As such, Rezvani-875 would not have suggested to one of ordinary skill in the art that providing a headset with multiple wireless connections would produce undesirable battery drain. Accordingly, we are not persuaded that one of ordinary skill in the art would have been dissuaded from using two wireless connections because of increased battery usage.” slip op. at 28

      “B. Person of Ordinary Skill in the Art The parties propose similar definitions of a person of ordinary skill for the ’213 patent. See Pet. 15–16; Prelim. Resp. 18; PO Resp. 18. In our institution decision, we adopted Patent Owner’s proposal that “[a] person of ordinary skill for the ’213 patent would have had a Ph.D. or equivalent in chemistry, biochemistry, structural biology, or a closely related field, and experience with antibody structural characterization, engineering, and/or biological testing, or an M.D. with practical academic or industrial experience in antibody development.” Dec. 8. Petitioners do not contest this definition in its Reply and we find no reason to revise our earlier determination.” slip op. at 11

      “variable domain,” which appears in claims 4, 33, 62, and 69, to mean “a human variable domain which comprises the most frequently occurring amino acid residues at each location in all human immunoglobulins of any particular subclass or subunit structure.” Prelim. Resp. 18–19; PO Resp. 19. Patent Owner correctly points out that this “construction comes directly from the definition provided in the ’213 patent.” Prelim. Resp. 19 (citing Ex. 1001, 11:32–38). Petitioners expressly adopt this construction in their Reply. Pet. Reply 5–6. We do not agree, however, that the claims demand a consensus of “all” human immunoglobulins in the literal sense. Indeed, Petitioners point out that “the ‘consensus’ sequence used for the patent variants was generated using the most common residue at each position identified in [Kabat 198711].” Pet. Reply 15 (citations omitted). And though Patent Owner attempts to distinguish Queen 1990 as describing “a consensus framework from many human antibodies,’ not all as in the ’213 patent,’” it presents no argument as to why we should interpret the claim in this manner. 11 Kabat et al., Sequences of Proteins of Immunological Interest: Tabulation and Analysis of Amino Acid and Nucleic Acid Sequences of Precursors, V- Regions, C-Regions, J-Chain, T-Cell Receptor for Antigen, T-Cell Surface Antigens β2-Microglobulin, Major Histocompatibility Antigens, Thy-1 Complement, C-Reactive Protein, Thymopoietin, Post-Gamma Globulin, and α2-Macroblobulin, 41–175 (4th Ed. 1987). Ex. 1052. See PO Resp. 47. Moreover, in a parallel proceeding involving the same patent, Patent Owner did not dispute that the reference to “all sequences” in the patent, “refer[s] to all known sequences and there’s no dispute . . . that was really synonymous with Kabat 1987.” See IPR2017-01374 Paper 82, Tr. 15:4–16:4; see Ex. 1202 ¶ 157; Ex. 2105 ¶¶ 24–25; Ex. 2107 ¶¶ 18–19; Ex. 1198, 56:20–61:24; Ex. 1199, 27:14–28:13, 29:25–36:2, 57:1–58:6, 115:7–17, 165:17–169:9. Indeed, in a similar parallel proceeding, counsel for Patent Owner acknowledged that the term “all human immunoglobulins” refers to “all reasonably available[,] all known at the time of the invention.” IPR2017-01373, Paper 83, 47:21–48:5. Accordingly, we adopt the parties’ proposed construction, with a clarifying modification, specifically, “a human variable domain which comprises the most frequently occurring amino acid residues at each location in all human immunoglobulins of any particular subclass or subunit structure, as set forth in Kabat 1987.”” slip op. at 13

    • Claim Construction › Intrinsic evidence (Phillips canons) › Plain and ordinary meaning to a POSITATerm construed board ownDecided for patent owner

      “lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient.” In our institution decision, we determined that this claim language “refer[s] to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” Dec. 10–12. Neither party disputes this interpretation. See PO Resp. 19; Pet. Reply 5–6. Consistent with claim 63’s express comparison between the immunogenicity of the claimed humanized antibody and that of its non-human parent, the Specification states that one object of the invention is to “to provide methods for the preparation of antibodies which are less antigenic in humans than non-human antibodies but have desired antigen binding and other characteristics and activities.” Ex. 1001, 4:24–28. The Specification similarly states that embodiments within the scope of the claims have “low immunogenicity,” or are designed to “minimize the potential immunogenicity of the resulting humanized antibody in the clinic.” Id. at 52:54–58, 61:56–61. Moreover, with reference to claim 63 in particular, Patent Owner points to the ’272 application as “explain[ing] that the purpose of humanizing antibodies using its consensus sequence approach is to reduce immunogenicity versus the non-human parent antibody. (Id., 6:24–30, 84:24–30.).” Prelim. Resp. 42 (citing Ex. 2032 (File History for U.S. Patent Application No. 07/715,272 (“the ’272 application”)); see also id. at 38 (indicating that the limitation is satisfied where “[o]nly 1 out of 885 patients experienced an immunogenic response . . . which was a substantial improvement over the murine 4D5 antibody”). In light of the above, we do not alter our prior determination that “[a] humanized antibody which lacks immunogenicity compared to a non-human parent antibody upon repeated administration to a human patient,” refers to a humanized antibody having reduced immunogenicity in a human patient as compared to its non-humanized parent antibody.” slip op. at 14

