Following the signature of the Agreement on the establishment of the European Unified Patent Court (UPC) in February 2013, a public consultation on the draft Rules of Procedure began on 25 June. Interested parties now have until 1 October 2013 to submit written comments on the draft Rules of Procedure. The UPC will potentially affect the enforcement of all current European Patents and all future applications. Holders of European Patents need to be aware of the proposals for the new court, in particular the ability to ‘opt-out’ of the UPC’s jurisdiction.
