Patent Eligibility After Alice: Strategies for Protecting Software and Business Method Innovations
More than a decade after the Supreme Court's decision in Alice Corp. v. CLS Bank, software and business method patents still face a brutal invalidity rate under 35 U.S.C. Section 101. Yet meaningful patent protection for software, fintech, cybersecurity, and AI innovations remains achievable for those who understand the rules. This guide walks through the Alice/Mayo two-step framework and its statutory and historical roots (Chakrabarty, Diehr, Bilski, Mayo), the Federal Circuit guideposts that mark the narrow path to eligibility (Enfish, DDR Holdings, McRO, BASCOM, Finjan, and the factual twist of Berkheimer), and the USPTO's evolving examination guidance, including the 2019 Patent Eligibility Guidance, the 2024 AI update, and the precedential Desjardins decision. It then turns practical: claim-drafting and prosecution strategies grounded in labeled hypotheticals, a layered-protection portfolio plan that pairs patents with trade secrets, copyright, and design patents, the status of Section 101 reform through PERA, and a working checklist. The goal is to give judges, practitioners, and inventors alike a clear, usable map of where claims live and where they die.
