      “In the Response, Patent Owner states that it “does not dispute” the definition of one of ordinary skill in the art proposed by Petitioner, but Patent Owner “reserves the right to address [the definition] should new issues materialize.” PO Resp. 5. Patent Owner did not address this issue in the Sur-reply. As noted in the Decision on Institution, Petitioner’s proposed definition appears generally consistent with the record, including the prior art. See Dec. Inst. 8 (citing In re GPAC Inc., 57 F.3d at 1579). We remove the phrase “at least” in both listed options, however, as that phrase adds ambiguity. Further, Patent Owner has not argued at trial that Petitioner’s proposal for the level of ordinary skill leads to an improper understanding of how a skilled artisan would have understood either the challenged patent or the prior art. In the analysis below, we continue to apply the level of ordinary skill in the art adopted in the Decision on Institution, as proposed by Petitioner.” slip op. at 9

      “The record here does not support any sound basis to disregard the entirety of Dr. Micklow’s Declaration, as asserted in Petitioner’s overall argument. See Pet. Reply 1–2. Contrary to Petitioner’s argument, in the cited general discussion, Dr. Micklow does not indicate that he applied an incorrect understanding of a claim term. Cf. Cordis Corp. v. Bos. Sci. Corp., 658 F.3d 1347, 1357–58 (Fed. Cir. 2011) (disregarding testimony “based on an incorrect understanding of the claim construction”), cited at Pet. Reply 1; see also Pet. Reply 2 (arguing that “Dr. Micklow’s declaration is premised on understandings of claim scope that are inconsistent with the constructions advanced by both of the parties” (emphasis added)). Instead, we read the cited portions of Dr. Micklow’s testimony as clarifying that he was not involved in claim construction at all and that, as stated, he “made [his] opinions based on what [he] read in the patents.” Ex. 1046, 112:11–12; see also Pet. Reply 1 (citing Ex. 1046, 112:4–12, 113:13–20, 115:15–18). Next, we turn to each of the four specific claim terms that Petitioner highlights in its further arguments.” slip op. at 12

      “B. Claim Construction In inter partes reviews, the Board interprets claim language using the same claim construction standard that would be used in a civil action under 35 U.S.C. § 282(b), as described in Phillips v. AWH Corp., 415 F.3d 1303 (Fed. Cir. 2005) (en banc). See 37 C.F.R. § 42.100(b). Under that standard, we generally give claim terms their ordinary and customary meaning, as would be understood by a person of ordinary skill in the art at the time of the invention, in light of the language of the claims, the specification, and the prosecution history. See Phillips, 415 F.3d at 1313–14. Although extrinsic evidence, when available, may also be useful when construing claim terms under this standard, extrinsic evidence should be considered in the context of the intrinsic evidence. See id. at 1317–19. Neither Petitioner nor Patent Owner propose explicit constructions for any claim terms. Pet. 10–11; PO Resp. 5. Based on the complete record, we need not construe explicitly any claim terms because doing so would not change the outcome of the analysis below. See Realtime Data, LLC v. Iancu, 912 F.3d 1368, 1375 (Fed. Cir. 2019) (“The Board is required to construe ‘only those 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)).” slip op. at 9

      “Florida Litigation a Joint Claim Construction statement that included stipulated claim constructions and disputed claim constructions for terms in the challenged patent as well as the ’449 patent and the ’918 patent. See Ex. 1018, Exhibit A (Stipulated Claim Constructions), Exhibit B (Disputed Claim Constructions). The parties stipulated to the construction of the terms “fluid dispersion” and “baffle” as recited in the challenged claim. See id., Exhibit A.10 10 When staying the Florida Litigation, the District Court cancelled the scheduled claim construction hearing. See ECF No. 67 (April 8, 2025) (granting joint motion to stay); ECF No. 68 (April 8, 2025) (cancelling the The stipulated construction of “fluid dispersion” merely restates the express definition of “fluid dispersion” from the challenged patent (although the definition is not cited or discussed in the parties’ filing). Compare Ex. 1018, Exhibit A, with Ex. 1001, 3:8–20. Similarly, the stipulated construction of “baffle” essentially parrots one sentence in the challenged patent (again, not cited or discussed in the parties’ filing). Compare Ex. 1018, Exhibit A, with Ex. 1001, 7:57–59. To the extent necessary, we determine that the complete record supports the parties’ stipulated constructions of “fluid dispersion” and “baffle,” and we apply those constructions below.” slip op. at 10
