The disclosure need only reasonably convey to a POSA that the inventor had possession of the subject matter in question, even if every nuance of the claims is not explicitly described in the specification.

Analysis of Claims 1–18 Schuster is available as prior art if the ’993 patent is only entitled to its January 27, 2014, filing date and not entitled to claim priority to earlier filing dates of the parent applications. On its face, the ’993 patent claims priority to a number of earlier parent applications, including Application No. 12/786,904 (the ’904 Application) filed May 25, 2010, and the Application code 63. Petitioner contends that the ’993 patent is not entitled to claim priority to the filing date of the earlier parent applications, and, thus, Schuster, a parent application of the ’993 patent, is available as prior art.15 Pet. 91–92. Petitioner alleges that the earlier parent applications, specifically Application No. 12/786,904 (the ’904 Application), do not provide written description support for the ’993 patent’s claim term “water flow regulator.” According to Petitioner, “water flow regulator” encompasses both adjustable devices for restricting the flow of water (i.e., valves) and fixed devices for restricting the flow of water (i.e., restrictors). Pet. 15. Petitioner contends that the ’904 Application does not provide support for water flow restrictors and, thus, does not provide support for the broader claim term water flow regulators. Id. at 14–15, 91–92. Petitioner argues that only adjustable water flow devices (i.e., valves) are supported by the ’904 Application. Id.

To be entitled to claim the benefit of an earlier filing date under 35 U.S.C. § 120 each application in the priority chain must comply with the written description requirement of 35 U.S.C. § 112(a). See Hollmer v. 14 The parties do not dispute that the ’993 patent and the earlier parent applications, including the ’904 Application and the ’606 Application, have the same pertinent portions of their specifications.

      “distinct from “comminute[ion],” Petitioner offers only the testimony of its expert, Mr. Juzkow, who equates Tomioka’s “cutting” with “comminute[ion].” See Ex. 1003 ¶ 121. However, Mr. Juzkow provides insufficient reasoning to support his conclusion, particularly given the intrinsic and extrinsic evidence discussed above. In contrast, Patent Owner’s expert, Mr. Dantam, provides extensive reasoning, supported by citations to other evidence, to support his conclusion that Tomioka’s “dismantling” is not the claimed “comminution.” Thus, we give more weight to Mr. Dantam’s testimony than Mr. Juzkow’s testimony.

      “obvious. Pet. 34–35. However, we agree with Patent Owner that Petitioner has also failed to show that it is more likely than not that Tomioka renders this limitation obvious. See Prelim. Resp. 28–31. To begin with, Petitioner’s contentions lack sufficient reasoning explaining why a person of ordinary skill would have modified Tomioka in the manner proposed. “[R]ejections on obviousness grounds cannot be sustained by mere conclusory statements; instead, there must be some articulated reasoning with some rational underpinning to support the legal conclusion of obviousness.” In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006). Petitioner merely asserts that a person of ordinary skill in the art could use the roller system in place of the dismantling disclosed for the embodiments in Figures 19 and 20. On this record, we find this bare contention insufficient. actual disclosure of Tomioka. The rollers in Tomioka are used to separate the “battery body” from the “resin package enclosing the battery body,” and Tomioka specifically discloses that this technique is designed to “avoid damaging the battery body.” Ex. 1005 ¶¶ 25, 26, 29; Ex. 2011 ¶¶ 72–73. Thus, there is a significant difference between what Tomioka teaches and what Petitioner proposes to use the roller system to do. In addition, as Patent Owner points out, Tomioka specifically discloses there are risks associated with mechanically crushing battery packs, such as “risk of sparking due to residual voltage if the battery units are damaged in the process.” Ex. 1005 ¶ 5. Although we do not agree with Patent Owner that this amounts to a “teaching away,” see In re Gurley, 27 F.3d 551, 553 (Fed. Cir. 1994), we do believe that this teaching suggests a trade off that should be weighed in determining whether to make the modification, see Medichem S.A. v. Rolabo S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). However, Petitioner has failed to account adequately, if at all, for this trade off.

      “B. Claim Interpretation We interpret each challenged claim using the same claim construction standard that would be used to construe the claim in a civil action under 35 U.S.C. 282(b), including construing the claim in accordance with the ordinary and customary meaning of such claim as understood by one of ordinary skill in the art and the prosecution history pertaining to the patent. 37 C.F.R. § 42.200(b). Petitioner states that, “for purposes of [its] Petition, the Board need not construe any claim terms to resolve the parties’ disputes, and the claims should be given their ordinary and customary meaning.” Pet. 20. Patent Owner agrees that “[n]o constructions are necessary” to decide the issues disputed by the parties. Prelim. Resp. 2–3.

