6.5 Declaration of priority
An applicant wishing to claim priority must file a declaration of priority indicating:
The declaration of priority shall preferably be made on filing the European patent application (Rule 52(2)). In such a case the declaration of priority, indicating at least the date on which and the country for which the earlier application was filed, should be present in the request for grant form (Rule 41(2)(g)). However, if a priority claim is added or corrected after the request for grant form has been filed (see A‑III, 6.5.1 and A‑III, 6.5.2), the applicant will not be invited by the EPO to file a corrected request for grant.
the requirements of Rule 52(1) are met.
