EPO Rule Changes (April 2010)

Date: 31 March 2010

The European Patent Office has passed certain rule changes.


These changes came into force on 1 April 2010, including:


  • severely limiting the time perious for filing divisional applications;


  • requiring, within a very short time limit, a response to a Search Opinion accompanying a European search report or to a Chapter I report ("IPRP") or Chapter II report ("IPER") drawn up by the EPO against a PCT application; and


  • mandatory election of claims to be searched where there are multiple claims in the same category.
