  • On May 10, 2013, the United States Court of Appeals for the Federal Circuit (Federal Circuit) issued an opinion that further muddied the waters of Section 101 patent eligibility (35 U.S.C. § 101). In CLS Bank In’tl v. Alice Corp, a majority of the Federal Circuit held that respondent Alice’s method and medium claims were ineligible for a patent. However, the Federal Circuit was split as to whether Alice’s system claims were patent eligible. This case exposed a growing divide among the judges over patent eligibility, manifesting itself in the case’s multiple concurring and dissenting opinions.
