriVascular, Inc. v. Samuels, 812 F.3d 1056, 1066 (Fed. Cir. 2016) (“Although the KSR test is flexible, the Board ‘must still be careful not to allow hindsight reconstruction of references . . . without any explanation as to how or why the references would be combined to produce the claimed invention.’”) (citation omitted). Based on the complete record, we agree with Patent Owner that “Petitioner’s asserted motivation boils down to the conclusory statement that given Goubet and Kaiser, ‘it was well known in the field at the time of the invention that droplets of greater uniformity result in uniform droplet evaporation.’” PO Resp. 31 (quoting Pet. 59). We agree with Patent Owner that Petitioner’s discussion of the alleged reasons to combine (Pet. 59) is insufficient to support the proposed combination here. See Magnum Oil, 829 F.3d at 1380. Specifically, we are not persuaded that Kaiser’s teachings—which relate to combustion (Ex. 1014 at 43)—would have led one of ordinary skill in the art to the proposed modifications, which would allegedly “improve the smoothness (i.e., less harsh) of the aroma generated as the oil droplets evaporate in the surrounding airspace.” See Pet. 59 (emphasis added); White Pet. Decl. ¶ 251 (same); see PO Resp. 32 (“Rather, Dr. White merely describes the ability to achieve the effect as in the claimed patent, not why a [person of ordinary skill in the art] would look to the field of electrospray injection and combustion in mesoscale power-generation systems, using high-voltage electric fields to generate charged fuel droplets for controlled combustion in catalytic micro-combustors when considering atomization for scents.”). For these reasons, we determine, in light of the complete record, that Petitioner has not shown by a preponderance of the evidence that one of ordinary skill in the art at the time of the invention would have had reason to combine Goubet and Kaiser, as proposed. slip op. at 32

“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

“For the foregoing reasons, the underlying premise of Serendia’s arguments here and in the ’386 IPR remains substantially the same.

“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 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.
