Euro-PCT Guide: PCT procedure at the EPO
10th edition, January 2017
This guide for applicants is aimed at those interested in pursuing the procedure under the PCT and focuses on elements specific to the PCT procedure before the EPO. It is referred to as the "Euro-PCT Guide" to distinguish it from the PCT Applicant's Guide published by WIPO ("WIPO PCT Guide").
Guide is of a summary nature. It gives an overview of the procedures under the
PCT before the EPO, including entry into the European phase before the EPO as
designated/elected Office. The information it provides is not to be considered
complete, nor is it intended to replace relevant WIPO publications and EPO decisions
and notices concerning specific issues.
The Euro-PCT Guide is based on the information available on 1 January 2017. Any changes to the PCT procedures before the EPO after that date are not reflected in the information provided here. Therefore, in using this Guide, applicants should always verify in particular whether any relevant changes to the procedures have entered into force since 1 January 2017.
Although the information in the Guide is not exhaustive, it aims to cover all the points to note when the EPO acts in its capacity as:
- a receiving Office (RO),
- an International Searching Authority (ISA),
- a Supplementary International Searching Authority (SISA),
- an International Preliminary Examining Authority (IPEA), and/or
- a designated or elected Office.
Any comments on the Euro-PCT Guide may be addressed to Directorate 126.96.36.199, PCT Affairs.
