An applicant may file an international application for which the EPO is a designated Office (and optionally an elected Office). Such an application, once it has been accorded an international filing date, is equivalent to a regular European application and is generally referred to as a Euro-PCT application (
Art. 153(2) EPC). Once the Euro-PCT application enters the regional phase before the EPO the appeal procedures provided for under the EPC supplement the provisions of the PCT (
J 20/89, OJ 1991, 375).
