“the Board reviews the decision for an abuse of discretion. 37 C.F.R. § 42.71(c). An abuse of discretion may arise if a decision is based on an erroneous interpretation of law, if a factual finding is not supported by substantial evidence, or if an unreasonable judgment is made in weighing relevant factors. Star Fruits S.N.C. v. U.S., 393 F.3d 1277, 1281 (Fed. Cir. 2005); Arnold P’ship v. Dudas, 362 F.3d 1338, 1340 (Fed. Cir. 2004); In re Gartside, 203 F.3d 1305, 1315-16 (Fed. Cir. 2000). The party requesting rehearing has the burden of showing that the decision should be modified, and “[t]he request must specifically identify all matters the party believes the Board misapprehended or overlooked.” 37 C.F.R. § 42.71(d).” slip op. at 2

“Because Petitioner has shown Mr. Cooper’s testimony is supported by underlying factual evidence, and is not based solely on an unsupported assumption and the Miura Declaration, we determine Mr. Cooper’s testimony provides persuasive support for Petitioner’s contention that DME is inherently present in an overhead distillation stream of the ’095 patent process, and that claim 42 is anticipated by the ’095 patent. We have also reviewed the Petition’s analysis of dependent claims 43, 44, 47–51, 53, 55, and 56, and conclude Petitioner has provided sufficient explanation and evidence to support a reasonable likelihood that the additional limitations of these claims are described in the ’095 patent. See Pet. 27–35. In sum, at this stage of the proceeding, Petitioner has established a reasonable likelihood that it would prevail on the merits in showing claims 42–44, 47–51, 53, 55, and 56 are anticipated by the ’095 patent. Therefore, the Request for Rehearing is granted and trial is instituted as to this challenge.” slip op. at 5

“the Petition, and overlooked the fact that Mr. Cooper’s opinion is also based on his own calculations and data in two published articles. See Ex. 1003 ¶ 99. Specifically, Mr. Cooper approximates reactor DME equilibrium concentrations in the ’095 patent examples and explains how these approximations were obtained using readily available data, specifically identifying data in two published articles. Ex. 1003 ¶ 99 (citing Exs. 1029, 1030). Mr. Cooper goes on to explain why, based on the reactor contents and distillation conditions in the ’095 patent examples, DME and acetaldehyde would be present in the overhead distillation streams. Id. ¶¶ 101–102. Because Petitioner has shown Mr. Cooper’s testimony is supported by underlying factual evidence, and is not based solely on an unsupported assumption and the Miura Declaration, we determine Mr. Cooper’s testimony provides persuasive support for Petitioner’s contention that DME is inherently present in an overhead distillation stream of the ’095 patent process, and that claim 42 is anticipated by the ’095 patent. We have also reviewed the Petition’s analysis of dependent claims 43, 44, 47–51, 53, 55, and 56, and conclude Petitioner has provided sufficient explanation and evidence to support a reasonable likelihood that the additional limitations of these claims are described in the ’095 patent.

“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. For the above reasons, the Request for Rehearing is denied as to the challenge based on Singh in view of the ’095 patent and Akinori.” slip op. at 7
