In its most recent decision in Ultramercial, Inc. v. Hulu, the Federal Circuit finally concluded that the claims-at-issue do not cover patent-eligible subject matter under 35 U.S.C. § 101. This comes after two prior decisions by the Federal Circuit reaching the opposite conclusion, and two orders from the U.S. Supreme Court instructing the Federal Circuit to reconsider those two decisions.
Since 2010, the Supreme Court has issued four decisions on patent-eligible subject matter under 35 U.S.C. § 101. In the most recent decision, Alice Corp. v. CLS Bank, the Court continued the restrictive approach set forth in its own precedents in Gottschalk v. Benson, Parker v. Flook, and Diamond v. Diehr, and invalidated patents directed to computerized methods for mitigating settlement risk by using a third-party intermediary. The most significant passage in the Alice decision is that the Court expressly adopted the two-step test it elaborated in Mayo Collaborative Services v. Prometheus Laboratories for all types of patent subject matter issues, including laws of nature, natural phenomena, and abstract ideas.
