“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

“the knowledge of one of ordinary skill in the art relating to charge-trap memory devices demonstrates fast charge removal. See Pet. 36, 81–82. And although Petitioner cites its declarant, Dr. Liu, for the proposition that “Seo discloses, and would have been understood to disclose, performing its read operation on charge-trap memories, which removes fast charges,” Dr. Liu does not cite objective evidence to support this assertion, aside from the ’342 patent itself. Id. at 36 (citing Ex. 1003 ¶ 136). Moreover, Dr. Liu’s testimony simply circles back to logic similar to that relied on with respect to the inherency theory, namely that, given certain similarities between Seo and the ’342 patent, Seo removes fast charges because the ’342 patent teaches removing fast charges, even though Seo does not explicitly teach doing so. See Ex. 1003 ¶ 136 (“[A] POSITA would have immediately understood from reading Seo that Seo is disclosing its read operation as applicable to Flash memories, including Flash charge-trap memories. And as the ’342 states, Seo’s operation would remove fast charges in a charge-trap memory.” (citing Ex. 1001, Abstract)). As already discussed, we disagree with this logic based on the lack of sufficient evidence to support its conclusion. See Dec. 13 (“Petitioner and Dr. Liu do not provide any objective evidence or explanation as to how or why a POSITA would have understood that Seo’s voltage amounts applied during Seo’s time periods operate the same way [as in the ’342 patent] on Seo’s memory device to generate fields with sufficient magnitude and duration to remove fast charges.”). Petitioner’s assertions regarding Nam suffer from the same shortcomings.

“These deficiencies in analysis raise the question of whether the Petition adequately identifies the number of actual challenges, and evidence supporting each, with the degree of particularity required of petitions in our forum. The Petition does not explain why so many grounds are necessary under the circumstances or why the Board should impose on Patent Owner the burden of defending against so many challenges. See generally Pet. An inter partes review based on 24 distinct grounds raised against a single claim, supported by analysis lacking in particularity, potentially burdens Patent Owner unduly and makes inefficient use of the Board’s resources. See PTAB Consolidated Trial Practice Guide (Nov. 2019),22 56 (“The AIA was ‘designed to establish a more efficient and streamlined patent system that will improve patent quality and limit unnecessary and counterproductive litigation costs.’” (quoting H.R.

“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

“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.

“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).

Petitioner discusses the terms a “data line having a broad-width portion” and a “scanning line having a broad-width portion” recited in claim 1, as well as a “data line having a broad portion” and a “scanning line having a broad-width portion” recited in claim 2. Petitioner cites the ’079 patent for “offering a lexicographic definition of the term ‘broad width’” to support the plain meaning interpretation of the terms “‘broad-width portion’ and ‘broad portion’ as a portion that is broader than another portion of the subject element.” Pet. 16. Patent Owner does not provide arguments directed specifically to Petitioner’s proposed claim constructions. See Prelim. Resp. 10–11. Taking account of the information presented, we determine that no claim term requires express construction for purposes of deciding whether to institute review. Compare Pet. 16 (addressing issues of claim construction, citing the ’079 patent for supporting the plain and ordinary meaning of “broad-width portion” and “broad portion” without demonstrating that an express construction is necessary to resolve whether to institute review), with Prelim.

“Id. (emphasis added). Sato ¶ 26 is entirely silent on scan lines and clearly links the cited benefits to “this arrangement” of “data lines composed of an Al film.” Id. Importantly, Petitioner does not connect Sato’s disclosure, relating to benefits associated with a data line arrangement, to any particular arrangement of scan lines. Sato ¶ 28 is equally deficient. Sato ¶ 28 also discusses benefits of utilizing a specific “arrangement,” namely, “capacitance lines formed of [a] metal film.” Id. ¶ 28. [0028] With this arrangement, the provision of the function as the shading layer with the capacitance lines formed of the metal film, the polysilicon film, or the like, in addition to the function as the wiring, as well as the provision of the function as the light absorption layer with the capacitance electrodes formed of the polysilicon film, or the like, in addition to the function as electrodes, prevents the laminated structure from becoming complex by additionally forming a dedicated shading layer and a dedicated light absorption layer. Accordingly, this arrangement is very advantageous by simply arranging the electro-optical device, and simplifies a manufacturing process thereof. Id. (emphasis added). Here again, Sato ¶ 28 is entirely silent on scan lines and clearly links the cited benefits to “this arrangement” of “capacitance lines formed of metal film.” Id. Petitioner does not bridge the gap in its rationale to combine by attempting to explain why an ordinarily skilled artisan would have extrapolated benefits, pertaining to an arrangement of capacitance lines, to a similar arrangement of scan lines. Petitioner’s witness, Dr. Flasck, provides no further insight as to how or why Sato ¶¶ 26 and 28 would have been understood to apply to scan lines. Dr. Flasck’s comments on Sato ¶¶ 26 and 28 merely repeat, nearly verbatim, the Petition’s conclusory contentions. See Ex. 1002 ¶ 139 (Dr. Flasck declaring “Sato specifically teaches that its device ‘is very advantageous by simply arranging the electro-optical device, and simplifies a manufacturing process thereof.’”); Pet. 37.

“view. First, as Petitioner admits, data line 6a is not connected to image signal line 101d and line 109 other than when sample hold circuit 101c connects them due to shift register 101b outputting an enabling signal. Pet. 49. This is supported by the layout of the four elements in Fujikawa’s Figure 2. Ex. 1005, Fig. 2 (depicting sample hold circuits 101c between and connecting data lines 6a and signal lines 101d). In addition, Patent Owner’s declarant, Dr. E. Fred Schubert, testifies that “two separate lines straddling circuitry are [not] one line.” Ex. 2001 ¶ 64. The dispute between the parties on this issue is largely one of claim construction: should the term “wiring line” in claim 7 be construed broadly enough to encompass a collection of lines separated by a sample hold circuit? In order to determine that Fujikawa discloses or teaches the recited wiring lines, we would need to answer this question in the affirmative. Yet, as discussed above, neither party proposes construing “wiring line,” or any other term used in the claims of the ’606 patent. Pet. 18; Prelim. Resp. 7. The failure to argue for and sufficiently support a broad construction of the term “wiring line” means that Petitioner does not show sufficiently, for purposes of supporting institution of review, that Fujikawa discloses or teaches the “wiring line” limitation of claim 7. b) Conclusion Regarding Claim 7 Based on the record presented, we determine that Petitioner has not shown that there is a reasonable likelihood that Petitioner will prevail in demonstrating that claim 7 is unpatentable as anticipated by or obvious in view of Fujikawa.” slip op. at 11
