GL-PCT FOREWORD 1 Preliminary remarks

As repeatedly requested by users since the removal of the part of the EP Guidelines that dealt with the EPO as PCT Authority, the EPO in the present Guidelines is publishing the specific procedures and substantive issues before the EPO as RO/(S)ISA/IPEA which until now were contained mainly in internal instructions, in as far as they are relevant for the public.
These Guidelines can be used and referred to by examiners and formalities officers, as well as patent attorneys, in addition to the existing Euro-PCT Guide ("PCT procedure at the EPO, Guide for applicants") and the PCT ISPE (International Search and Preliminary Examination) Guidelines. They are complementary to, but not a substitute for, the ISPE and RO (Receiving Office) Guidelines, as well as the PCT Applicant's Guide ("WIPO PCT Guide"), all published by WIPO. They will exist in parallel with the Euro-PCT Guide ("PCT procedure at the EPO, [International phase and entry into the European phase], Guide for Applicants"), which has the status of a Notice from the EPO.
Their full name is "Guidelines for Search and Examination at the European Patent Office as PCT Authority", or "PCT-EPO Guidelines" for short, and throughout these Guidelines they are referred to as "GL/PCT-EPO".
The PCT-EPO Guidelines are published as a standalone document in electronic format only, and will be revised on a yearly basis in autumn at the same time as the revision of the EP Guidelines. The electronic publication includes not only the online version in HTML format, but also a printable file.
This first version of the PCT-EPO Guidelines is intended to contain at least those parts of existing internal instructions for examiners and formalities officers which are considered appropriate for publication. It should therefore not be expected to be as complete as the EP Guidelines. The aim is to gradually expand the document with each revision cycle.
Any indication from readers drawing attention to errors as well as suggestions for improvement are highly appreciated and may be sent by email to Directorate 5.2.2, International Legal Affairs, PCT, at
