“Institution of a post-grant review is authorized by statute when “the information presented in the petition . . . would demonstrate that it is more likely than not that at least 1 of the claims challenged in the petition is unpatentable.” 35 U.S.C. § 324(a) (2018). Upon consideration of the parties’ submissions and the evidence of record, we determine that Petitioner has demonstrated that it is more likely than not that at least one claim challenged in the Petition is unpatentable. Further, Patent Owner has not persuaded us that it is appropriate to exercise our discretion not to institute review. Accordingly, we institute a post-grant review of all claims and all grounds asserted in the Petition.1” slip op. at 2

“On this record, we do not find Patent Owner’s proposed experience level of at least five years in measurement and analysis of coefficient of friction to be supported. As to the necessity of experience in textile engineering and fiber science, Patent Owner’s position, although not supported by declarant analysis of the factors listed above, is consistent with the disclosure of the ’854 patent, which describes features of a mesh layer in textile and fiber terms. 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.

- 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

“evaluated the subject matter of Riis during examination of the ’624 patent, we agree that Riis was before the Office, as discussed in connection with our analysis of the first part of the Advanced Bionics framework, above. Examiner T presumably was aware of Riis by virtue of having initialed an IDS containing Riis in the ’624 patent’s application and also by virtue of having initialed an IDS containing Riis in the ’067 Application, but Examiner T did not apply Riis in connection with the examination of the ’624 patent. On this record, Patent Owner also fails to show that the claims of the child application leading to the ’624 patent are substantially similar to those of the parent ’814 patent in which Examiner S considered Riis, and, thus, consideration of Riis during the prosecution of the ’814 patent does not equate to consideration of Riis during the prosecution of the ’624 patent. Regarding Patent Owner’s argument (2) that Petitioner fails to sufficiently show how the Examiner erred in evaluating the prior art, we find Petitioner’s arguments demonstrate that Examiner T, the examiner of the ’624 patent, did not apply Riis (or Wypych or Tatarka) during the examination of the’624 patent. As Petitioner argues, the error lies in that “the Examiner failed to consider the relevance of Riis as it applied to the pending method claims,” because although “Riis was considered during examination of the parent ’999 application, Riis was not similarly considered during examination of the ’018 application which led to the ’624 patent.” Pet. 76–77.

Patent Owner argues that the Petition “should also have identified its parent corporation, Huhtamäki Oyj . . . as well as the related corporation Huhtamaki, Inc. . . . as RPIs to comply with the statutory requirements for a PGR.” Id. at 10. On this record, we determine that we need not address whether Huhtamäki Oyj and Huhtamaki, Inc. are unnamed RPIs because, even if they were, it would not create a time bar or estoppel under 35 U.S.C. § 325. See SharkNinja Operating LLC v. iRobot Corp., IPR2020-00734, Paper 11 (PTAB Oct. 6, 2020) (precedential); Lumentum Holdings, Inc. v. Capella Photonics, Inc., IPR2015-00739, Paper 38 at 6 (PTAB Mar. 4, 2016) (precedential) (Board’s jurisdiction to consider a petition does not require a “correct” identification of all RPIs in a petition); see also Blue Coat Sys., Inc. v. Finjan, Inc., IPR2016-01444, Paper 11 at 10 (PTAB July 18, 2017) (“evidence [of failure to identify all RPIs] is, at best, suggestive regarding an issue that is not jurisdictional”); Mayne Pharma Int’l Pty.

Here, notwithstanding the arguments devoted to the RPI issue in the Preliminary Response, Preliminary Reply, and Preliminary Sur-Reply, we are not persuaded that Petitioner is barred or estopped from this proceeding, or that Petitioner purposefully omitted Huhtamäki Oyj or Huhtamaki, Inc. to gain some advantage. As Petitioner argues, the “RPI analysis is not necessary at institution, because Patent Owner has not alleged Petitioner would be time barred or otherwise estopped based on unnamed RPIs.” Prelim. Reply 5 (quoting SharkNinja, IPR2020-00734, Paper 11 at 18). As SharkNinja states, certain Board decisions go through extensive analysis to determine whether parties should have been named as RPIs, whereas other Board decisions determine that “such a lengthy exercise is unnecessary for the purposes of rendering a decision on institution of trial.” SharkNinja, IPR2020-00734, Paper 11 at 19. Here, as in SharkNinja, we find the latter approach better serves the interest of cost and efficiency. Thus, at this time and on this record, we will not consider whether Huhtamäki Oyj or Huhtamaki, Inc. must be named as RPIs.” slip op. at 15

- Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner
“the ’176 grandparent application is insufficient. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” Lockwood v. Am. Airlines Inc., 107 F.3d 1565, 1571–72 (Fed. Cir. 1997); see also Reply 5–6. We find that the cited disclosures in the ’176 grandparent application do not describe the density, size, depth, or height of the deformities at approximate midpoints between adjacent pairs of light sources. As discussed above, Patent Owner maintains that a skilled artisan reading the ’176 grandparent application would know that “the approximate midpoint between the two light sources is an area farther away from a light source.” PO Resp. 28 (emphasis added). We are not persuaded by this argument, for it does not establish that the approximate midpoint between adjacent pairs of light sources is the only area farther away from a light source. As Petitioner points out, “the increased distance from the light source is not limited to a distance along the length of the panel member, along the width of the panel member, or along any direction at all.” Reply 11. Thus, Patent Owner fails to meet its burden under Dynamic Drinkware, LLC v. National Graphics, Inc., 800 F.3d 1375, 1379–80 (Fed.

Therefore, we determine that claims 1–5 are not entitled to the benefit of the filing date of the ’176 grandparent application and Patent Owner is thus entitled only to the effective filing date of the application for the ʼ973 patent, February 9, 2007. As a consequence, we find that Shinohara qualifies as prior art.” slip op. at 11
