Guidelines for Examination in the European Patent Office



November 2018 edition

The Guidelines for Examination give instructions on the practice and procedure to be followed in the various aspects of the examination of European applications and patents in accordance with the European Patent Convention and its Implementing Regulations.

Content description

By decision of the President of the EPO dated 25.07.2018 and pursuant to Article 10(2) EPC, the Guidelines for Examination have been amended. As announced in the Notice from the EPO dated 25.07.2018 (OJ EPO 2018, A73), the new Guidelines apply as from 1 November 2018.

The Guidelines have the following eight-part structure:

  • Part A: Guidelines for Formalities Examination
  • Part B: Guidelines for Search
  • Part C: Guidelines for Procedural Aspects of Substantive Examination
  • Part D: Guidelines for Opposition and Limitation/Revocation Procedures
  • Part E: Guidelines on General Procedural Matters
  • Part F: The European Patent Application
  • Part G: Patentability
  • Part H: Amendments and Corrections

Part A outlines the procedures for formalities examination, mainly with regard to grant proceedings. Part B deals with search matters. Parts C and D relate to procedures to be followed in examination and opposition proceedings, respectively.

Part E summarizes procedural matters relevant to several or all of the stages in proceedings before the EPO. It also contains information about the procedure before the EPO as designated or elected Office, applicable to Euro-PCT applications.

Substantive requirements of the procedures under the EPC are explained in Parts F, G and H:

  • Part F defines the requirements which the application must fulfil other than patentability, in particular unity of invention (Article 82), sufficiency of disclosure (Article 83), clarity (Article 84) and the right to priority (Article 87 to Article 89).
  • Part G deals with the requirements of patentability provided for in Article 52 to Article 57, in particular exclusions from patentability (Article 52(2) and Article 53), novelty (Article 54), inventive step (Article 56) and industrial application (Article 57).
  • Part H deals with the requirements relating to amendments and corrections, in particular to questions of admissibility (Rule 80 and Rule 137) and compliance with Article 123(2) and (3), Rule 139 and Rule 140.

Available formats and amendments

The revised Guidelines for Examination (November 2018) are available online in the EPO's three official languages in both HTML and PDF format. The printed version has been discontinued.

Amendments in the 2018 revision have been made in all eight parts in order to bring the text into line with legal and procedural developments.
