1.3
Filing of documents subsequent to the application

Documents subsequent to the international application may be filed with the EPO as receiving Office on paper or electronically; see GL/PCT-EPO A-II, 1.2.

In the international phase, priority documents may not be filed with the EPO as receiving Office by fax or electronically; they can, however, be filed with the IB direct using ePCT. Authorisations may not be filed with the EPO as receiving Office by fax or Web-Form Filing.

If a document subsequent to the international application is filed by fax, there is no need to submit a confirmation copy unless the receiving Office invites the applicant to submit one (Form PCT/RO/141). It might do so particularly for substitute sheets under Rule 26 and sheets to be incorporated by reference under Rule 20.6. For such sheets, applicants are therefore advised to submit a confirmation copy on their own initiative directly after sending them by fax. If a confirmation copy is not submitted within the time limit prescribed in the invitation issued by the receiving Office, the document will be treated as not having been received (Form PCT/RO/149).
