“from his Declaration cited on page 17 of the Petition, however, Dr. Harwell essentially repeats verbatim the conclusions from the Petition quoted above: 98. As such, Ayers discloses that subterraneous formations of metal-polymer complexes may result due to previous injections of fracturing fluid. For example, fracturing fluid containing polyacrylamide, a common polymer additive to fracturing fluid, may intrude the natural formation and have negative interactions in the way of forming a metal-polymer complex with metal ions naturally present in the formation. Harwell Decl. ¶ 98, cited at Pet. 17. Dr. Harwell provides no additional scientific or technical basis for these conclusory restatements of Petitioner’s assertions, and we find Dr. Harwell’s testimony on this issue entitled to little weight.

We also view Petitioner’s and Dr. Harwell’s conclusions as lacking because they fail to demonstrate that a “subterranean-formed metal-polymer complex” would necessarily have been present in Ayers’s subterranean formations. Instead, as noted by Patent Owner, both Petitioner and Dr. Harwell can muster only that “subterraneous formations of metal-polymer complexes may result due to previous injections of fracturing fluid” and that “fracturing fluid containing polyacrylamide . . . may intrude the natural formation and have negative interactions in the way of forming a metal-polymer complex . . . .” Pet. 17; Harwell Decl. ¶ 98 (emphasis added); see Prelim.

“currently scheduled to begin on January 14, 2025. Prelim. Resp. 55 (citing Ex. 2003 (Specialized Scheduling Order in the Parallel Litigation) at 2). Based on the date of issuance of this Decision, the beginning of the trial in the Parallel Litigation is over eight months before any final decision would have been due had inter partes review been instituted. This large length of time from the trial in the Parallel Litigation to the due date of the final decision in this proceeding weighs strongly in favor of discretionary denial. As stated in the Guidance Memo, “when considering the proximity of the district court’s trial date to the date when the PTAB final written decision will be due, the PTAB will consider the median time from filing to disposition of the civil trial for the district in which the parallel litigation resides.” Guidance Memo 3. Patent Owner provides median time-to-trial statistics for the Oklahoma District Court, which predict a trial date approximately 26.9 months after the Parallel Litigation’s filing date of April 13, 2023. See Prelim. Resp. 56 (citing Ex. 2005 at 2). Because the predicted trial date—approximately July 17, 2025—still precedes by two months the due date of any final decision had inter partes review been instituted, the statistics provided also weigh in favor of denial of institution. Given the proximity of the current trial date—less than four months from the date of this Decision—and the lack of any indication from the parties that the trial date will not hold or that either party seeks a later trial date, we view this factor as strongly favoring discretionary denial.” slip op. at 10

“First, we believe that the Fintiv analysis and factors are a poor fit to the circumstances of this proceeding.10 The Fintiv factors are “related to a parallel, co-pending proceeding” in a district court involving the same patent challenged before the Board. See Fintiv 5 (Heading B) (capitalization omitted). Here, the District Court found the challenged patent to be invalid on a basis that we cannot consider—subject matter eligibility under 35 U.S.C. § 101. See 35 U.S.C. § 311(b) (“A petitioner in an inter partes review may request to cancel as unpatentable 1 or more claims of a patent only on a ground that could be raised under section 102 or 103 and only on the basis of prior art consisting of patents or printed publications.”). There is no parallel consideration by a district court of the invalidity of the challenged claims of the ’602 patent under 35 U.S.C. §§102 or 103. Second, even if we consider the Fintiv factors, we disagree with Petitioner and determine that, under the circumstances presented here, these factors support our denying institution.
