    “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

    “Further, because Bowen’s disclosed barrier height is outside the claimed range, Petitioner relies on Soukup’s purported teaching of a barrier height of “about 0.33 eV” and contends that a person of ordinary skill in the art would have been motivated to “achieve” that barrier height for the MgO barrier of Bowen’s device. Id. at 34–36. The data that Petitioner relies on from Soukup for the “about 0.33 eV” barrier height, though, was determined using the slope of an Arrhenius plot, not Simmons’ formula. Ex. 1028, 3229 (Abstract), 3231–33, Table I. In Soukup, apparent barrier heights for the samples were determined using (1) the slope of an Arrhenius plot, and (2) the zero-field intercept of the straight line logI versus V1/2 plot. Id. at 3229 (Abstract), 3230–32, Fig. 3, Table I. Reproduced below is Table I of Soukup, as annotated by Patent Owner (Prelim. Resp. 39): Annotated Table I of Soukup includes the results of analyses of sample test data, with the column highlighted in yellow showing the barrier heights obtained by a zero-field intercept method and the column highlighted in blue showing barrier heights obtained from the slope of an Arrhenius plot. See Ex. 1028, 3233; Prelim. Resp. 38–39. Dr. Bokor testifies that “Soukup disclosed that Simmons’ formula was used to approximate tunnel barrier height” and “[o]ne of skill would have understood the ‘height and the bias dependence of the insulator potential-energy barrier’ [referenced in Soukup] included the tunnel barrier height.” Ex. 1024 ¶¶ 145–147 (quoting Ex. 1028, 3229; citing Ex. 1024 ¶¶ 45–49). We do not find this testimony persuasive. Although Soukup refers to “Simmons’ model” and the Simmons 1963 paper in its “Introduction,” it does not teach any calculation using Simmons’ formula to obtain a barrier height within the claimed range. See Ex. 1028, 3229, 3236 n.1; Prelim. Resp. 63. Soukup plainly recognizes that there are methods of calculating barrier height other than Simmons’ formula, and discusses at length its calculations using two such methods: the Arrhenius plot method and the zero-field intercept method. See, e.g., Ex. 1028, 3229 (Abstract) (“These results . . . indicate a potential barrier height of about 0.72 eV when determined from the zero-field intercept of the straight line logI vs V1/2 plot and about 0.33 eV when obtained from an Arrhenius plot.”), 3232–33. Petitioner does not address whether the 0.33 eV barrier height it relies on from Soukup (determined using the Arrhenius plot method) would still be within the claimed range if calculated using Simmons’ formula. See Prelim. Resp. 63. Nor does Petitioner rely on any values from Soukup’s disclosure that would be used as the variables in Simmons’ formula—Petitioner relies solely on Bowen. See Pet. 39–42. Thus, Petitioner’s argument that Bowen and Soukup teach a barrier height within the claimed range, obtained using equation (1), is not persuasive. See id. at 34–42.” slip op. at 17

