This updated 20th (October 2020) edition of the Guide is based on the revised European Patent Convention (EPC 2000) which entered into force on 13 December 2007. All references to articles or rules in the Guide therefore relate to the EPC as in force since that date. The Guide cannot go into the details or specific issues of the European patent grant procedure, and it does not constitute an official commentary on the European Patent Convention (EPC).
If you need more detailed information, you are advised to consult the Guidelines for Examination in the European Patent Office, a comprehensive guide to every stage of the grant procedure and to EPO practice.
