Where the applicant claims the priority of an earlier application, a certified copy of that earlier application ("the priority document") must be filed with the receiving Office or the International Bureau within 16 months after the priority date. However, if the earlier application was filed with the receiving Office, the applicant may request that the receiving Office transmitstransmit a certified copy of the earlier application to the International Bureau. For that purpose, a check-box is provided in Box No. VI of the PCT request form.
Please note that the procedure whereby the EPO includes, free of charge, a copy of the previous application from which priority is claimed in the file of a European patent application does not apply in respect of an international application processed by the EPO as receiving Office (see point 620621). Moreover, in the case of an EP priority document, the obligation to furnish thesuch a priority document cannot be met by a request to the IB under the Digital Access Service (DAS) to retrieve that documentit from an electronic library, because the EPO does not participate in this system. However, where the earlier application was filed as a national application with a national office that participates in DAS, the IB may be requested to obtain a certified copy of the earlier application from the digital library. For that purpose a check-box and a text field for the required access code are provided in Box No. VI of the PCT request form.
A priority document may not be filed by fax or using the EPO new online filing – case management system (CMS) or the EPO web-form filing serviceA priority document issued in paper form should also be submitted in that form to the EPO to ensure the validity of its certification. For that reason, it may not be filed by fax. On the other hand, priority documents issued in electronic form are accepted only if they are digitally signed by the issuing authority and if that signature is also accepted by the EPO. At present, only the Online Filing software supports the submission of priority documents issued in electronic form (see points 69 and 76).
