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.
These Guidelines have been and will be updated at regular intervals to take account of developments in European patent law and practice. Usually, updates only involve amendments to specific sentences or passages on individual pages, in order to bring at least part of the text more closely into line with patent law and EPO practice as these continue to evolve. It follows that no update can ever claim to be complete. Any indication from readers drawing the attention to errors as well as suggestions for improvement are highly appreciated and may be sent by e-mail to:
The Guidelines for Examination in the European Patent Office are also published by the EPO in an electronic, searchable form on the Internet via the EPO website:
