When must the applicant file a translation of the Euro-PCT application?
Overview
5.5.002If a translation must be filed, the language of the translation determines the language of the proceedings before the EPO (see point 5.1.013). At any time during the processing of the application in the European phase, errors made in the translation may be corrected by bringing the translation into line with the application as filed.
5.5.003If the international application has been published by the IB in an official language of the EPO, no translation is required and any translation that is nevertheless filed will be ignored, since the language of the proceedings may not be changed upon entry into the European phase (see point 5.1.014).
5.5.004In written proceedings the applicant may use any official language of the EPO, but any amendments to the application must always be filed in the language of the proceedings (see point 5.1.013).
5.5.005On the question of whether a translation of the priority document must be submitted, reference is made to points 5.13.013 ff.
