2014 Interim Guidance on Subject Matter Eligibility

The 2014 Interim Guidance on Patent Subject Matter Eligibility (2014 IEG) is for USPTO personnel to use when determining subject matter eligibility under 35 U.S.C. 101 in view of recent decisions by the U.S. Supreme Court, including Alice Corp., Myriad, and Mayo. The 2014 IEG supplements the June 25, 2014 Preliminary Examination Instructions issued in view of Alice Corp. and supersedes the March 4, 2014 Procedure for Subject Matter Eligibility Analysis of Claims Reciting or Involving Laws of Nature/Natural Principles, Natural Phenomena, and/or Natural Products issued in view of Mayo and Myriad.

The July 2015 Update: Subject Matter Eligibility updates the 2014 IEG in response to public comments on the 2014 IEG.  The July 2015 Update includes a new set of examples and discussion of various issues raised by the public comments, and is intended to assist examiners in applying the 2014 IEG during the patent examination process.

The May 2016 Subject Matter Eligibility Update provides (i) a memorandum to the examining corps on best practices in formulating a subject matter eligibility rejection and evaluating the applicant’s response, (ii) additional subject matter eligibility examples in the life science area, and (iii) an open-ended comment period to allow ongoing comments on subject matter eligibility topics. The May 2016 Subject Matter Eligibility Update also announces the selection of subject matter eligibility rejections as a new case study under the Topic Submission for Case Studies Pilot Program.



The USPTO is interested in receiving public feedback on the May 2016 Subject Matter Eligibility Update, including the life sciences examples.
