Résumé

To provide updates to patent examination policy and procedures in a single source, which will improve access to essential guidance for all stakeholders and help to ensure issuance of robust and reliable patents that promote and protect innovation, the United States Patent and Trademark Office (USPTO or Office) issued a revision of the Ninth Edition of the Manual of Patent Examining Procedure (MPEP), published in November 2024 (January 2024 revision). The MPEP provides patent examiners and the public with a reference work on the practices and procedures relative to the prosecution of patent applications and other proceedings before the USPTO. The MPEP contains instructions to examiners, as well as other material in the nature of information and interpretation, and outlines the current procedures that examiners are required or authorized to follow in appropriate cases in the normal examination of patent applications and during other Office proceedings.
