    “Petitioner misstates the Decision’s reasoning. As is clear from the previous discussion, we determined that Petitioner’s articulated reasons for combining EP’536 with CN’180 lacked a rational underpinning, not because “EP’536 does not relate to ‘air bags,’” but because the means by which EP’536’s device inflates differs fundamentally from that of CN’180’s device. Dec. 17–18. Petitioner did not acknowledge this critical difference in the Petition, and continues not to do so in its Rehearing Request.” slip op. at 5

    “EP’536 with CN’180 lacked a rational underpinning because EP’536’s inflation mechanism differs fundamentally from CN’180’s inflation mechanism. Dec. 17–18. As we stated, whereas CN’180’s fall-protection belt uses an airbag that requires an external source of pressurized air to inflate, EP’536’s garment does not need an external inflation device because “the gas generating agent 18 in each envelope automatically generates gas and inflates the envelopes in response to rising temperatures.” Id. at 18 (citing Ex. 1004 ¶ 15; Ex. 1005 ¶¶ 5, 19). This difference reflects the fundamentally different purposes of the two devices: CN’180’s device is designed to provide “fall protection” to, e.g., “elderly people,” (Ex. 1005 ¶ 1, 3), whereas EP’536’s device provides “adaptive thermal insulation” for, e.g., garments worn by fire fighters. Ex. 1004 ¶¶ 1–3, 250. Because of the different means by which EP’536’s and CN’180’s devices inflate and the different purposes for doing so, we were not persuaded that one of ordinary skill in the art would have combined the references as Petitioner proposed. Dec. 18. We further noted that the modification would not have improved the reusability of EP’536’s device “by having only one mechanism to recharge,” because EP’536’s “gas generating agent does not need any ‘mechanism to recharge.’” Dec. 18. Instead, we noted EP’536’s teaching that its gas generating agent “automatically recombines or condenses in response to a temperature decrease to return the envelopes, and therefore the garment, to its original thickness, at which point the gas generating agent is ready for subsequent reactivation.” Id. (citing Ex. 1004 ¶¶ 139–141). Finally, we determined that replacing EP’536’s envelopes with CN’180’s airbag “would have made EP’536’s invention unsuitable for its intended purpose: providing a protective garment with ‘adaptive thermal insulation.’” Dec. 19. We stated that “Petitioner does not suggest, and we have found nothing in the record to establish, that CN’180’s airbag would provide this feature.” Id. at 20.” slip op. at 3

    “rationales for combining EP’536 and CN’180. Reh’g Req. 6–7. First, Petitioner asserts that we “improperly rejected Petitioner’s ‘simple substitution’ evidence in view of [the Board’s] incorrect conclusion that EP’536 does not disclose an ‘external source of inflation [EP’536’s dosing aids].’” Id. at 6 (citing Dec. 18–19). This argument is unpersuasive at least because, as we discussed above, EP’536’s dosing aids do not constitute an external source of inflation. Petitioner further argues that we incorrectly evaluated its “obvious to try” rationale because, contrary to our analysis, Petitioner did in fact identify a problem to be solved by its “finite number of solutions”: “simplify[ing] the design and reduc[ing] the number of required inflation mechanisms.” Id. at 6–7. The Petition’s entire “obvious to try” discussion is as follows: [A] POSITA would have found it obvious to try a one-piece airbag 10 with strip-shaped inflation units 12 in the EP’536- CN’180 airbag system because it would have been a selection from a finite number of identified predictable solutions (i.e., using one chamber with connected individual inflation units 12 versus multiple individual envelopes 20). 5 Petitioner also argues that dosing aids are “needed in order to make the disclosed device reusable.” Reh’g Req. 5–6. This is incorrect, as EP’536 conveys that the reusability of the device is a result of the gas generating agent condensing or recombining when temperatures fall. Ex. 1004 ¶¶ 139– 141. Even if it were true, however, it is unclear how it would support Petitioner’s argument. Pet. 16. As is evident, Petitioner did not identify a design need, market pressure, or other problem that would have been addressed by its identified “solutions,” and therefore we were not persuaded by this rationale. Dec. 19. Petitioner’s attempt to cure this deficiency in its Rehearing Request is tardy. We cannot misapprehend or overlook an assertion that Petitioner fails to make in the Petition. It is also insufficient. Petitioner does not provide any evidence of a known design need or market pressure to “simplify [EP’536’s] design” or reduce the number of “required inflation mechanism” it uses.” slip op. at 7

