5.4 Missing parts of the description or missing drawings based on the priority application, no change in filing date
5.4.1 Late-filed missing parts when priority is claimed
In the case of a request under Rule 56(3), the EPO checks that the requirements for the priority claim are met (see A‑III, 6).
Where the applicant files a request under Rule 56(3) (see A‑II, 5.4), the priority claim in question must have been in existence no later than on the date on which the requirements laid down in Rule 40(1) were first fulfilled (see A‑II, 4.1).
