The U.S. Supreme Court has once again been urged to revisit 35 U.S.C. § 101, the statute governing patent eligibility. Audio Evolution Diagnostics, Inc.

Cir. 2025) — On January 10, 2025, the Federal Circuit reversed the district court’s opinion that claims of a Novartis patent are invalid for lack of adequate written description, but affirmed the district court’s finding that the claims were not proven invalid for lacking enablement or being obvious over the asserted prior art.
