“several threads, lines, cords, robes, ribbons, flat wires, sheets, or tapes. The Specification supports such interpretation. Ex. 1001, 9:21–23. Nevertheless, as Patent Owner argues, Petitioner’s interpretation is incomplete and does not address persuasively the dispute raised here— whether the “filament,” as recited in claim 1, requires flexibility. Based on the parties’ arguments at this preliminary stage, we agree with Patent Owner that flexibility is necessary. The claims, as understood by the POSA, suggest that the filament must be flexible. Claim 1 “recites that ‘the first filament [is] formed into a loop around the collapsible tubular sidewall” and that the “diameter of the valve lumen decreases in response to reducing a diameter of the loop.” See supra Section II.D. As Dr. Zalesky credibly explains “[t]o ‘reduc[e] a diameter of the loop,’ the filament must be ‘flexible’ because if it were rigid or inflexible the loop would retain the same diameter when acted on by the first actuator.” Ex. 2001 ¶ 58 (“This inherent property of flexibility is essential to the loop structure of the claims.”). We observed essentially the same principle in the related 1157 IPR for embodiments where the filament forms a “loop” around the collapsible tubular member, such as shown in Figure 6 of the patent.

See e.g., Ex. 1001, 10:17–11:14, 12:65–13:8, 14:20–24. On the whole, however, we do not discern on this record how specific experience in textile engineering and fiber science of a person of ordinary skill would materially alter the outcome at this stage of the proceeding. For purposes of this decision only, we apply Patent Owner’s proposed definition of a person of ordinary skill in the art, except for the requirement of five years of experience in measurement and analysis of coefficient of friction. The level of skill in the art remains an open issue in this proceeding. Further submissions by the parties may include argument and evidence that would assist in the resolution of this issue at the close of trial.” slip op. at 8
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction neededNot reached
“Petitioner contends “no formal claim construction is necessary in this proceeding.” Pet. 10; Reply 1, 4. Patent Owner contends the terms “mesh layer” and “coefficient of friction” require construction. Prelim. Resp. 14–16; Sur-reply 2–5. We have considered the parties’ arguments and discuss them below with regard to each of the terms Patent Owner contends should be construed. Because our determination that Petitioner demonstrates at least one challenged claim meets the threshold for institution (see SAS Inst., 138 S. Ct. at 1359–60) is not based on construing the term “mesh layer” or “coefficient of friction,” we determine we need not construe either claim term at this stage of the proceeding. 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) (“[O]nly those terms need be construed that are in controversy, and only to the extent necessary to resolve the controversy.”)). As further discussed below, we invite the parties to address claim construction at trial.” slip op. at 9
- Claim Construction › Intrinsic evidence (Phillips canons) › Specification disavowal / 'present invention' languageDisclaimer not foundDecided for petitioner
“We agree with Petitioner that the ’854 patent specification does not include clear and explicit lexicography or a disclaimer that would support requiring “coefficient of friction” to be determined by a specific ASTM test method. The portion of the specification Patent Owner asserts as a definition of “coefficient of friction” (see Ex. 1001, 11:31–42) is a description of an embodiment; we find it does not express patentee intent to redefine the term. Further, the statement that “the coefficient of friction … may be determined using the … ASTM D1894 standard test method” (id. at 11:32–35) indicates that use of that specific test method is optional. Accordingly, in the absence of patentee lexicography or disavowal, we do not limit the scope of the term “coefficient of friction” to require that it be measured by a specific ASTM standard. Luminara Worldwide, LLC v. Liown Elecs. Co., 814 F.3d 1343, 1353 (Fed. Cir. 2016) (“Absent lexicography or disavowal, we do not depart from the plain meaning of the claims.”); In re Am. Acad. Of Sci. Tech Ctr., 367 F.3d 1359, 1369 (Fed. Cir. 2004) (“We have cautioned against reading limitations into a claim from the preferred embodiment described in the specification, even if it is the only embodiment described, absent clear disclaimer in the specification.”). We note that the ’854 patent specification sets forth a definition for the coefficient of friction between the surfaces of the mesh material and the slide surface. Ex. 1001, 4:38–46. As stated above, however, we do not expressly construe any claim term at this stage of the proceeding. Should the parties address the construction of “coefficient of friction” at trial, we will make a determination after the close of evidence and any hearing.” slip op. at 13

“Institution of an inter partes review is authorized by statute when “the information presented in the petition . . . and any response . . . shows that there is a reasonable likelihood that the petitioner would prevail with respect to at least 1 of the claims challenged in the petition.” 35 U.S.C. § 314 (2018); see also 37 C.F.R. § 42.4 (2023). For the reasons discussed below, we determine that Petitioner establishes a reasonable likelihood of prevailing with respect to the unpatentability of at least one claim of the ’202 patent. Accordingly, we institute an inter partes review of claims 1, 3, 4, 8–13, and 15 of the ’202 patent. A. Real Parties in Interest” slip op. at 2

On this record, we preliminarily adopt Petitioner’s undisputed proposed definition because it appears to be consistent with the cited prior art and the disclosure of the ’202 patent. See Okajima v.

For purposes of this Decision, we adopt the Board’s prior construction of “wicked into contact,” namely, “wicked into contact (1) with the heater, or (2) with an area in close proximity to, and exposed to the heat produced by, the heater,” which is undisputed on this record.

“To establish anticipation, each and every element in a claim, arranged as recited in the claim, must be found in a single prior art reference. Net Karsten Mfg. Corp. v. Cleveland Golf Co., 242 F.3d 1376, 1383 (Fed.
