      “testimony that we limit the level of ordinary skill to “refrigerated display cases.” Limiting the level of skill to an engineer with experience “working with refrigerated display cases” does not relate to the technology disclosed, and the invention claimed, in the ’847 patent, which is controlling condensation and conserving energy. E.g., Ex. 1001, 2:23–27 (“The invention is proactive in preventing condensation from forming by activating frame/door heaters before the dew point temperature at frame and door surfaces is reached. Power is then cycled off at a set point above dew point to save energy.” (emphases added)). An electrical engineer with a bachelor’s degree and 2 years of experience focused on lighting systems for refrigerated display cases would have “experience working with refrigerated display cases,” and thus meet Patent Owner’s proposed level of skill. Such a person, however, would not be experienced in controlling condensation, dew point sensor positioning, and condensation algorithm design, which is the focus of the disclosed and claimed invention, and which Mr. Pollock states “materially affect performance, energy use, and reliability” in controlling condensation in a refrigerated display case. Ex. 2037 ¶ 10. We also note that Mr. Pollock’s qualifications include a “B.S. in Mechanical Engineering, . . . with focus on thermal and mechanical systems, thermodynamics, and HVAC&R (Heating, Ventilation, Air Conditioning & Refrigeration).” Ex. 2037 ¶ 3. His academic focus is consistent with our determination of the level of ordinary skill. Accordingly, based on the prior art, the sophistication of the disclosed technology in the ’847 patent, finding Mr. Pollock’s testimony on this issue too general, and crediting Dr. Henze’s testimony with substantial probative weight, we adopt Petitioner’s definition of the level of ordinary skill.

      “The fundamental role of expert testimony is that “the expert’s scientific, technical, or other specialized knowledge will help the trier of fact [here, the Board] to understand the evidence or to determine a fact in issue.” Fed. R. Evid. 702(a). The testimony must be “based on sufficient facts or data” (id. at 702(b)); must be “the product of reliable principles and methods” (id. at 702(c)); and must reflect “a reliable application of the principles and methods to the facts of the case” (id. at 702(d)). We determine, based on the record before us, that Dr. Henze’s Declaration testimony meets these requirements. He provides, as required, the facts and data to support his testimony. Indeed, Federal Rule of Evidence 702 and the Code of Federal Regulations require him to do so. 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.”). Expert testimony that “merely repeats, verbatim, the conclusory assertion for which it is offered to support,” or that “does not cite to any additional supporting evidence or provide any technical reasoning to support” the testimony is entitled to little weight.

Reply 1–2 (district court construing the term to mean “the time the image sensor collects and integrates signal from the scene”). The specification states that the integrated photo-charge “is directly related to the time the image sensor collects and integrates signal from the scene,” and that “[t]his is known as integration time.” Ex. 1001, 4:4–7.

      “We construe “during a frame” to mean the period during which data for a single frame of an image is captured. The limitation is satisfied where the per-channel integration time is effectuated during the frame; it does not require that the integration time be re-determined mid-frame, nor does it require actuation of a “charge integration switch.” The specification’s only use of the phrase confirms this reading: “each camera channel is controlled during a frame under an independent integration time.” Ex. 1001, 3:45–50. Consistent with that usage, the specification describes selecting an integration time for each channel and then integrating the photo-signal “within a single frame of data,” and describes placing the charge-integration switch in a state to allow charge to accumulate for the selected period and then transferring the accumulated charge upon completion of the integration period. Id. at 4:51–54, 11:3–18. We decline Patent Owner’s proposal to require in-frame actuation of a charge-integration switch, for the same reason we decline to import that structure into “integration time.” We also decline to read the phrase to require mid-frame re-determination of the integration time, because the patent’s own embodiment selects an integration time and then integrates charge during the frame under that selected time. Ex. 1001, 4:51–54, 11:3– 18. So construed, “during a frame” is not redundant of the independentclaim limitation: it adds that the per-channel control occurs within a single frame (intrascene), as distinct from adjustment from one frame to the next (interscene).” slip op. at 15

Resp. 16 (citing Ex. 1001, 1:47–48; Ex. 2008 ¶ 37). This is consistent with the Specification, which explains: Users and software applications do not always refer to hosts or other resources by their numerical IP address. Instead of using numbers, they use ASCII strings called domain names. The Internet uses a Domain Name System (DNS) to convert a domain name to an IP address. Ex. 1001, 1:45–50. According to the Patent Owner, the network in the Specification of the ’785 patent is defined by the domain name X.VCN. Id. at 33 (citing Ex. 1001, 9:18–19, 9:28–31). Patent Owner further contends that “[t]he use of a domain name to define the virtual network in the ‘785 Patent’s claims provides more than an identifier of the virtual network or even a plain language identification of an IP address – it signifies a hierarchical structure for the virtual network that enables [certain functions].” Prelim.

