      “preponderance of evidence that claims 1–4 and 6–17 are unpatentable, but for the reasons expressed below rather than those expressed in our Decision. Additionally, we maintain our prior conclusion that Petitioner has failed to demonstrate that claim 5 is unpatentable without any modification to our reasoning expressed in the Decision. We repeat our prior analysis of claim 5 from our Decision so that this single paper contains the substance of our analysis of all of Petitioner’s challenges to the claims. Accordingly, for the reasons set forth below, we determine that Petitioner has demonstrated by a preponderance of evidence that claims 1–4 and 6–17 are unpatentable but has failed to show that claim 5 is unpatentable.” slip op. at 6

      “evidence quantifying how much additional weight Smith’s container could hold if reinforced as Petitioners proposed,” Opp. 3, we also find it unpersuasive. We determine that Dr. Wooley’s testimony, by itself, supports our conclusion that Smith’s container, as Petitioner proposes to modify and combine it with the other pieces of prior art, would meet the “at least 30,000 pounds” limitation. Ex. 1001 ¶¶ 132–141. In this testimony, Dr. Wooley provided a detailed explanation of how much proppant the modified Smith container could hold. See id. We have reviewed that testimony and agree with Dr. Wooley’s conclusion and reasoning. Thus, we disagree with Patent Owner’s argument that Petitioner has failed to provide “any” evidence to support our conclusion that Smith’s modified container can hold “at least 30,000 pounds” as required by claims 4, 7, 10, 12, 15, 18, and 19.” slip op. at 7

See Final Dec. 33–36, 42–43, 59. We find that the Petitioner has shown all of the limitations of these claims are accounted for in the proposed combinations and that Petitioner has provided an adequate rationale for why a person of ordinary skill would have been motivated to combine the references in the manner proposed with a reasonable expectation of success. See generally Final Dec. (addressing all of Patent Owner’s remaining arguments); Pet. 34–58 (providing mapping for claims 7, 10, 12), 69–70 (claim 15), 79–82 (claims 18 and 19).

      “terminal demand” in a single sentence supported by citations to portions of the Specification and testimony from Dr. Lomp. Id. at 15–16 (citing Ex. 1001, 7:8–11, 18:50–54, 19:1–4, Figure 15A; Ex. 2001 ¶¶ 7, 16, 19–21). Based on our review of the cited portions of the Specification, it is not apparent how those sections support WPI’s proffered meaning of “subscriber terminal demand.” None of the cited portions explicitly defines “subscriber terminal demand” or uses the term, and WPI does not explain why those cited portions are relevant to the inquiry. The cited testimony from Dr. Lomp reflects his opinion but is not supported by any citations to other evidence, including the Specification itself. To the extent that WPI’s argument regarding the meaning of “subscriber terminal demand” relies upon Dr. Lomp’s testimony, we currently find that argument unpersuasive because it is unsupported by other evidence. TCT has not expressly argued the meaning of “subscriber terminal demand” but instead implies a meaning by identifying specific portions of Eizenhöfer that allegedly teach this limitation. Pet. 31–32 (citing Ex. 1004, 3:7–10, Abstract). Absent briefing with citations to relevant evidence, we decline to offer our own express interpretation of “subscriber terminal demand.” Rather, we determine that TCT’s implied interpretation and its argument based on that interpretation demonstrates a reasonable likelihood of establishing that Eizenhöfer describes the recited limitation. Because resolution of the dispute may require an express interpretation of “subscriber terminal demand,” we also direct the parties to address explicitly the meaning of this phrase at trial and cite relevant evidence from among at least other claims, the Specification, and the prosecution history.” slip op. at 4

    • PTAB / AIA Trials › Discretionary denial › §325(d) same art / argumentsDecided for petitioner

      “reasons. First, WPI has failed, as required under Rule 42.71(c), to identify an abuse of discretion stemming from our allegedly “unreasonable” failure to exercise discretion under § 325(d) and deny institution of challenges based on Miller. Second, WPI merely reiterates an argument already considered and rejected, and thus fails to meet its obligation under Rule 42.71(d) to “identify all matters . . . misapprehended or overlooked.” We disagree that WPI offered a “clear comparison” of the entirety of the claims that were allegedly previously considered by the Office during reexamination of the ’326 patent to the claims at issue in this proceeding. Describing claims in the ’326 patent as “closely related” or reciting “similar features” without providing the actual text of those claims fails to provide an adequate basis for comparing those claims to the claims at issue in this proceeding. The paraphrased comparison of claims in the ’326 patent to the claims here is similarly lacking in clarity. Third, even if we were to determine that WPI sufficiently compared the “orthogonal code generator” recited in claims of the ’326 patent to the one recited in the claims at issue, such a comparison fails to demonstrate enough similarity in the claims overall to justify a discretionary denial of TCT’s challenge based on Miller.” slip op. at 9

      “terms, and we agree, for purposes of this decision, that claim 42 does not require a specific quantity of DME in the distillation overhead. We do not agree with Petitioner, however, that the Singh and ’507 patent disclosures are identical with respect to the addition of water to distillation column 22. As indicated in our Decision, both Singh and the ’507 patent describe adding small amounts of water to column 22 for the purpose of inhibiting impurity formation. See Dec. 5–6. The ’507 patent, however, includes additional description of adding water to column 22 for the purpose of producing DME in the distillation overhead. See id. at 7 (citing Ex. 1002, col. 11). This additional description of adding water to produce DME in the distillation overhead does not refer back to the description of adding water as an inhibitor (see Ex. 1002, 10:9–32), or otherwise indicate that the small amounts of water used to inhibit impurity formation in the ’507 patent and Singh processes would produce DME in a distillation overhead. In addition, for the reasons explained in our Decision (Dec. 25–26), Petitioner has not persuaded us that the prosecution history of the ’507 patent includes an admission by Patent Owner that the addition of any amount of water to the distillation step would result in DME in an overhead stream. See Req. Reh’g 10. In sum, Petitioner has not convinced us that our Decision was based on an erroneous claim interpretation or that we overlooked evidence that the addition of any amount of water in the steps common to the Singh and the ’507 patent processes would necessarily result in the presence of DME in a distillation overhead. With respect to Petitioner’s assertions regarding Akinori, we note the Petition relied on Akinori as evidence that DME was necessarily produced in the ’095 patent process. See Pet. 43. Petitioner did not explain how Akinori was relevant to show the presence of DME in the distillation overhead of Singh.

Holdings, summaries, rulings, issues, outcomes, winners and claim constructions shown for a decision were generated by a large language model reading the opinion.
