ON PETITION ______________________

Before LOURIE, PROST, and WALLACH, Circuit Judges. WALLACH, Circuit Judge. ORDER Centripetal Networks, LLC petitions for a writ of man- damus to direct the Patent Trial and Appeal Board to va- cate all decisions in this inter partes review (“IPR”) and constitute a new panel of administrative patent judges (“APJs”) to reconsider the IPR petition. The United States Patent and Trademark Office (“PTO”), Palo Alto Networks, Inc. (“PAN”), Cisco Systems, Inc., and Keysight Technolo- gies, Inc. oppose. Centripetal replies.

functions, including U.S. Patent No. 9,917,856 (“the ’856 patent”). In 2021, Centripetal filed a civil action against PAN for patent infringement. In response, PAN filed IPR petitions seeking the PTO’s review of Centripetal’s patents. In May 2022, a Board panel consisting of APJs McNamara, Moore, and Amundson, instituted review of the ’856 patent. On June 8, 2022, Centripetal sought rehearing of the institution decision. On June 24, 2022, Cisco and Keysight filed petitions for IPR of the ’856 patent that were substan- tively identical to PAN’s petition and moved for joinder. In December 2022, Centripetal moved for APJ McNamara’s recusal and vacatur of the institution decision on the ground that he owned Cisco stock; Centripetal principally relied on this court’s decision vacating a damages award against Cisco (based on the ’856 patent) after the court con- cluded that disqualification was required under 28 U.S.C. § 455(b)(4) because the spouse of the trial judge owned Cisco stock. See Centripetal Networks, Inc. v. Cisco Sys., Inc., 38 F.4th 1025 (Fed. Cir. 2022). On January 4, 2023, the panel denied Centripetal’s re- quest for rehearing, granted Cisco’s and Keysight’s peti- tions to institute, and joined the three proceedings. APJs McNamara and Amundson then withdrew and were re- placed by APJs Wormmeester and Khan. On February 3, 2023, the new panel rejected Centripetal’s argument that APJ McNamara’s ownership of stock in Cisco required va- catur of the decision instituting PAN’s IPR. The Board con- cluded that “Cisco was not a party to this proceeding at the time of the Institution Decision,” that the statute that re- quired disqualification in Cisco “does not apply to the Board,” and that the value of APJ McNamara’s stock “falls well below” the threshold requiring recusal set by Execu- tive Branch ethical standards. Appx11, Appx20. On February 7, 2023, the Board also denied without prejudice Centripetal’s motion for pro hac vice admission of one of its attorneys based on, inter alia, his prior failure to Case: 23-127 Document: 26 Page: 3 Filed: 05/16/2023

comply with the Board’s rules and procedures and im- proper conduct before two district courts. We have jurisdiction over Centripetal’s mandamus pe- tition under 28 U.S.C. §§ 1295(a)(4)(A), 1651, and 35 U.S.C. §§ 141(c), 319. See Mylan Laby’s Ltd. v. Janssen Pharmaceutica, N.V., 989 F.3d 1375, 1380 (Fed. Cir. 2021). In order for Centripetal to establish entitlement to the “extraordinary remedy” of a writ of mandamus, it must show that: (1) there are “no other adequate means to attain the relief [it] desires,” (2) the “right to issuance of the writ is clear and indisputable,” and (3) “the writ is appropriate under the circumstances.” Cheney v. U.S. Dist. Ct. for D.C., 542 U.S. 367, 380–81 (2004) (internal quotation marks and citations omitted). Centripetal has failed to satisfy this de- manding standard. Centripetal has not shown that it will be unable to raise its arguments after a final written deci- sion, which is expected to issue shortly. Cf. Mobility Workx, LLC v. Unified Pats., LLC, 15 F.4th 1146, 1150–57 (Fed. Cir. 2021) (addressing arguments regarding conflict of in- terest for APJs after final written decision). Nor has it shown any “irremediable interim harm” that would justify mandamus, particularly at this late stage in the proceed- ings. In re Procter & Gamble Co., 749 F.3d 1376, 1379 (Fed. Cir. 2014). Finally, without making any definitive conclu- sions, we cannot say that Centripetal has shown a clear and indisputable right to vacatur, particularly given the lack of any evidence that Cisco was involved in the proceed- ings at the time of institution, Cisco’s backup capacity sta- tus, and the fact that APJ McNamara will not be a member of the panel that decides the ultimate merits in the IPR proceeding.
