Illinois Tool Works, Inc. moves to voluntarily dismiss its appeal, No. 2023-1252, and to dismiss Termax Com- pany’s cross-appeal, No. 2023-1254. Termax opposes dis- missal of its cross-appeal. We grant both motions. *2 Termax appeals from the Patent Trial and Appeal Board’s final written decision in this inter partes review, which agreed with Termax that all challenged claims of Il- linois Tool Works’ U.S. Patent No. 10,683,882 are un- patentable. We have employed the familiar rule that “the prevailing party in a lower tribunal cannot ordinarily seek relief in the appellate court” to appeals from the Board. SkyHawke Techs., LLC v. Deca Int’l Corp. , 828 F.3d 1373, 1375 (Fed. Cir. 2016) (citation omitted). We see nothing that warrants departing from that rule here.

In opposing dismissal, Termax contends that the Board erred in its construction of certain claim limitations that have also been incorporated into Illinois Tool Works’ new patent. Termax hopes that a favorable decision on its claim construction arguments here will collaterally estop Illinois Tool Works from asserting those newly issued claims. But in SkyHawke , we rejected a similar attempt to appeal from a Board’s claim construction when the appellant did “not seek to alter the judgment of the Board.” Id . There, as here, Termax “is merely trying to preempt an unfavorable outcome” as to some other potential proceeding regarding Illinois Tool Works’ new patent “that may or may not arise in the future,” and, if such an outcome does arise, Termax may appeal “at that time.” Id. at 1377.

Accordingly,

I T I S O RDERED T HAT :

(1) The motions are granted, and the appeals are dis- missed. *3 3

(2) Each side shall bear its own costs.
