In accordance with Art. 10(2)(a) of the European Patent Convention (EPC), the President of the European Patent Office (EPO) had adopted, effective as at 1 June 1978, the Guidelines for Examination in the European Patent Office.

It follows that no update can ever claim to be complete. Any indication from readers drawing attention to errors as well as suggestions for improvement are highly appreciated and may be sent by email to: firstname.lastname@example.org
The binding version of the Guidelines for Examination in the European Patent Office is published by the EPO in searchable HTML format on the internet at .

In the HTML publication, modifications can be viewed by ticking the "Show modifications" box in the upper right corner, which displays inserted text with a green background and deleted text in red strikethrough font. For sections in which no changes have been made, the tick box is greyed out.
