    The Board denied institution for claims 1–17 under § 314(a), finding the parallel litigation favored denial and the petition did not present compelling merits.

    • PTAB / AIA Trials › Discretionary denial › Fintiv (parallel litigation)Institution denied fintivInstitution denied

      “Concerns about the degree of overlap may be mitigated where a petitioner agrees not to pursue in the parallel proceeding the grounds advanced in the petition. Sand Revolution II, LLC v. Continental Intermodal Group – Trucking LLC, IPR2019-01393, Paper 24 at 11–12, 12 n.5 (June 16, 2020) (informative). “The PTAB will not discretionarily deny institution of an IPR . . . in view of parallel district court litigation where a petitioner stipulates not to pursue in a parallel district court proceeding the same grounds as in the petition or any grounds that could have reasonably been raised in the petition.” Fintiv Memo, 7–8 (emphasis added); Sotera Wireless, Inc. v. Masimo Corp., IPR2020-01019, Paper 12 at 18–19 (PTAB Dec. 1, 2020) (precedential as to § II.A). Here, Petitioner’s stipulation extends to the same grounds raised in the Petition, but does not extend to any ground “that could have been reasonably raised,” pursuant to Sotera. Patent Owner points to the narrowness of the proffered stipulation in the Sur-Reply and asserts this factor “only marginally weighs in favor of institution.” Sur-Reply 3. Because Petitioner’s stipulation obviates some potential for duplication or redundancy with respect to the patentability of the challenged claims (albeit not to the extent a full Sotera-type stipulation would have) and the parallel litigation does not include claims 10–16, we determine that the fourth Fintiv factor weighs against denial of institution.” slip op. at 15

      “A claim is anticipated only if each and every element as set forth in the claim is found, either expressly or inherently described, in a single prior art reference.” Verdegaal Bros., Inc. v. Union Oil Co. of Cal., 814 F.2d 628, 631 (Fed. Cir. 1987). “Inherent anticipation requires that the missing descriptive material is ‘necessarily present,’ not merely probably or possibly present, in the prior art.” Trintec Indus., Inc. v. Top-U.S.A. Corp., 295 F.3d 1292, 1295 (Fed. Cir. 2002) (quoting In re Robertson, 169 F.3d 743, 745, (Fed. Cir. 1999)). “[T]he reference must not only disclose all elements of the claim within the four corners of the document, but must also disclose those elements arranged as in the claim.” Sanofi-Synthelabo v. Apotex, Inc., 550 F.3d 1075, 1083 (Fed. Cir. 2008) (internal quotation marks omitted). In other words, it is not enough to be able to find all of the pieces of the claimed invention somewhere in a prior art reference; rather, those elements must be set out in the prior art reference in the same way they are in the claimed invention. Net MoneyIN, Inc. v. VeriSign, Inc., 545 F.3d 1359, 1369 (Fed. Cir. 2008) (“Because the hallmark of anticipation is prior invention, the prior art reference—in order to anticipate under 35 U.S.C. § 102—must slip op. at 17

      “As discussed above, “[c]ompelling, meritorious challenges are those in which the evidence, if unrebutted in trial, would plainly lead to a conclusion that one or more claims are unpatentable by a preponderance of the evidence.” Fintiv Memo 4. While the Petition and Dr. Gido provide an explanation for the full range in which Iwai’s D90 necessarily would be found, the Petition and Dr. Gido identify only a single value for the adhesive porous layer thickness of Iwai’s Example 7 and Comparative Example 2. Pet. 48, 51; Ex. 1003 ¶¶ 165, 174. The Petition and Dr. Gido direct us to the average thickness “a” of Iwai’s adhesive porous layer without taking into account Iwai’s disclosure of the ratio of the average thickness layer “a” to the volume average particle diameter “r.” Iwai describes the volume average particle diameter “r” being “projected at a proper height . . . formed on a surface of the adhesive porous layer.” Ex. 1006 ¶ 43. Thus, the evidence of record purportedly mapping claim 1’s recited “thickness of the porous layer” to Iwai does not plainly lead to a conclusion that Iwai necessarily discloses to a POSA the claimed “ratio of Dv90 of the inorganic particles to the thickness of the porous layer is in a range from 0.3 to 3.0.” Consequently, Petitioner does not present a compelling, meritorious challenge to claim 1 as anticipated by Iwai.” slip op. at 23

    • Obviousness (§103) › Motivation to combine / reasonable expectation of successNot shown unpatentableNot shown unpatentable

      “In addition to the lack of support in the record for the Petition and Dr. Gido’s assumption that the porous layer thicknesses of Examples 4 and 5 are the same as the porous layer thickness of Example 1 discussed above in connection with the anticipation challenge of claim 1, the cited record does not plainly support Petitioner’s assertion that Nishikawa teaches or suggests claim 10’s recited “uniform coating solution.” The Petition acknowledges that Nishikawa teaches a mixed solvent containing DMAc and TPG to provide a coating slurry. Pet. 31; Ex. 1003 ¶ 64; Ex. 1005, 22:26–33 (Example 4), 22:46–51 (Example 5). Nishikawa teaches that the solvent mixture includes a polar solvent (DMAc preferred) and a poor solvent (such as TPG) that “induces a microscopic phase separation structure to facilitate formation of pores upon providing the heat resistant porous layer.” Ex. 1005, 11:1–5. The Petition does not sufficiently explain why such a phase separation structure produced by Nishikawa’s mixed solvent meets claim 10’s recited “uniform coating solution.” Consequently, Petitioner does not present a compelling, meritorious challenge to claim 10 as obvious over Nishikawa’s teachings.” slip op. at 25
