CAFC-PTOMay 14, 2026·25-1028·Dismissed as moot.

Spero v. Volkswagen Group of America, Inc.

Patent Trial and Appeal Board

Holding

The Federal Circuit dismissed Spero's appeal from the Board's final written decision holding claims 1–8, 10–19, 21–30, and 32–33 of the '029 patent unpatentable as moot. It did so because it affirmed the Board's unpatentability determination for all claims of the '029 patent in a companion appeal, Spero v. Mercedes-Benz USA, LLC, No. 2025-1306, decided the same day.

Why It Matters

When a companion appeal already affirms unpatentability of every claim of a patent, parallel appeals from other IPRs on that patent may be dismissed as moot without any merits analysis, so the companion appeal is the one to watch.
