“The Petition includes detailed arguments that map the limitations of the challenged claims to specific disclosures in Yu (Sample 1). Id. at 50–62. The Petition also maps adequately the limitations of the challenged claims to specific disclosures in Stewart (Example 2). Id. at 62–66. For example, Petitioner shows sufficiently that Yu (Example 1) coextrudes “a multilayered polymeric film,” that is, a “sheet,” arranged in the hard-soft-hard-soft-hard, five-layer configuration required by claim 11. Pet. 50–51; Ex. 1002 ¶¶ 124, 126–128; Ex. 1012 ¶¶ 63, 78, 92. Petitioner also shows sufficiently that the hard layers in that configuration of Yu (Example 1) are “hard” and the hard layers are “hard” within the meaning of claim 11. Pet. 53; Ex. 1002 ¶ 131; Ex. 1012 ¶ 78. In other words, Petitioner shows sufficiently, on this record, that Yu (Example 1) anticipates claim 11. Based on the information presented, we find that Petitioner shows sufficiently, for purposes of trial institution, that at least one challenged claim of the ’263 patent is anticipated by Yu (Sample 1).” slip op. at 12
- Disclosure Requirements (§112) › Written description (Ariad)Not entitled to earlier dateDecided for petitioner
“That prior art disclosure of elastomeric materials for use as the outer layers in an unclaimed and disfavored soft-hard-soft layer configuration does not convey, with reasonable clarity, that the inventors had possession of the claimed subject matter, in which the elastomeric material forms the inner layer of a polymeric sheet in a hard-soft-hard layer configuration. See id. ¶¶ 7, 33–35, 109–110. Even if the hardness limitation of the challenged claims would have been obvious from the relied-upon disclosure of the ’176 application (Ex. 2001 ¶ 109), that circumstance is insufficient to establish written description support. “Entitlement to a filing date does not extend to subject matter which is not disclosed, but would be obvious over what is expressly disclosed.” PowerOasis, Inc. v. T-Mobile USA, Inc., 522 F.3d 1299, 1306 (Fed. Cir. 2008) (quotations omitted); see Pet. 21 (quoting that precedent). Accordingly, we agree with Petitioner that the invention that Patent Owner seeks to protect in the ’263 patent does not appear to be “part of the invention” described in the ’176 application. Pet. 40; see Ex. 2001 ¶ 109 (describing elastomeric materials, having the specified hardness, only in the context of an unclaimed prior art soft-hard-soft embodiment). On this record, we preliminarily agree with Petitioner that the earliest effective filing date to which the ’263 patent appears to be entitled is December 18, 2019, namely, the filing date of the ’256 application, from which the ’263 patent issued. Ex. 1001, codes (21), (22). Patent Owner may contest this issue in a timely response to the Petition.” slip op. at 9
- Skill levelNot reached
“The parties disagree about whether the ordinarily skilled artisan would have had specific “experience with dental appliances or access to individuals with such experience.” Prelim. Resp. 17; see Pet. 14–15 n.1 (disagreeing with that proposition). Neither party explains why a resolution of that Stat. 284 (September 16, 2011), includes revisions to Section 102(a) that became effective on March 16, 2013. For reasons explained in this Decision, on this record it appears Petitioner is correct that the challenged claims are entitled to an effective filing date no earlier than December 18, 2019 and, therefore, the AIA provisions apply in this proceeding. See Pet. 22, 39–40; Ex. 1001, code (60). 2 WO 20010/043419 A1, published Apr. 22, 2010, with English Translation (Ex. 1015). 3 We take notice that the first and second grounds identified in the Petition assert anticipation based on the same prior art disclosure. 4 US Pub. 2004/0224283 A1, published Nov. 11, 2004 (Ex. 1008). dispute is necessary to this Decision to institute review. See, e.g., Prelim. Resp. 17 n.2 (“even under Petitioner’s proposed definition, the Petition fails to show a reasonable likelihood that any claim is unpatentable”); Pet. 14–15 & n.1 (arguing about the issue without explaining how a resolution of the dispute would change the outcome of the decision on institution). If either party believes that the difference in level of skill would have a material effect on the analysis of the patentability of the challenged claims, that issue should be specifically addressed in briefing during the trial. We will resolve that dispute only to the extent necessary in any final written decision. Based on the information presented, we find that the asserted prior art itself is sufficient to demonstrate the level of skill in the art at the time of the invention. See Okajima v. Bourdeau, 261 F.3d 1350, 1355 (Fed. Cir. 2001) (prior art itself can reflect the appropriate level of ordinary skill in the art).” slip op. at 6
- Claim Construction › Threshold & procedure › Whether a term needs construction (O2 Micro)No construction needed
“We construe terms in controversy 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) (quoting Vivid Techs., Inc. v. Am. Sci. & Eng’g, Inc., 200 F.3d 795, 803 (Fed. Cir. 1999)). “Petitioner discusses the terms “layer A,” “layer B,” “layer C,” “layer C,” “layer B',” inner layer B,” “inner layer B',” and “inner layer D.” Pet. 15–20. Patent Owner discusses the terms “layer” and “inner.” Prelim. Resp. 19–22. Taking account of the information presented, we determine that no claim term requires express construction for purposes of deciding whether to institute review. Compare Pet. 15–20 (addressing issues of claim construction, without demonstrating that an express construction is necessary to resolve whether to institute review), with Prelim. Resp. 19–22 (same).” slip op. at 7
