This updated 14th (October 2013) edition of the first part of the Guide is based on the revised European Patent Convention (EPC 2000) which entered into force on 13 December 2007. All references to articles or rules in this Guide therefore relate to the EPC as in force since that date. Please note, however, that in some cases certain provisions of the earlier Convention (EPC 1973) will continue to apply for applications which were pending at the time the revised EPC entered into force. The present edition is updated to 1 October 2013, and only takes account of changes to European Patent Office (EPO) procedures entering into force up to that date. Users of this Guide should therefore always check the EPO website (www.epo.org
) for information about any changes which may have occurred since then.
