“Resp. 7–8. Patent Owner contends that “a POSITA is a person with a masters or doctorate degree in chemistry and/or chemical engineering, and having at least 3 years of experience working on the research, development, manufacture and formulations of HFC, HCFC and HFO compounds and mixtures.” Id. at 8 (citing Ex. 2003 ¶ 23). Patent Owner’s declarant Dr. Thrasher testifies, however, that he has “reviewed Dr. Sandford’s definition of a person of ordinary skill in the art” and his opinions “do not change under Dr. Sandford’s definition.” Ex. 2003 ¶ 24. We agree with the parties that a POSITA would have had an advanced degree in chemistry or chemical engineering, and experience in the research, development, and/or manufacture of hydrofluorocarbons (HFC) and hydrofluoroolefins (HFO), which is consistent with the level of ordinary skill in the art at the time of the invention as reflected in the prior art in this proceeding. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (explaining that specific findings regarding ordinary skill level are not required “where the prior art itself reflects an appropriate level and a need for testimony is not shown” (quoting Litton Indus. Prods., Inc. v. Solid State Sys. Corp., 755 F.2d 158, 163 (Fed. Cir. 1985))). Our determination regarding Petitioner’s challenge does not turn on the differences between Petitioner’s and Patent Owner’s definitions, and we note that our conclusions would be the same under either definition.” slip op. at 6

“under 35 U.S.C. § 282(b), which is articulated in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005). 37 C.F.R. § 42.100(b); see also Changes to the Claim Construction Standard for Interpreting Claims in Trial Proceedings Before the Patent Trial and Appeal Board, 83 Fed. Reg. 51,340 (Oct. 11, 2018) (applicable to inter partes reviews filed on or after November 13, 2018). Under Phillips, claim terms are afforded “their ordinary and customary meaning.” Phillips, 415 F.3d at 1312. “[T]he ordinary and customary meaning of a claim term is the meaning that the term would have to a person of ordinary skill in the art in question at the time of the invention.” Id. at 1313. Only those terms in controversy need to be construed, and only to the extent necessary to resolve the controversy. See Nidec Motor Corp. v. Zhongshan Broad Ocean Motor Co., 868 F.3d 1013, 1017 (Fed. Cir. 2017) (“[W]e need only construe terms ‘that are in controversy, and 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)). Petitioner does not propose a construction for any of the claim terms. Pet. 21–22. For purposes of this Decision, based on the record before us, we determine that no claim term requires explicit construction.” slip op. at 6

“sufficiently establishes that Rao ’434, Rao ’781, and Rao ’597 disclose compositions comprising HFO-1234yf, 3,3,3-trifluoropropyne, and at least one additional compound, as recited in independent claims 1, and 7 of the ’709 patent, or compositions comprising HFC-245eb, 3,3,3- trifluoropropyne, and at least one additional compound as recited in independent claim 11 of the ’709 patent. The ’709 patent states that the examples present a “general procedure [that] is illustrative of the method used for analyzing the products of fluorination reactions.” Ex. 1001, 12:30– 33. Examples 1, 2, and 3 of the ’709 patent use that procedure to measure the reaction product of (1) vapor phase dehydrofluorination of HFC-245eb to HFO-1234 with fluoride alumina catalyst, (2) pyrolysis of HFC-245eb, and (3) liquid phase dehydrofluorination of HFC-245eb to HFC-1234yf, respectively. Id. at 13:1–14:16. Although the ’709 patent provides the amounts of a number of different reaction products detected in each example, i.e., HFO-1234yf, HFO-1234ze, and HFC-245eb, notably absent is a measurement for 3,3,3-trifluoropropyne. Id. There is no indication, therefore, that the products in the examples of the ’709 patent represent the claimed compositions of the ’709 patent, each of which requires the presence of 3,3,3-trifluoropropyne.” slip op. at 15

“this result. An experiment reproducing or recreating an example falls within the scope of that example so long as the reproduction is consistent with the teachings of the example, any deviations are immaterial, and the reasons for any deviations are adequately explained. See, e.g., Purdue Pharma L.P. v. Epic Pharma, LLC, 811 F.3d 1345, 1357 (Fed. Cir. 2016) (finding “no clear error” in the district court’s determination that the prior art application’s process was recreated “fairly, accurately, and with no material variation”); Glaxo Inc. v. Novopharm Ltd., 52 F.3d 1043, 1047 n.4 (Fed. Cir. 1995) (finding no error in the district court’s determination that one skilled in the art would have understood that testing departing from the “strict letter” of a prior art example was nonetheless consistent with that example). Based on the current record, we are not persuaded that Petitioner sufficiently establishes that its replication of Rao ’434’s example falls within the scope of the example.” slip op. at 19