    “Importantly, Soukup indicates a different relationship between the amount of oxygen vacancy defects in the barrier layer and the barrier height, depending on which method is used. Specifically, Soukup explicitly found that “[t]he apparent barrier height determined from the zero-field intercept went up for increasing oxygen pressure [(i.e., less oxygen vacancy defects)] and the barrier height determined from the Arrhenius plot went down.” Ex. 1028, 3229 (Abstract) (emphasis added).15 That disclosure is reflected in Table I, where Soukup shows the results for three fabricated samples with increasing oxygen pressure during MgO deposition. Id. at 3233. Patent Owner provides another annotated version of Table I below (Prelim. Resp. 45): 15 Soukup’s conclusion appears to refer to the trend of the respective increasing or decreasing barrier heights values under the two different mathematical analyses methods. Annotated Table I above shows (in red) that the barrier height decreases as oxygen vacancies increase (i.e., as the oxygen pressure admitted during MgO deposition, shown in the PO2 column, decreases) using the zero-field intercept method, and shows (in blue) that the barrier height increases as oxygen vacancies increase (i.e., as the oxygen pressure admitted during MgO deposition decreases) using the Arrhenius plot method. Prelim. Resp. 45. In other words, Petitioner’s alleged inverse relationship is present for the zero-field intercept method, but not for the Arrhenius plot method. See id.; Pet. 37–38. “The barrier height cannot both increase and decrease with more oxygen vacancy defects,” and Petitioner does not attempt to reconcile or explain Soukup’s disparate teachings. See Prelim. Resp. 45 (emphasis omitted). We agree with Patent Owner that Petitioner is inconsistent in relying on one method as allegedly teaching a barrier height within the claimed range, while at the same time relying on the other method for a motivation under its obviousness theory. Prelim. Resp. 45–49. If a person of ordinary skill in the art would have understood that the Arrhenius plot method was the appropriate method for determining barrier height, as Petitioner argues in asserting that Soukup teaches a barrier height of 0.33 eV, that person would have understood that “the barrier height increases as oxygen vacancies increase” (in blue above), and Petitioner’s obviousness theory of adding oxygen vacancies to lower Bowen’s barrier height is incorrect. See id. at 47. If, however, a person of ordinary skill in the art would have looked to the zero-field intercept method, that person “would have understood that all of Soukup’s tested samples . . . had barrier heights” (in yellow above) “above the claimed range of 0.2–0.5 eV.” See id. at 48.

Ex. 1062, 18:55–59 (“The simple cubic crystalline MgO layer thus provides a template for the formation of a thin crystalline ferromagnetic layer which has the bcc structure of CoFe and is oriented in the same (100) direction as the MgO layer.” (emphasis added)).” slip op. at 12

    “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.

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).

Cir. 2017) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). 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

    “‘run[ning] generally parallel to the lateral extent of a semiconductor material or semiconductor carrier’” and that “[t]he ’481 patent . . . describes a device that ‘has a lateral drift path.’” Pet. 24 (quoting Ex. 1001, 3:14–18, 4:37–38). Patent Owner directs us to a statement in the prosecution history that “[a] lateral transistor is a transistor in which current flows across ‘in the direction parallel to’ the device surface,” as opposed to “a vertical transistor,” in which “[c]urrent ‘flows in the direction normal to’ the device surface.” Prelim. Resp. 8 (quoting Ex. 1002, 33–34). Thus, the parties generally agree that a lateral transistor is a transistor in which current flows in a direction parallel to the surface of the transistor. Petitioner argues that Nega teaches or suggests a transistor in which current flows parallel to the surface because Nega’s source, gate, and drain electrodes “are spread laterally in a lateral drift path, instead of vertically stacked.” Pet. 24–25 (citing Ex. 1005, Fig. 2). Patent Owner argues to the contrary that the placement of source, gate, and drain electrodes in the same lateral plane, rather than in a vertical stack, does not necessarily indicate that the current flow within the transistor is parallel to the surface. Prelim. Resp. 47–48 (citing Ex. 2002, 7–8, Figs. 1.7a, 1.7c). According to Patent Owner, transistors with electrodes in the same horizontal plane can have either lateral or vertical current flow. Id. Thus, Patent Owner argues, the lateral placement of the source, gate, and drain electrodes in Nega does not mean that Nega teaches or suggests a lateral transistor. On the present record, we agree with Patent Owner that Petitioner has not shown sufficiently that Nega teaches a transistor in which current flows in a direction parallel to the surface, rather than in a direction normal to the surface. Transistors with current flow in either direction can have electrodes located on a common horizontal plane, with the direction of the current flow depending on the configuration of doped semiconductor regions located below the electrodes. Ex. 2002, Figs. 1.7a, 1.7c. Because Petitioner relies on the location of Nega’s electrodes, rather than on any particular configuration of doped semiconductor regions in Nega, Petitioner does not show sufficiently that Nega teaches a lateral transistor.” slip op. at 10
