    “We have reviewed the cited testimony of Clearwater’s expert, including their calculations for arriving at a coat weight in Nakagawa that falls within the claimed range. See Ex. 1003 ¶¶ 132–33. We find that testimony, which is unrebutted, both credible and supported by the evidence of record. Thus, in light of Clearwater’s contentions, the cited portions of Nakagawa, and the unrebutted testimony of Clearwater’s expert, we are persuaded that Nakagawa discloses or otherwise suggests each and every element of claim 1. See Pet. 45–54, 60–64. Clearwater also persuades us that Cleveland discloses the additional subject matter of dependent claims 2, 3, and 11. See Pet. 64–66. Thus, we determine that Clearwater demonstrates that claims 1–3 and 11 are unpatentable as obvious over Nakagawa. F. Ground 3—Obviousness Over Nakagawa and Tanner” slip op. at 17

We were persuaded by Clearwater’s proof that Cleveland’s provisional (Ex. 1006) is “virtually identical” to Cleveland itself (Ex. 1005) and that the provisional provides written description support for at least claim 1 of Cleveland. See Pet. 18–21 (citing Ex. 1006, 2–6, 9). We were also persuaded by Clearwater’s showing that the provisional provides written support for the subject matter relied upon in Cleveland.

    “protectant layers has “a coat weight of from 5 to 30 lbs/3000 ft2.” As noted by Clearwater, Cleveland discloses a total coat weight for layers 14 and 16 as falling within the claimed range. Pet. 32–34 (citing Ex. 1005 ¶ 32). In particular, Cleveland discloses that “the coextruded layer of copolyester (irrespective of which side of the substrate the layer is disposed) is of a total coat weight of between about 10 and about 40 lb/3000 ft2 in any combination of between about 80/20 to 20/80 parts by weight of Ecoflex to Biomax,” of which “a total coat weight of 25 lb/3000 ft2 is preferred.” Ex. 1005 ¶ 32. As disclosed, Cleveland’s total coat weight range of 10–40 lb/3000 ft2 falls almost entirely within the claimed range, and the preferred total coat weight of 25 lb/3000 ft2 falls squarely within the claimed range. Thus, Cleveland satisfies claim elements [1.3.2] and [1.5.2]. See Titanium Metals Corp. v. Banner, 778 F.2d 775, 782 (Fed. Cir. 1985) (“[W]hen, as by a recitation of ranges or otherwise, a claim covers several compositions, the claim is anticipated if one of them is in the prior art.”) (citation omitted).

    “Dr. Papanikolopoulos’s testimony that Kuwata teaches away from modifying its camera 22 to access an external server (such as Fisher’s Internet-enabled external data source) by stressing advantages of a self-contained camera-printer pair without external dependencies. See PO Resp. 15–16, 26–28 (citing Ex. 1005 ¶¶ 75, 77); Ex. 2001 ¶¶ 61–64. The cited disclosures in Kuwata simply do not discuss any advantages arising from a self-contained camera-printer pair without external dependencies, or any disadvantages arising from connecting camera 22 to an Internet server. See Ex. 1005 ¶¶ 75, 77. The cited disclosures instead tout the advantages arising from a camera manufacturer (rather than an end user photographer) specifying the image output control information CI for a specific camera-printer pairing, to reduce differences between an image as confirmed by the end user on the camera’s display and the image outputted by the printer. See id. That advantage, however, has nothing to do with whether camera 22 may or may not communicate with an Internet server. Indeed, rather than being self-contained as Patent Owner and Dr. Papanikolopoulos would have it, we find Kuwata’s camera 22 includes an I/O port for wired or wireless communication to transmit the camera’s image files GF / 10 to various printers 24 and various personal computers (PCs). See Ex. 1005, Fig. 4, ¶¶ 81, 85; Ex. 1003 ¶ 84; Pet. 14. Thus, Kuwata allows for and does not discourage communication between camera 22 and an Internet server such as Fisher’s external data source. In particular, Kuwata does not detract from the benefits of updating image output control information CI after the camera is manufactured, for example so that the camera can be paired with printers that were not yet on the market when the camera was manufactured. Moreover, Fisher recognizes that “a manufacturer may create various ancillary data files 418, and make the ancillary data files 418 available on a distributed computer network like the Internet for subsequent downloading and utilization by camera device 110.” Ex. 1006 ¶¶ 42, 55. That teaching in Fisher dovetails with Kuwata’s disclosure concerning camera manufacturers optimizing their cameras with various different printers, supporting Petitioner’s combination.

Envtl. Designs, Ltd. v. Union Oil Co., 713 F.2d 693, 696–97 (Fed. Cir. 1983). Not all factors may exist in every case, and one or more of these or other factors may predominate in a particular case.

    “Alleged Objective Indicia of Nonobviousness (i) General Principles Before reaching a conclusion about obviousness, we consider evidence concerning objective indicia of nonobviousness. See Apple, 839 F.3d at 1048. For such evidence to have substantial weight, “its proponent must establish a nexus between the evidence and the merits of the claimed invention.” ClassCo, Inc. v. Apple, Inc., 838 F.3d 1214, 1220 (Fed. Cir. 2016); see Ancora Techs., Inc. v. Roku, Inc., 140 F.4th 1351, 1361 (Fed. Cir. 2025) (noting that the Board did not err by requiring “a nexus to the challenged claims as opposed to the patent as a whole”). “[T]here is no nexus unless the evidence presented is ‘reasonably commensurate with the scope of the claims.’” ClassCo, 838 F.3d at 1220 (quoting Rambus Inc. v. Rea, 731 F.3d 1248, 1257 (Fed. Cir. 2013)). The patentee “bears the burden of showing that a nexus exists.” WMS Gaming, Inc. v. Int’l Game Tech., 184 F.3d 1339, 1359 (Fed. Cir. 1999).

    “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.

    “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.

    “To the extent Petitioner argues that Dr. Eldering does not meet the minimum qualifications of a POSITA, we disagree.

Inst. Dec. 8–9. Dr. Eldering holds a Ph.D. in electrical industry and, thus, less than 3–4 years of industry experience is required. Moreover, Dr. Eldering’s declaration, testimony, and CV demonstrate that Dr. Eldering has many years of industry experience with twisted pair data cables.
