Each international application has a single filing date. The term "international filing date" should therefore not be interpreted as if there is any further filing date in respect of an international application. The word "international" only refers to the fact that the application concerned was filed as an application under the PCT.
The (international) filing date is not to be confused with the date of entry into the European phase before the EPO or into any national phase before a designated/elected Office (see Annex II). This means that even after entry into the European phase any reference to the filing date of the international application concerned is a reference to the international filing date (see points 447 ff).