      “It “remains true in construing patent claims before the PTO” that “the prosecution history . . . serves as intrinsic evidence for purposes of claim construction.” Tempo Lighting, Inc. v. Tivoli, LLC, 742 F.3d 973, 977 (Fed. Cir. 2014). “The PTO should also consult the patent’s prosecution history in proceedings in which the patent has been brought back to the agency for a second review,” such as the present inter partes review. 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. Ltd., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (per curiam) (claim terms need to be construed “only to the extent necessary to resolve the controversy”) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).” slip op. at 16

    • Skill levelSkill level petitioner adoptedDecided for petitioner

      “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. Such a person, further, would have at least about two years of experience designing and developing computer hardware and software to be used for playing games.” slip op. at 18

      “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.

      “We agree with Patent Owner. Petitioner does not explain adequately where the detailed analysis set forth in the Reply is made in the Petition, and, in any event, we do not find the arguments persuasive. “A patent claim is anticipated if a single prior art reference expressly or inherently discloses every limitation of the claim.” DDR Holdings, LLC v. Hotels.com, L.P., 773 F.3d 1245, 1252 (Fed. Cir. 2014). Here, Petitioner does not describe sufficiently how Gough expressly discloses using logical operators to accomplish the blending process.6 We do not agree that either Gough’s description of the blending process depicted in Figures 10a–10f (Ex. 1007, 10:23–41) or Gough’s description of using the color look-up table (id. at 14:9–19) expressly discloses using logical operators, and such express disclosure is required for anticipation. 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. For these reasons, we are not persuaded that Petitioner has shown, by a preponderance of the evidence, that independent claim 1, and claims 2, 3, 5, 7–10, and 12–14 depending therefrom, are anticipated by Gough.” slip op. at 15

      “3. Harrison Petitioner also argues Harrison teaches certain limitations. Pet. 44, 48, 52–55. Petitioner does not explain what Harrison adds to what is taught by Buxton. See id. at 48 (“[t]o the extent that these features may not be fully disclosed in Buxton, they are clearly disclosed in Harrison”). For purposes of this Final Written Decision, we determine the teachings of Harrison are cumulative to the teachings of Buxton, and therefore, do not address Harrison further.7 4. Claims 1–3, 5, 7–10, and 12–14 Petitioner argues that “Buxton discloses nearly all of the elements and limitations” of the challenged claims. Pet. 42. With respect to claim 1, Petitioner argues that Buxton discloses using alpha blending in accordance with the equation I = αI1 + (1-α)I2, where I is the resulting color intensity, I1 is the color intensity of the foreground image pixel, I2 is the color intensity of the background image pixel, and α is the specified transparency level between 0 and 1. Id. at 43–44 (citing Ex. 1009, 17:17–28). Petitioner argues that Buxton’s alpha blending “permits pixels to be ‘dedicated simultaneously’ to both images in order to produce a composite image” and is an “example of an operation using logical operators to provide different blending effects.” Id. at 44 (citing Ex. 1009, 16:63–17:4). Petitioner contends that although “Buxton may lack explicit disclosure of . . . a touchactivated device (required in claims 1 and 26),” Bier discloses that a touch screen is interchangeable with a mouse. Id. at 44–45. Petitioner also contends that Bier discloses a keyboard superimposed over a display. Id. at 7 Because the asserted ground includes Harrison, we continue to include it as part of our overall analysis.” slip op. at 23

      “After considering all evidence and arguments, we agree with Patent Owner. In particular, we determine that Petitioner’s arguments do not persuade us that Buxton’s alpha blending equation uses operators that manipulate binary values at the bit level, consistent with our construction of “logical operators.” The alpha blending equation unquestionably involves arithmetic operations, which we find differ from logical operations. Furthermore, Petitioner has not shown persuasively whether any logical operations overlap with any arithmetic operations. Therefore, we agree with Patent Owner’s contention that Buxton’s alpha blending equation does not use logical operators.” slip op. at 24