Rather than explaining the “why,” the Petition’s motivation argument focuses on the purported capabilities of the resulting combination and implying, but not explicitly stating, that the combination results in the claimed subject matter; this indicates impermissible hindsight. See, e.g., id. at 29 (“This integration would leverage Hipp’s DNS capability for virtual hostnames to return multiple address records from a single query, aligning with the dual addressing requirements of hybrid virtual/physical networks. The combination creates a cohesive system where DNS resolution triggers context-aware routing decisions—using virtual addresses for internal Supernet traffic and NAT-translated addresses for cross-boundary communication.”). We determine that Petitioner has failed to set forth an adequate and persuasive reason with rational underpinning as to why a person of ordinary skill in the art would have combined the three references’ teachings to arrive at the claimed subject matter where the three recited addresses are returned in response to a DNS request.” slip op. at 21

      “onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3) (requiring inter partes review petitions to identify “with particularity . . . the evidence that supports the grounds for the challenge to each claim”)); see also 37 C.F.R. § 42.104(b) (requiring a petition for inter partes review to identify how the challenged claim is to be construed and where each element of the claim is found in the prior art patents or printed publications relied upon). This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). A patent claim is unpatentable under 35 U.S.C. § 103(a) when the differences between the claimed subject matter and the prior art are such that the subject matter, as a whole, would have been obvious at the time the invention was made to a person having ordinary skill in the art to which said subject matter pertains. KSR Int’l Co. v. Teleflex Inc., 550 U.S. 398, 406 (2007). The question of obviousness is resolved on the basis of underlying factual determinations including: (1) the scope and content of the prior art; (2) any differences between the claimed subject matter and the prior art; (3) the level of ordinary skill in the art; and (4) when in evidence, objective evidence of nonobviousness, i.e., secondary considerations.4 Graham v. John Deere Co., 383 U.S. 1, 17–18 (1966). Additionally, the obviousness inquiry typically requires an analysis of “whether there was an apparent reason to combine the known elements in the fashion claimed by the patent at issue.” KSR, 550 U.S. at 418 (citing In re Kahn, 441 F.3d 977, 988 (Fed. Cir. 2006) (requiring “articulated reasoning with some rational underpinning to support the legal conclusion of obviousness”)). Petitioner cannot satisfy its burden of proving obviousness by employing “mere conclusory statements,” but “must instead articulate specific reasoning, based on evidence of record, to support the legal conclusion of obviousness.” In re Magnum Oil Tools Int’l, Ltd., 829 F.3d 1364, 1380 (Fed.

      “and 4) does not address Petitioner’s first two arguments and evidence, which, on this record, appear to show that Bucknell’s prioritized queue length is based on buffered data in either, or both, of a first and second iteration. Therefore, at this stage of the proceeding, we need not reach Patent Owner’s assertions as to the third alternative argument and evidence Petitioner provides, namely the combination of examples 2), 3), and 4). For completeness, however, we acknowledge that Bucknell does not expressly combine examples 2), 3), and 4), mainly because example 4) only refers back to example 2). However, we note that from a plain reading of Bucknell’s written description it may not be a significant leap to understand that the disclosed combination of examples 2) and 4), with first and second portions 90 and 95 populated in reverse order as taught in example 4), that this combination could be subsequently modified by example 3) to provide a “second iteration . . . based on buffered data.” Ex. 1006 ¶¶ 26–27. In other words, on the current record it is not clear why “the unused resource” of Bucknell’s second portion 95 cannot also “be made available,” to the first portion 90 if the order was simply reversed per the combination of examples 2) and 4). 3. Conclusion as to Claim 1 In summary, we find Petitioner’s arguments and evidence sufficient to show a reasonable likelihood that claim 1 is unpatentable over Eckert in view of Bucknell and Lohr-1. On the current record, we find that Bucknell discloses “a first iteration” based on receiving the priority values for logical channels associated with the MAC-d flows. Ex. 1006 ¶ 26. And, as discussed above, Bucknell’s described “priorities,” are plural, just like the claimed “received parameters.” Ex. 1001, 14:11; Ex. 1006 ¶ 26. In on a priority.” See Ex. 1001, 13:57–14:16. As to the issue of whether the Petition provides sufficient explanation or motivation to combine Bucknell’s examples 2), 3), and 4), which is an alternative argument to Petitioner’s other mappings for limitation [1.9] which we find sufficient for institution, we leave this alternative mapping issue for development at trial.

      “of Choi to support its argument that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed. See Pet. 61–62. With only this explanation and evidence from Petitioner and Dr. Jenson, however, we cannot not discern how these portions of Choi would have so apprised an ordinarily skilled artisan. For example, the side view of the infrared lamp housing, illustrated in Figure 5 reproduced below, shows the housing having a convex, rather than concave, shape. See Ex. 1008, Fig. 5. Furthermore, paragraphs 20 and 48 refer to the housing’s “circular” shape and outer periphery and also “tubular” shape. See id. ¶¶ 20, 48. But these descriptions, either alone or together with Figure 5, also do not support adequately a finding that Choi’s housing is concave. Choi’s teachings in paragraphs 20 and 46 regarding the lamp housing guiding or directing infrared light from the lamp to irradiate the skin of a user, without more, are similarly deficient. See id. ¶¶ 20, 46. And although Dr. Jensen appears to equate “concave” with “inner circular,” he does not provide the basis for his testimony or explain what “inner circular” means, particularly in the context of distinguishing a convex shape from a concave shape. See Ex. 1002 ¶ 197. Accordingly, we determine there is insufficient evidence to support Petitioner’s conclusory statements that an ordinarily skilled artisan would have understood Choi’s infrared lamp housing to define a concave shape as claimed.” slip op. at 23

      “Record evidence supports Petitioner’s contentions that a skilled artisan would have had reason to look to Kumar for further implementation details of a circuit that performs functions like those performed by Fujiyoshi. See Pet 24–26. For example, Dr. Young testifies that a person of ordinary skill in the art would have recognized that Kumar discloses the details, at a granular level, of Fujiyoshi’s capacitive sensing systems and would have looked to Kumar for understanding of how to implement Fujiyoshi’s system. Ex. 1002 ¶ 145. Patent Owner does not point to persuasive evidence to rebut this opinion. Moreover, Petitioner cites to Kumar, not only for an explicit disclosure of capacitive pickoff signals, but also for its disclosure of both DC bias and AC carrier signals and recognizing the applicability of an AC carrier pickoffs that operates without DC bias.
