Any priority document (i.e. the certified copy of the European application together with the certificate stating the date of filing thereof) will only be issued to the (original) applicant or his successor in title. In the case of applications filed in a language other than an official language of the EPO (Art. 14(2)), the priority document relates to the application as originally filed, not to the translation in one of the official languages of the EPO.
The President of the EPO determines all necessary arrangements, including the form of the priority document and the circumstances in which an administrative fee is payable.
