“Petitioner contends that one of ordinary skill in the art “would have had at least a Bachelor’s degree in electrical engineering, material science, chemical engineering, or an equivalent field, as well as at least 2 to 3 years of academic or industry experience in the recycling or processing of lithiumion batteries. Additional formal education focusing on processing of lithium batteries may substitute for practical experience and additional practical experience can substitute for less education.” Pet. 10–11. Patent Owner does not contest this definition of a person of skill in the art. See Prelim. Resp. 11. For purposes of this Decision, we adopt Petitioner’s assessment of the level of ordinary skill in the art, as, on the present record, it appears consistent with the ’463 patent and the asserted prior art.

“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. Weighing this evidence all together, we find that Petitioner has failed to show that it is more likely than not that Tomioka’s teaches the claimed comminution under Petitioner’s first theory.” slip op. at 15

“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. Thus, we find that Petitioner has failed to show that it is more likely than not that Tomioka accounts for the claimed “comminuting.”” slip op. at 15

“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.

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).

“one claim is unpatentable and that one of Petitioner’s challenges presents strong merits—are sufficient to show that the likelihood of Petitioner’s success at trial falls within the uncertain bounds of “highly likely.”5 Accordingly, we determine that the Petition “presents compelling evidence of unpatentability” as that phrase is defined in the Guidance Memo and the OpenSky decision.

Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–697 (Fed. Cir. 1983) (citing Orthopedic Equip. Co. v. All Orthopedic Appliances, Inc., 707 F.2d 1376, 1381–82 (Fed. Cir. 1983)). Not all such factors may be present in every case, and one or more of these or other factors may predominate in a particular case. Id. Petitioner argues a person of ordinary skill in the art at the time of the invention “would possess at least a B.S. in chemistry or chemical or mechanical engineering and would have at least one year of experience working on control of automotive evaporative emissions,” and “would also understand the chemistry and physics associated with the phenomena of fuel vapor adsorption, desorption, and diffusion.” Pet. 28 (citing Ex. 1003 ¶ 17). Patent Owner does not dispute the level of ordinary skill in the art. We adopt Petitioner’s definition of the level of ordinary skill in the art because it is consistent with the ’553 patent and the asserted prior art.” slip op. at 11
- Expert testimonyPatent owner expert creditedDecided for patent owner
“Patent Owner and Dr. Rockstraw present peer-reviewed scientific literature demonstrating that gravimetric and volumetric measurement techniques were known to measure equivalent adsorption capacities and were viewed as compatible with each other. See Ex. 2022 ¶¶ 95–107 (addressing Anson7 (Ex. 2007), Belmabkhout8 (Ex. 1021), Zielinski9 (Ex. 2069)). For example, Belmabkhout reported similar results between measurements by gravimetric and volumetric instruments, except at very high pressures. Ex. 1021, 856–57. Zielinski reported “excellent agreement” between volumetric and gravimetric adsorption capacity measurements (Ex. 2069, 5–6); Dr. Zielinski (who oversaw the testing reported by Intertek 7 Anson, A., et al., “Hydrogen adsorption on a single-walled carbon nanotube material: a comparative study of three different adsorption techniques,” Nanotechnology 15 (2004), 1503. 8 Belmabkhout, Y., et al., “High-pressure adsorption measurements. A comparative study of the volumetric and gravimetric methods,” Measurement Science and Technology 15 (2004) 848. 9 Zielinski, J. et al., “High pressure sorption isotherms via differential pressure measurements,” Adsorption 13 (2007), 1–7. in Ex. 1020) also testified that he would expect capacity measurements for either a gravimetric or volumetric technique to yield the same results, or be “superimposable” under ideal conditions, because they represent “the same experimental measured quantities.” Ex. 2026, 52:11–53:7, 54:13–22, 69:12– 70:3, 139:8–19. Petitioner’s argument that these papers are not relevant because they do not address measurements on the adsorption capacity of n-butane (see Pet. Reply 26) is not persuasive, because Petitioner does not direct us to sufficient evidence showing a reason why measurements of n-butane’s adsorption capacity would have been subject to different measurement inconsistencies. Further, Petitioner’s argument about a 3% deviation in results between the measurement techniques reported in Anson and Belmabkhout is not persuasive because the papers’ conclusions suggest a person of ordinary skill in the art would not have seen such a deviation as significant (e.g., Ex. 1021, 849: “we have not observed important discrepancies” between gravimetric and volumetric measurements). Dr. Rockstraw also testifies as to numerous additional texts and standards that confirm persons of ordinary skill in the art understood that gravimetric and volumetric measurement techniques would provide consistent results when proper experimental protocols are followed and the instruments’ accuracy and precision are taken into consideration. See Ex. 2022 ¶¶ 88–91, 119–127. This evidence is essentially unrebutted by Petitioner. We find that the evidence submitted by Patent Owner as to the gravimetric and volumetric measurement techniques demonstrates that they were well established in the art as comparable methods of measuring adsorption capacity, and accordingly, not a basis for determining claim” slip op. at 16

“Exhibit 2027. Paper 57 (“Pet. Mot.”). We do not discuss or cite Exhibit 2080 or paragraph 39 of Exhibit 2027 in this Decision, and consideration of them played no part in our determinations set forth herein. Because their presence in the record would not affect our analysis in this Decision, we dismiss as moot Petitioner’s motion with respect to these exhibits. B. Patent Owner’s Motion to Exclude Patent Owner filed a motion to exclude Exhibits 1015–1016, 1023– 1025, 1032, 1038–1039, 1042 (certain paragraphs), 1044, 1046–1049, and 1052–1054. Paper 56 (“PO Mot.”). Patent Owner groups these exhibits into four categories, which we apply in discussing the motion below. 1. Patent Owner moves to exclude Exhibits 1015 and 1046 as “irrelevant determinations from other adjudicative bodies regarding different patents.” PO Mot. 1. We do not discuss or cite these exhibits in this Decision, and have not considered them in reaching our decision herein. Because the presence of these exhibits in the record would not affect our analysis in this Decision, we dismiss as moot Patent Owner’s motion with respect to these exhibits. 2.
