    “We also agree with Patent Owner that the charge cut-off voltage is not necessarily the applied voltage during charging. PO Resp. 20. Rather, depending on the charging protocol used and when in the charging cycle the voltage is applied, the applied voltage could be higher than the battery voltage. Ex. 2013; Ex. 2006 ¶ 91. For example, as discussed in more detail below with respect to the Uemura grounds, when fast charging using constant current is used and the charging rate is not slow, the applied voltage will be higher than the battery voltage when the constant current charging phase is stopped. Ex. 2006 ¶ 91; Ex. 2013. Likewise, during constant current/constant voltage charging, the applied voltage approximates the battery voltage only when the battery is nearly completely charged. Ex. 2013; Ex. 2006 ¶ 91. Thus, the applied voltage may be, but is not necessarily, the charge cut-off voltage.

First, we agree with Petitioner that the ’641 patent indicates that the charge cut-off voltage selected for a particular battery need not be a fixed property of the battery or something that is set by the design and chemistry of the battery.

We disagree with this assertion, however, because it relies on erroneously equating the output of calculations (i.e., |r1-rj| and |r1-ri+1|). In other words, Aksu’s difference calculations, although used in setting dr, are not the same as dr; and we are not persuaded that one of ordinary skill in the art would have considered comparing Gonzalez’s Laplacian output to threshold β because Aksu discloses comparing its difference calculations to β. As noted above, we are not directed to any disclosure in Aksu of comparing dr to β. In addition, Dr. Schonfeld’s testimony on this point is not persuasive. Specifically, Dr. Schonfeld testifies that “dr can simply be defined as the output of the Laplacian (dr=|r3-2r2+r1|), and dr could be directly compared to a threshold based on β.” Ex. 1003 ¶ 408 (underline emphasis added). This testimony, however, is entitled to little weight because Dr. Schonfeld fails to provide a sufficient underlying basis for his opinion. See 37 C.F.R. § 42.65(a) (“Expert testimony that does not disclose the underlying facts or data on which the opinion is based is entitled to little or no weight.”); see also Nobel Biocare Services AG v. Instradent USA, Inc., 903 F.3d 1365, 1382 (Fed. Cir. 2018) (explaining that the Board can reject arguments based on expert testimony that lacks specificity or detail). Moreover, opining that output of the Laplacian, dr, could be directly compared to β does not establish sufficiently that one of ordinary skill in the art would have been motivated to do so. See Belden Inc. v. Berk-Tek LLC, 805 F.3d 1064, 1073 (Fed. Cir. 2015) (“[O]bviousness concerns whether a skilled artisan not only could have made but would have been motivated to make the combinations or modifications of prior art to arrive at the claimed invention.”).” slip op. at 26

    “Dr. Schonfeld’s testimony cited by Petitioner does not rectify this problem. See Ex. 1003 ¶ 263. Dr. Schonfeld does not actually state that the well as the number of pixel differences, as “variables” that “were known to control the frequency response of the filter, or, in other words, how much particular frequencies would be filtered,” as allegedly shown by Gonzalez.9 Id. (citing Ex. 1020, 153, 273). But Dr. Schonfeld does not explain adequately how the cited portions of Gonzalez disclose that the coefficients were known to control the frequency response in a deblocking filter. Indeed, the cited portions of Gonzalez do not appear to discuss determining offsets for deblocking filtering or the coefficients used in an equation for determining offset. See Ex. 1020, 153, 273.

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.

    “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.

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
