CAFC-PTOMay 14, 2026·25-1470·Affirmed.

Spero v. Mercedes-Benz USA, LLC

Patent Trial and Appeal Board

Holding

The Federal Circuit affirmed, under Fed. Cir. R. 36, the PTAB decisions in two consolidated inter partes reviews (IPR2023-01026 and IPR2023-01027), so the Board's rulings stand and appellant Spero obtained no relief. The judgment gives no reasoning.

Why It Matters

The Rule 36 judgment leaves the Board's decisions in place without explanation, so it offers no guidance on the underlying issues. The result is clear (affirmed, no relief for the appellant), but the patents, claims and grounds are not identified in the judgment.
