      “E. Credibility of Dr. Doolittle Patent Owner argues that we should give no weight to Dr. Doolittle’s testimony because, “[o]n cross examination, Prof. Doolittle repeatedly contradicted himself, dodged questions, and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions.” PO Resp. 25. Patent Owner raises two major complaints about Dr. Doolittle. First, Patent Owner argues that he took inconsistent positions by asserting in these IPR proceedings that the claims were entitled to their plain and ordinary meaning, while in the parallel district court proceeding, asserting that certain claim terms were indefinite. Id. at 26–28. Second, Patent Owner argues that Dr. Doolittle “repeatedly dodged questions and tried to shoehorn new and nonresponsive opinions into his answers to Patent Owner’s questions,” and that “[d]uring cross examination Patent Owner was forced to object to Prof. Doolittle’s nonresponsive answers no less than eighteen times.” Id. at 28. We strongly disagree with Patent Owner’s characterization of Dr. Doolittle’s testimony. We have reviewed the entirety of both of Dr. Doolittle’s depositions. We are impressed with his forthrightness, candor, and good humor in the face of Patent Owner’s counsel’s aggressive questioning. Contrary to Patent Owner’s assertions, we find that his testimony was well-reasoned, forthright, honest, and entitled to significant weight. Dr. Doolittle explained the different claim construction positions We also strongly disagree that Dr. Doolittle’s answers were nonresponsive or “evasive” as Patent Owner argues. Patent Owner’s numerous attempts to “strike” portions of his testimony belie Dr. Doolittle’s efforts to honestly and in good faith respond to Patent Owner’s counsel’s questions. Ex. 2025, 22:10–23:15, 25:9–26:14, 30:14–22, 40:3-9, 58:12–59:1, 60:18–61:13, 65:1–10, 83:15–84:16, 92:15–95:20, 96:18–99:9, 102:22–106:16, 135:3–136:22. An answer is not “non-responsive” simply because it does not conform to the conclusion you want or undermines the logic underlying your questioning. Dr. Doolittle explained his answers and addressed the issues Patent Owner asked about. Accordingly, we decline Patent Owner’s invitation to give Dr. Doolittle’s testimony no weight. Instead, we assess Dr. Doolittle’s testimony on a case-by-case basis as discussed below.” slip op. at 21

    • Skill levelOther

      “B. Level of Ordinary Skill in the Art We consider the asserted ground of unpatentability in view of the understanding of a person of ordinary skill in the art (“POSITA” or “POSA”). In assessing the level of ordinary skill in the art, various factors may be considered, including the “type of problems encountered in the art; prior art solutions to those problems; rapidity with which innovations are made; sophistication of the technology; and educational level of active workers in the field.” In re GPAC Inc., 57 F.3d 1573, 1579 (Fed. Cir. 1995) (quoting Custom Accessories, Inc. v. Jeffrey-Allan Indus., Inc., 807 F.2d Relying on the declaration testimony of its expert, Dr. Doolittle, Petitioner contends that an ordinarily skilled artisan for the ’678 patent “would have had an undergraduate degree (i.e., B.S., B.S.E. or the equivalent) in electrical engineering, materials science, physics, or a similar discipline” and “would also have one to two years of experience in the field of LED packaging design.” Pet. 5–6. Petitioner additionally contends that “[m]ore education could substitute for experience, and vice versa.” Id. Petitioner further contends that “[t]his person would have been capable of understanding and applying the teachings of the ’678 patent and the prior-art references discussed herein,” and “[m]oreover, the prior art reflects the level of skill at the time of the claimed invention.” Id. (citing Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001); Ex. 1102 ¶¶ 38–42). Patent Owner states that “solely for the purposes of this proceeding, Patent Owner and its technical expert employ the same level of skill in the art as Petitioners.” PO Resp. 24–25. Thus, we adopt Petitioner’s articulation of the level of ordinary skill in the art, which is consistent with the ’678 patent and the asserted prior art, and we apply it in our obviousness analysis below.” slip op. at 10

