Before M OORE, Chief Judge, P ROST and CUNNINGHAM ,
Circuit Judges.
MOORE, Chief Judge.
Yechezkal Evan Spero appeals final written decisions
of the Patent Trial and Appeal Board (Board) determining
claims 1–28, 30–68, and 70 of U.S. Patent No. 10,894,503
are unpatentable. Because we affirm the Board’s decisions
determining the appealed claims of the ’503 patent are un-
patentable in Spero v. Mercedes-Benz USA, LLC, No. 2025-
1470 (Fed. Cir. May 14, 2026), and Spero otherwise failed
to appeal the remaining claims the Board determined are
unpatentable, we dismiss this appeal as moot.
DISMISSED
COSTS
No costs.
