Review the linked PDF before publication. The extracted conclusion below is included for audit. VACATED e 2] Case: 26-1525 Document: 13 Page: 2 Filed: 08/12/2026 2 CANADIAN SOLAR, INC. v. MAXEON SOLAR PTE. LTD. shown to be unpatentable. Maxeon now moves to dismiss the appeal as moot in view of its "unilateral covenant not to sue" CSI for infringement. ECF No. 6 at 21. CSI does not oppose dismissal but requests vacatur, which Maxeon opposes. "Vacatur is in order when mootness occurs through . . . the unilateral action of the party who pre- vailed" before the originating tribunal. Arizonans for Off. Eng. v. Arizona, 520 U.S. 43, 71–72 (1997) (cleaned up). Here, CSI's appeal became moot based on Maxeon's unilat- eral actions. We therefore dismiss the appeal as moot and vacate the relevant portion of the Board's decision. We see no need to go further and order the Board to dismiss the petition insofar as it challenged claim 12. See MemoryWeb, LLC v. Samsung Elecs.
