Starting in 2014, we’ve issued guidance explaining how our patent examiners should evaluate claims for patent subject matter eligibility under 35 U.S.C. 101. This guidance was in response to decisions from the U.S. Supreme Court on claims reciting judicial exceptions including abstract ideas, laws of nature, and natural phenomena, as well as feedback received from the public. Since then, we have issued several supplements to this guidance based on judicial decisions and public feedback.
- The 2014 interim guidance on patent subject matter eligibility (2014 IEG) sets forth a two-part analysis for claims reciting judicial exceptions in view of recent decisions by the U.S. Supreme Court and the U.S. Court of Appeals for the Federal Circuit.
- The July 2015 update on subject matter eligibility updates the 2014 IEG. It reflects public comments and assists examiners when applying the 2014 IEG during the patent examination process.
- The May 2016 subject matter eligibility update provides information to the examining corps on best practices for formulating a subject matter eligibility rejection and evaluating the applicant’s response.
- Memoranda discussing subject matter eligibility decisions from the U.S. Court of Appeals for the Federal Circuit:
- Enfish, LLC v. Microsoft Corp. and TLI Communications LLC v. A.V. Automotive, LLC (May 19, 2016)
- Rapid Litigation Management v. CellzDirect and Sequenom v. Ariosa (July 14, 2016)
- McRO, Inc. dba Planet Blue v. Bandai Namco Games America Inc. and BASCOM Global Internet Services v. AT&T Mobility LLC (November 2, 2016)
- Manual of Patent Examination Procedure (MPEP) Sections 2103, 2104, 2105 and 2106
