      “In an [inter partes review], the petitioner has the burden from the onset to show with particularity why the patent it challenges is unpatentable.” Harmonic Inc. v. Avid Tech., Inc., 815 F.3d 1356, 1363 (Fed. Cir. 2016) (citing 35 U.S.C. § 312(a)(3)); see also Intelligent Bio-Sys., 821 F.3d at 1369. This burden of persuasion never shifts to Patent Owner. See Dynamic Drinkware, LLC v. Nat’l Graphics, Inc., 800 F.3d 1375, 1378 (Fed. Cir. 2015) (discussing the burden of proof in inter partes review). Therefore, to prevail in an inter partes review, Petitioner must explain how the proposed combination of prior art would have rendered the challenged claims unpatentable. At this preliminary stage, we determine whether the information presented in the Petition shows there is a reasonable likelihood that Petitioner would prevail in establishing that at least one of the challenged claims would have been obvious over the proposed combinations of prior art. slip op. at 10

      “Petitioner cites to Dr. Hopkins’ Declaration, which repeats nearly verbatim the contentions in the Petition, and then adds testimony that “[t]he resonant period and frequency is what the ’481 Patent refers to as the ‘standard’ operating period and frequency.” Pet. 32 (citing Ex. 1003 ¶ 81). Dr. Hopkins, however, does not provide any citation to the ’481 patent to support this testimony, nor any further explanation as to how or why the resonant period and frequency teaches the “standard operating period and frequency” recited in limitation 1[c]. Therefore, “the cited declaration testimony is conclusory and unsupported, adds little to the conclusory 17 As discussed below, Petitioner also relies on this theory for all of the remaining six challenges in the Petition, and does not provide further explanation in any of those challenges. Accordingly, as explained below, each of Petitioner’s remaining challenges is insufficient for the same reasons described here. assertion for which it is offered to support, and is entitled to little weight.” Xerox Corp. v.

On this record, we find that the annotated excerpt of Chung’s Figure 2 is inconclusive as to whether dovetail (32) (blue) is longitudinally spaced from the expansion portion (yellow). Based on the excerpt of Chung’s Figure 2, it is equally likely that the structures colored blue and yellow terminate in the same plane, as shown in Patent Owner’s annotated excerpt of Chung’s Figure 2, reproduced below: Prelim. Resp. 45–46. In Patent Owner’s annotated excerpt of Chung’s Figure 2 reproduced above, Patent Owner demonstrates that Chung’s dovetail (32) longitudinally terminates in the same plane as the ramped surfaces that flank the dovetail (shown by the orange arrows), and does not appear to be longitudinally spaced past the plane where the expansion portion terminates. See id. (citing Ex. 1005, 10; Ex. 2001 (Culbert Decl.) ¶ 85). On this record, we find Patent Owner’s interpretation of Chung Figure 2 more plausible than Petitioner’s.” slip op. at 19

Petitioner represents that the material it seeks to seal contains its trade secrets. Id. at 2–3. Petitioner filed a proposed protective order, which includes modifications to the Board’s default protective order. See Ex. 1018; Ex. 1019. Patent Owner filed a Response to Petitioner’s Motion. Paper 7. Patent Owner indicates that it does not oppose “the Board sealing Petitioner’s confidential information,” but does oppose Petitioner’s proposed protective order. Id. at 1 (citing Ex. 1018; Ex. 1019). However, Patent Owner represents that “the parties have conferred and agree to the terms of the stipulated protective order filed as Exhibit 2100.” Id.; see also Ex. 2101 (redline comparison of Ex. 2100 to the Board’s default protective order).

Pet. 5, 32–100. Petitioner argues that the asserted references are prior art because the claims of the ’638 patent are not entitled to a priority date earlier than July 28, 2017. Id. at 4–5, 11–29. Patent Owner contends that Petitioner fails to establish a reasonable likelihood of success because Petitioner fails to sufficiently show that the asserted references qualify as prior art. Prelim.

      “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