In particular, the parties are encouraged to address (1) how the collateral estoppel requirement that the issue be “identical to one decided in the first action” applies in the context of an asserted ground under 35 U.S.C. § 101, and (2) the parties’ apparent disagreement as to whether collateral estoppel may be applied in such circumstances on a “limitation-by-limitation basis.” See Pet. 72, 75 (quoting Google LLC v.

      “Exhibits 1013 and 1014 are also not admissible as expert testimony because Mr. Wirén is not “qualified as an expert by knowledge, skill, experience, training, or education.” Fed. R. Evid. 703. “To offer expert testimony from the perspective of a skilled artisan in a patent case—like for claim construction, validity, or infringement—a witness must at least have ordinary skill in the art. Without that skill, the witness’ opinions are neither relevant nor reliable.” Kyocera Senco Indus. Tools Inc. v. Int’l Trade Comm’n, 22 F.4th 1369, 1376–77 (Fed. Cir. 2022). Mr. Wirén does not meet our definition of a person of ordinary skill in the art. See Section II.B, supra. That definition is based on the undisputed testimony of Messrs. Zotterman and Klass. Ex. 1003 ¶ 24; Ex. 2003 ¶ 26. Although Mr. Wirén has a Master’s of Science in chemical engineering, he lacks any experience or specialization in paperboard manufacturing.

We therefore agree with Patent Owner that Exhibits 1013 and 1014 are the testimony of Mr. Wirén and should be excluded from evidence because Mr. Wirén is not a person of ordinary skill in the relevant art.

      “A claim construction that excludes a particular element is viewed as a “negative limitation.” Ethicon LLC v. Intuitive Surgical, Inc., 847 Fed. App’x 901, 907 (Fed. Cir. Mar. 15, 2021). “[S]uch exclusions must find support either in ‘the words of the claim’ or through an ‘express disclaimer or independent lexicography in the written description that would justify adding that negative limitation.’” Id. (citing Omega Eng’g, Inc. v. Raytek Corp., 334 F.3d 1314, 1323 (Fed. Cir. 2003); CCS Fitness, Inc. v. Brunswick Corp., 288 F.3d 1359, 1366–67 (Fed.

(citing Thorner, 669 F.3d at 1365). Similarly, disclaimer or disavowal requires that the specification or prosecution history demonstrate that the invention does not include a particular feature. Id. Here, we find no claim language, lexicography, or disclaimer in the ’142 Patent or its file history that would support defining a “hot-hard calender” as requiring that only one of the two rollers be heated to an elevated temperature.” slip op. at 12

      “a contact surface of said thermo-roller is heated to an elevated temperature of at least 250°F.” Petitioner shows persuasively that the temperature limitation is taught by the combination of Fugitt and Papermaking. Pet. 32–34. Fugitt discloses that “[t]he rolls of the calender may be steam heated.” Ex. 1004 ¶ 26. In a section titled “Heated Rolls,” Papermaking discloses that “Steam can be used up to 170°C [338°F] surface temperature.” Ex. 1010, 95, 98. Petitioner is thus correct that, “[w]hile Fugitt teaches that a hot calender may be steam heated, Papermaking clarifies that one of ordinary skill in the art would understand that steam heated thermo-rollers may reach up to 338°F.” Pet. 36. Based on these disclosures, we are persuaded by Mr. Zotterman’s testimony that it would have been “obvious to heat the thermo-roller of Fugitt to at least 250°F.” Ex. 1003 ¶ 159. combine Fugitt and Papermaking because of Papermaking’s status as a “trusted handbook[],” because both references disclose a method of manufacturing a paperboard structure with hot calendering,” and “because of the known advantages of heated rollers.” Pet. 36–37; Ex. 1003 ¶¶ 157, 159, 162. Petitioner’s contention is supported by Papermaking’s disclosures that, for cartonboard, “[p]recalendering is used before the coater to reduce roughness and porosity” and “[h]igh thermo roll temperatures (in some cases over 200°C) result in bulk savings because of the temperature gradient.” Ex. 1005, 80–82; see also Pet. 38; Ex. 1003 ¶ 164 (citing these disclosures). Papermaking’s disclosed range of “up to 170°C [338°F]” for steam- heated rolls (Ex. 1010, 98), overlaps the claimed range of “at least 250°F.” Patent Owner agrees. Tr. 27:11–13. “If the relevant comparison between a disputed claim limitation and the prior art pertains to a range of overlapping values, ‘. . . even a slight overlap in range establishes a prima facie case of obviousness.’” Genentech, Inc. v. Hospira, Inc., 946 F.3d 1333, 1341 (Fed. Cir. 2020) (citing In re Peterson, 315 F.3d 1325, 1329 (Fed.

      “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.

      “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.
