“Petitioner contends that a person of ordinary skill in the art “would have had a Master’s degree in material science, chemical engineering, chemistry, or similar field with four years of experience designing testing, and building secondary lithium batteries.” Pet. 11 (citing Ex. 1002 ¶ 51). Petitioner further contends that a person of ordinary skill in the art would have been aware of “(1) positive electrode materials, (2) negative electrode materials, (3) separators, (4) electrolytes, (5) charge-discharge parameters, and (6) protection circuits, as well as ‘battery failure modes’ such as plating and the formation of dendrites.” Id.

“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. In view of the foregoing, we construe “charge cut-off voltage” in claims 1 and 5 as “the maximum value to which the battery is configured to be charged.” PO Resp. 18; Ex. 2008, 217:6–11; Pet. Reply 5. Contrary to Patent Owner’s arguments, however, we do not understand the phrase “configured to be charged” to necessarily represent a single voltage for the battery that is determined based on the structure and chemistry of the battery. Pet. Reply 4–5. Rather, the charge cut-off voltage is a selected potential, or voltage, of the battery or cell at the end of charging that is controlled by a circuit or device, such as a charger or control circuit within the battery. Ex. 1001, 9:50–55; Ex. 1048, 2, 7–8; Ex. 1008, 3:9–13. And, for the reasons discussed herein, the charge cut-off voltage may be, but is not necessarily, the same as the applied voltage during charging. PO Resp. 20.” slip op. at 15

“constructions. 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. Consistent with this conclusion, the ’641 patent discloses that a “charging device controls the charge cut-off voltage of the single lithium-ion cell within a range from 4.3 V to 5.8 V.” Ex. 1001, 9:50– 55. This strongly suggests that the charge cut-off voltage is controlled by the charger and is not necessarily an inherent property of the battery. Patent Owner contends that this is merely an unclaimed embodiment, but the relevant disclosure states that the charging device for the “present invention” may be any type of device “with the proviso that said charging device controls the charge cut-off voltage.” Id. at 9:50–53.” slip op. at 12

Tivoli, LLC, 742 F.3d 973, 977 (Fed.

Microsoft Corp. v. Proxyconn, Inc., 789 F.3d 1292, 1298 (Fed. Cir. 2015), overruled on other grounds by Aqua Prods., Inc. v. Matal, 872 F.3d 1290 (Fed. Cir. 2017). Upon our review of the entire record, we agree with the construction of “selectable betting parameter” previously provided by the Board, during ex parte prosecution of the ’952 patent, as set forth above. Therefore, for the reasons provided in that previous Board decision, none of which are disputed here, we apply that construction here. 2.” slip op. at 9

“However, the Federal Circuit has “cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.” In re Am. Acad. of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004); Teleflex, Inc. v. Ficosa North America Corp., 299 F.3d 1313, 1327–28 (Fed. Cir. 2002); In re Paulsen, 30 F.3d 1475, 1480 (Fed. Cir. 1994). We find no such clear disclaimer in the ’952 patent specification that would require Patent Owner’s narrow interpretation of the “corresponding” claim term. In particular, while any given location in the cited example from the ’952 patent corresponds to one value of the parameter so the location “determines the bet input” (Ex. 1001, 2:20–22), there is no clear disclosure that other locations may not correspond to that same parameter. It is only in one “example” that each different location “corresponds to a different roulette number.” Id. at 2:22–24 (emphasis added). Thus, the ’952 patent disclosure does not clearly disclaim multiple different locations each corresponding to the same bet input (number or color). See id. at 2:12–31.” slip op. at 12

“After full consideration of the foregoing arguments, we conclude Patent Owner’s analysis of the scope of the claim limitation at issue is vague and confusing. That claim limitation is: the first and second selectable betting parameters are different such that selecting one would cause a different result for the bet than selecting the other. Ex. 1001, 35:23–28. Such language, on its own, presents a straight-forward claim requirement. Patent Owner’s overlying varnish suggesting that the claim requires a relationship between the first and second parameters, making them “comparable variables,” is not supported by the claim language at issue, and confuses Patent Owner’s analysis of the prior art at issue. We reject Patent Owner’s implicit claim construction of this claim limitation and determine no explicit claim construction of this limitation is needed to resolve the issues presented by the arguments and evidence of record. 4. Remaining Claim Terms The parties do not offer any further explicit claim constructions. We determine no further explicit claim constructions are needed to resolve the issues presented by the arguments and evidence of record. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co.

“We agree with Patent Owner that Petitioner’s reference to video game experience, as opposed to some other computer gaming experience, is not required to achieve ordinary skill in the art pertinent to the ’952 patent. The ’952 patent is concerned principally with implementing different gaming rules via computer hardware and software as a mobile gaming device moves between jurisdictions; the specific technical implementation of presenting the game on a computer screen is only a secondary consideration. See, e.g., Ex. 1001, Abstract. However, even if we were to accept Petitioner’s position on this point, it would not affect the bases for our decision set forth below. We agree with Petitioner that ordinary skill here requires gaming experience, and does not encompass telecommunications experience without gaming experience. While wireless communication and location tracking are components of the ’952 patent’s claimed invention, the specifics of how such communication and tracking occur is only a secondary consideration. See, e.g., Ex. 1001, Abstract, 1:51–2:11, 7:48–8:12. However, even if we were to accept Patent Owner’s position on this point, it would not affect the bases for our decision set forth below. We determine a person of ordinary skill in the art pertaining to the ’952 patent would have a Bachelor of Science Degree in Electrical Engineering, Computer Engineering, or a similar field.

“We agree with Petitioner. Although Figures 4 and 5 of the ’960 patent show keys that are partially surrounded by shadowing or shading, there is no suggestion in the Specification that the “blended shadow” recited in the claims should be limited to only this shadowing. The claim language itself, referring to a blended shadow of the representation of at least one key and the main image (see claim 24), indicates explicitly that the blended shadow incorporates both the key image and the main image and, thus, should not be limited to the shadowing surrounding the keys. Accordingly, based on the full record, we adopt Petitioner’s proposed construction of “blended shadow” as “a portion of a composite image in which the main image is visible through the overlaid image as a result of combining the data from corresponding pixels from the main and overlaid images” for the purpose of this Final Written Decision.

At best, Petitioner’s arguments suggest how Gough could be envisioned as using logical operators, but do not explain adequately where or how Gough expressly discloses using logical operators to carry out the blending process.
