Federal Circuit Further Defines Eligibility Standard for Composition Patent

Feb 13, 2025

In US Synthetic Corp. v. ITC, the Federal Circuit issued a precedential decision providing useful guidance on the application of 35 U.S.C. § 101, which governs patent eligibility. Specifically, the court addressed whether the claims of U.S. Patent No. 10,508,502 (the ’502 patent) were directed to an abstract idea and thus ineligible for patent protection. The case offers valuable clarification on how to assess claims involving physical compositions of matter under the two-step framework established by the Supreme Court in Alice Corp. v. CLS Bank International.
