“The Federal Circuit found that “[t]he factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan,” concluding “[n]othing more is required to establish a motivation to combine.” Everstar II, 2025 WL 1501940, 4. The Federal Circuit observed that “Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1,” and accordingly, “reverse[d] the Board’s patentability determination as to that claim and vacate[d] the Board’s judgment as to the remaining claims of the ’037 patent,” remanding to us for further proceedings. Id. at 4–5. With those instructions in mind, we review the Petitioner’s allegations regarding claims 2–33.” slip op. at 6

“F. Person of Ordinary Skill in the Art In the First Final Written Decision, we determined that a person of ordinary skill in the art “would have (1) at least two years of experience in the design of decorative lighting, or (2) at least a bachelor’s degree in mechanical engineering, electrical engineering, or an equivalent field, and a basic familiarity with circuits used in decorative lighting.” Paper 40, 12. We see no reason to depart from that earlier determination.” slip op. at 12

“The parties agree that we do not need to construe any claim terms. Pet. 8–9; PO Resp. 16–17. We likewise agree. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed.

- Obviousness (§103) › Motivation to combine / reasonable expectation of successMotivation foundDecided for petitioner
“Patent Owner did not dispute that the combined teachings of Kumada and Debladis ’120 disclose each limitation of claim 1. Patent Owner, however, did dispute Petitioner’s proposed reasons for combining Kumada and Debladis ’120, and argues that Debladis ’120 is not analogous art. PO Resp. 36–61. The Federal Circuit stated that substantial evidence only supports the conclusion that a POSA would have been motivated to combine the teachings of Kumada and Debladis ’120. The factual record and Willis’s concession on appeal conclusively establish that the cost of copper was a known problem in the art, Debladis ’120 (and Kumada) helped address that issue, and Willis has not disputed that combining the teachings of Kumada and Debladis ’120 was within the skill of an ordinary artisan. Nothing more is required to establish a motivation to combine. Given that Willis has conceded that the combination of Kumada and Debladis ’120 disclose all the limitations in claim 1, we reverse the Board’s patentability determination as to that claim and vacate the Board’s judgment as to the remaining claims of the ’037 patent. Everstar II, 2025 WL 1501940, 4 (internal citations omitted). The Federal Circuit further noted Patent Owner’s secondary considerations arguments as to claim 1 and stated [t]he cited evidence consists only of a temporal connection between the introduction of Willis’s invention and the UL 588 standards, and deposition testimony of a single witness who seemingly disclaimed any connection between the two. This is not sufficient to rescue a claim as to secondary considerations. Id. at 4, n. 5 (internal citations omitted). Accordingly, the Federal Circuit ruled that claim 1 would have been obvious over Kumada and Debladis ’120. 6. Analysis of Independent Claim 33” slip op. at 17

- Skill levelSkill level patent owner adoptedDecided for patent owner
“the invention “would have had at least a Bachelor of Science degree (or equivalent) in Electrical Engineering, or a comparable field, and at least five years of experience in the fields of design of electrical wiring and/or decorative lighting.” Pet. 9 (citing Ex. 1009 ¶ 21). Patent Owner argues that Petitioner’s proposed definition recites an unnecessarily high level of skill. Prelim. Resp. 21. Patent Owner contends that the appropriate level of ordinary skill “would have been (1) a technician with at least two years of experience in the design of electrical wiring and/or decorative lighting, or (2) a person with at least a bachelor’s degree in mechanical engineering, electrical engineering, or an equivalent field, and a basic familiarity with circuits used in decorative lighting.” Id. (citing Ex. 2001 ¶¶ 14–15). At this stage in the proceeding, we determine that the current record supports Patent Owner’s description of an ordinarily skilled artisan. For purposes of this Decision, therefore, we adopt Patent Owner’s description of an ordinarily skilled artisan.7 We also note that the applied prior art reflects the appropriate level of skill at the time of the claimed invention. See Okajima, 261 F.3d at 1355.” slip op. at 8

“Neither party offers any proposed constructions for any claim terms. Pet. 8–9; Prelim. Resp. 20. Specifically, Petitioner indicates, “no terms require a specific construction, as they would be readily understandable to a [person of ordinary skill in the art].” Pet. 9 (citing Ex 1009 ¶ 22). Patent Owner also indicates, for purpose of its Preliminary Response, that no claim construction is necessary at this stage, but reserves the right to propose constructions should trial be instituted. Prelim. Resp. 20. On this record and for purposes of this decision, we determine that no claim term requires express construction. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (citing Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)).” slip op. at 10

“gauge of Sylvania’s net lights. Prelim. Resp. 24. Petitioner provides Exhibit 1007, which is a series of photographs of the Sylvania net lights, its packaging, and its inserts from the box. See Ex. 1007; see also Ex. 1010 ¶ 7 (describing Ex. 1007 as “a collection of photographs”). Petitioner also submitted Exhibit 1010, which is a declaration from William Shelleman describing the purchase of Sylvania. See Ex. 1010. Finally, Dr. Fantone’s declaration includes a description of Sylvania. Ex. 1009 ¶ 28. We have reviewed Petitioner’s evidence and we agree with Patent Owner that Petitioner has not established the wire gauge of Sylvania’s net lights because none of these documents purport to indicate the gauge of the wires in Sylvania. Thus, the question is whether the recited wire gauge teaches the asserted combination.” slip op. at 16
