Where the certified copy of the priority document or, where no copy must be filed (see point 618
), the application number has not yet been submitted on entry into the European phase, the applicant will be invited to furnish that copy or number within two months from the date of a notification under Rule 163(2) EPC
. This time limit cannot be extended. If the priority document or the application number is not submitted within that time limit, the priority right is lost.