Rep. No. 112–98, pt. 1, at 40 (2011), 2011 U.S.C.C.A.N. 67, 69 (Post grant reviews were meant to be “quick and cost effective alternatives to litigation”)). Because we understand enough of the Petition’s analysis to address each group of asserted grounds on the merits, we decline to exercise our discretion to deny institution based solely on this issue.” slip op. at 11

    “Petitioner submits that a designer of ordinary skill in the art at the time of the invention would have had “a bachelor’s degree in industrial design or an equivalent field, or two years of experience designing cameras or camera housings.” Pet. 11 (citing Bressler Decl. ¶¶ 22–24).

    “In its claim construction section, Petitioner states that the ’435 patent “encompasses a rectangular body with flat faces, a rectangular lens cover extending outward from the front of the body, rectangular buttons/access elements, and rectangles for displays” and “[a]s a whole . . . gives an ordinary designer an overall visual impression of a rectangular design for a camera/camera housing.” Pet. 12 (citing Bressler Decl. ¶¶ 25–26). These descriptions are incredibly general and do not provide an adequate understanding of the overall visual appearance of the claimed design. Moreover, we do not find them helpful in our analysis and, therefore, do not adopt them as a claim construction. Patent Owner does not explicitly address claim construction. See” slip op. at 13

    “Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006. 2. Conclusion: PGR Eligibility For the foregoing reasons, and based on the record before us, we determine that Petitioner has not demonstrated that it is more likely than not that the ’202 patent has, or had, at least one claim having an effective filing date on or after March 16, 2013. Accordingly, we determine that the ’202 patent is entitled to the filing date of the ’634 application (October 18, 2006), and, thus, the ’202 patent is not eligible for post-grant review.” slip op. at 18

  • Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageTerm construed board ownDecided for patent owner

    “Accordingly, the ’202 patent consistently and repeatedly characterizes the invention as incorporating tobacco in some form and ties the stated benefits of the invention to the inclusion of tobacco. Moreover, the Specification is directed to smoking articles containing tobacco, all of the embodiments include tobacco, and “the present invention” is described as a smoking article, where the smoking article includes tobacco. Consequently, we determine that “smoking article” as it is used in the challenged claims is limited to devices that include tobacco. See Mosaic Brands, Inc. v. Ridge Wallet LLC, 55 F.4th 1354, 1361 (Fed. Cir. 2022) (finding claimed “lip” is limited to “extrudable plastic materials” where specification states that “the device of the present invention is constructed of extrudable plastic materials” and “emphasizes the benefits of using extrudable plastics and describes them as benefits of the invention as a whole”); Poly-Am., L.P. v. described in the specification has inwardly extended short seals and every section of the specification indicates the importance of inwardly extended short seals. These two facts provide together a proper reason to limit the claims in this way.”); Phillips v. AWH Corp., 415 F.3d 1303, 1312–1317 (Fed. Cir. 2005) (en banc) (“[T]he specification may reveal an intentional disclaimer, or disavowal, of claim scope by the inventor. In that instance as well, the inventor has dictated the correct claim scope, and the inventor’s intention, as expressed in the specification, is regarded as dispositive.”).” slip op. at 13

    “Petitioner’s argument is dependent on accepting Petitioner’s assertion that the claims include a smoking article that does not contain tobacco, which we have not done. Instead, as set forth above, we construe “smoking article” as being limited to devices that include tobacco. See § II.B.2, supra. Based on our construction of “smoking article” and the evidence of record in this proceeding, we determine that the challenged claims are supported by the specification of the ’202 patent, which is identical to the specification of all of the continuations in the chain leading back to the October 18, 2006 that the specification of the ’202 patent and every patent in its priority chain “have identical specifications”); Prelim. Resp. 13 (noting that Petitioner does not identify other limitations in the challenged claims “allegedly lacking support in the ’202 patent family’s applications dating back to U.S. App. No. 11/550,634, filed on October 18, 2006”). Accordingly, we determine that Petitioner does not demonstrate that it is more likely than not that the challenged claims lack written support in the Specification (and the ’634 application). That is, on this record, it appears that the challenged claims properly claim priority to the ’634 application and, accordingly, have an effective filing date in October 2006.” slip op. at 17

