PER CURIAM. Appellant VirnetX Inc. seeks review of a decision of the Patent Trial and Appeal Board holding that various claims of VirnetX’s U.S. Patent No. 6,502,135 are invalid for obviousness and anticipation. This appeal has been overtaken by events. A decision by this court earlier this year in VirnetX Inc. v. Mangrove Partners Master Fund, Ltd., No. 2020-2271, 2023 WL 2708975 (Fed. Cir. Mar. 30, 2023), upheld the decision of the Board in an inter partes review holding that various claims of the ’135 patent were invalid. VirnetX acknowledges that the Mangrove Partners decision renders moot VirnetX’s arguments as to claims 1, 3–4, and 7–8 of the ’135 patent. Consequently, the only claim of the ’135 patent still at issue in this case at the time of the oral argument was claim 18. And counsel for VirnetX acknowledged that if claim 18 were invalidated in the co-pending case of VirnetX Inc. v. Apple Inc., No. 2022-1523, argued the same day as this case, this case would be entirely moot. We have today affirmed the Board’s decision in the copending Apple appeal. This case is therefore moot, and the appeal will be dismissed. Case: 19-1671 VIRNETX INC. Document: 120 Page: 3 v. CISCO SYSTEMS, INC. Filed: 10/20/2023 3 Because there has been no suggestion that the existence of the unreviewed Board decision in this case will cause unfair prejudice to VirnetX or any other party, we decline to vacate that decision as part of our judgment dismissing this appeal. See U.S. Bancorp Mortg. Co. v. Bonner Mall P’ship, 513 U.S. 18 (1994). In particular, this is not a case in which an appellant has been “frustrated by the vagaries of circumstance” or the “unilateral action” of the appellee such that the appellant “ought not in fairness be forced to acquiesce in the judgment.” Apple Inc. v. Qualcomm Inc., 17 F.4th 1131, 1137 (Fed. Cir. 2021) (quoting Bonner Mall, 513 U.S. at 25); see also LSI Corp. v. U.S. Int’l Trade Comm’n, 604 F. App’x 924, 929 (Fed. Cir. 2015) (The decision whether to vacate a judgment when the case becomes moot by happenstance while on appeal is a matter “not of constitutional necessity but of remedial discretion.”). DISMISSED