      “lower wavelength might offer, there were other drawbacks that a person of ordinary skill would have to balance. But “a given course of action often has simultaneous advantages and disadvantages, and this does not necessarily obviate motivation to combine.” Medichem, S.A. v. Rolabo, S.L., 437 F.3d 1157, 1165 (Fed. Cir. 2006). Indeed, Petitioner has shown several references—including, Basin-2005, Shimizu, and Stokes—that made this tradeoff. Moreover, “[o]bviousness does not require absolute predictability of success. . . . [A]ll that is required is a reasonable expectation of success.” In re O’Farrell, 853 F.2d 894, 903–04 (Fed. Cir. 1988). We find that the prior art of record demonstrates that a person of ordinary skill in the art at the time of the invention would have such an expectation in making the combination of Basin-2007 and Basin-2005. Accordingly, we find that Petitioner has shown by a preponderance of the evidence that there would have been motivation to combine Basin-2007 and Basin-2005 with a reasonable expectation of success. 4. Summary We have reviewed Petitioner’s contentions regarding claims 1–3, 6, 9, 10, 16–21, and 25 (Pet. 19–53), and find that Petitioner has shown by a preponderance of the evidence that Basin-2007 and Basin-2005 teach the limitations of those claims, and that there would have been a motivation to combine the references in the manner suggested with a reasonable considerations does not outweigh the strong showing of obviousness. Accordingly, we find that Petitioner has shown by a preponderance of the evidence that claims 1–3, 6, 9, 10, 16–21, and 25 would have been obvious over Basin-2007 and Basin-2005.” slip op. at 41

      “person of ordinary skill in the art would have understood that Zeira’s RRC message includes MAC timer information. Zeira explicitly discloses that the calculated duration information is transmitted to the WTRU. Ex. 1005 ¶ 74.

Patent Owner did not file a Preliminary Response disputing Petitioner’s position. Based on the record presented, including our review of the ’243 patent and the types of problems and solutions described in the ’243 patent and cited prior art, we agree with Petitioner’s proposed definition of the level of ordinary skill in the art and apply it for purposes of this Decision, except that we remove the term “at least” to eliminate vagueness as to the amount of education and practical experience.” slip op. at 10

      “any reasonable construction.” Pet. 7. Patent Owner did not file a Preliminary Response disputing Petitioner’s position. We conclude that no express interpretation of any claim term is necessary to determine whether to institute a post-grant review in this proceeding.4 See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“Because we need only construe terms ‘that are in controversy, and only to the extent necessary to resolve the controversy,’ we need not construe [a particular claim limitation] where the construction is not ‘material to the . . . dispute.’” (citation omitted) (emphasis added)). 4 The parties, however, are encouraged to address during trial (1) interpretation of the term “user profile” in the challenged claims, particularly in view of the Specification’s apparent definition of the term “profile” (see Ex. 1001, col. 14, ll. 51–55) and description of exemplary data from which a “user profile” may be generated (id. at col. 18, ll. 40–58), and (2) the scope of the various instances of the phrase “in response to” in the challenged claims. Also, if either party intends to argue a claim interpretation during trial, including what the plain and ordinary meaning of a term is, the party should do so in a clearly designated section of its briefing. See Patent Trial and Appeal Board Consolidated Trial Practice Guide (Nov. 2019), 44–49, available at https://www.uspto.gov/ TrialPracticeGuideConsolidated; O2 Micro Int’l Ltd. v. Beyond Innovation Tech. Co., 521 F.3d 1351, 1361 (Fed. Cir. 2008) (“A determination that a claim term ‘needs no construction’ or has the ‘plain and ordinary meaning’ may be inadequate when a term has more than one ‘ordinary’ meaning or when reliance on a term’s ‘ordinary’ meaning does not resolve the parties’ dispute.”).” slip op. at 11

      “Petitioner’s Motion addresses each of these considerations. Mot. 1–8. According to Petitioner, its “[P]etition challenges the validity of the same claims of the ’868 patent on identical grounds to those in the T-Mobile IPR,” “[t]here are no substantive differences between [Petitioner’s] and the T-Mobile IPR Petitioners’ Petition,” and “[Petitioner] also relies on the same supporting evidence.” Id. at 4–5.

In light of these considerations, Petitioner has shown that joinder to the T-Mobile IPR is appropriate in this case. Therefore, we grant Petitioner’s Motion for Joinder.” slip op. at 8

      “Petitioner bears the burden to demonstrate unpatentability. Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015). At this preliminary stage, we determine whether the information presented in the Petition shows a reasonable likelihood that Petitioner would prevail in establishing that at least one of the challenged claims would have” slip op. at 4

      “Petitioner further identifies that Shah similarly teaches calculating operational efficiency values for an HVAC system and using these values “to monitor the integrity of the thermal system.” Id. at 17–18 (quoting Ex. 1006, 4:63–5:10). Petitioner matches these and other teachings in combination with Hildebrand to each of the limitations of claim 1. Id. at 17– 10:32–36, 11:59–61, 12:2–20, Fig. 1; Ex. 1002 ¶¶ 61–140). Petitioner also provides an extensive discussion of the reasons to combine Shah with the system of Hildebrand, such as to avoid being limited, like Hildebrand, to comparisons of system efficiencies between time periods with the same outside temperature. Id. at 19; see also id. at 18–24. We have reviewed the Petition and supporting evidence and determine that the Petition demonstrates a reasonable likelihood that Petitioner would prevail in showing that claim 1 is unpatentable over Hildebrand alone or in combination with Shah.3” slip op. at 6