    “Thus, based in part on the “relatively minimal proceedings” in the District Court, and the “[t]he possibility of significant simplification” for the District Court from our claim construction of the term “release logic,” we decline Patent Owner’s invitation to discretionarily deny the petition. Moreover, we need not address Patent Owner’s contentions concerning discretionary denial because, as discussed below, Petitioner has not established a reasonable likelihood of prevailing on the merits in demonstrating unpatentability of any challenged claim of the ’953 patent. See MillerKnoll, Inc. v. Aaron DeJule, IPR2023-01428, Paper 8, 10 (PTAB March 22, 2024).” slip op. at 20

    “We now turn to the merits of Petitioner’s asserted Grounds of unpatentability. Analysis of Claims We focus our analysis on the term “release logic,” which appears in all the challenged claims. As we explained above, we determined that the term “release logic” along with its recited functions should be construed under Section 112 ¶ 6 to cover “corresponding structure, material, or acts described in the specification and equivalents thereof,” that perform the recited functions. Petitioner did not identify how the asserted prior art described those structures or their equivalents. Instead, as discussed above, Petitioner relied on Patent Owner’s preliminary construction in the District Court, which Patent Owner identified in wholly functional terms as a “specific sequence of actions.” Pet. 6 (citing Ex. 1010; Ex. 1002 ¶¶ 52–53); Prelim. CC Reply 1 (citing Ex. 1010, 5). Thus, Petitioner’s analysis fails to address how the prior art meets the limitations set forth in the claims as we have interpreted those claims. Accordingly, we find that Petitioner has failed to meet its burden to establish a reasonable likelihood that it would prevail with respect to at least one of the claims challenged in the petition. Thus we deny institution of an inter partes review. See Samsung Elecs. Am., Inc. v. Cobblestone Wireless, LLC, IPR2024-00319, Paper 16, slip op. 16–23 (PTAB Jun. 24, 2024) (holding that because Petitioner’s obviousness showing was based on an incorrect claim construction, Petitioner did not demonstrate a reasonable likelihood that a claim limitation was disclosed by, or would have been obvious over, the cited reference).” slip op. at 49

    “be persuasive, we conclude that an ordinarily skilled artisan would not have understood “release logic” to refer to, or to have a definite meaning as the name for structure. Accordingly, we find that any presumption that the claims at issue do not invoke § 112, ¶ 6 is overcome, and we conclude that “release logic” introduces claim language that is properly interpreted under § 112, ¶ 6. Dr. Hull’s testimony in the District Court appears to address only the embodiment disclosed in Figures 9–11 of the ’953 patent. He did not opine on the other embodiments disclosed in the patent, such as the embodiment in Figures 22–24 disclosing electronic third-quadrant release-logic binding system 2204. However, his testimony that the words of the claim would not be understood by an ordinarily skilled artisan to have definite meaning as the name for structure remains persuasive.” slip op. at 48

    “sophistication of the technology; and (5) educational level of active workers in the field.” Id. ¶ 30. Dr. Hull fails to state whether these factors were relied upon in forming his opinion, and if so, he also fails to state the underlying facts or data relating to these factors on which the opinion is based. There is no evidence to support why an “advanced degree” in mechanical engineering and five years of relevant experience is required. His opinion is supported only by his statement that he is “familiar with the technology at issue here and the state of the art at the time the application leading to the ’953 patent was filed.” Ex. 1002 ¶ 31. Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight. 37 C.F.R. § 42.65(a). Here, based on Dr. Hull’s extensive experience, we give his testimony some, but little, weight. Patent Owner states that “for purposes of this Preliminary Response only, VSD does not now dispute the definition of the POSITA as set forth by Dr. Hull.” Prelim. Resp. 7. We note that Patent Owner’s position is based on Dr. Hull’s full testimony, not the excerpt asserted by Petitioner. Accordingly, for purposes of this Decision, and based on the limited record before us, we determine, based on Dr. Hull’s testimony, the cited prior art, and Patent Owner’s qualified agreement with Dr. Hull’s testimony, that a person of ordinary skill in the relevant technology would have had an advanced degree in mechanical engineering or a related discipline and five years of experience in either ski binding design, manufacture, or testing; research concerning ski bindings and related equipment; or the development of standards concerning ski bindings or related equipment. This level of skill is approximate, and more experience would compensate for less formal education, and vice versa.” slip op. at 25
