If you decide you want a European patent, you have a further choice between the direct European route and the Euro-PCT route (see point 8
and Part 2 of
Guide: PCT procedure at the EPO
). With the direct European route, the entire European patent grant procedure is governed by the EPC alone; with the Euro-PCT route, the first phase of the grant procedure (the international phase) is subject to the PCT, while the regional phase before the EPO as designated or elected Office is governed primarily by the EPC.
