On June 30, the ninth edition of the Manual of Patent Examining Procedure was revised to include updated information on patent examination policy and procedure related to a number of issues, including subject matter eligibility and examination of computer-implemented functional claim limitations.
The June 2020 revision updates sections of chapters 100-1000, 1200-1500, and 1700-2800. The updated sections have a revision indicator of [R-10.2019], meaning these sections have been updated to reflect USPTO patent practice and relevant case law as of October 31, 2019. In addition, the June 2020 revision updates Chapter FPC - Form Paragraphs Consolidated, the Foreword, the Introduction, the Subject Matter Index, and all Appendices, except Appendix I and Appendix P.
