6.4.1 Later-filed correct application documents or parts when priority is claimed 

In the case of a request under Rule 56a(4), the EPO will check that the requirements for the priority claim are met (see A‑III, 6).

Where the applicant files a request under Rule 56a(4) (see A‑II, 6.4), the priority claim in question must have been in existence on the date on which the requirements laid down in Rule 40(1) were fulfilled (see A‑II, 4.1).

The requirement that the correct application documents or parts be completely contained in the priority application is the same as for missing parts of the description or missing drawings filed under Rule 56(3) (see A‑II, 5.4.2).

Final assessment of the "completely contained" requirement falls under the responsibility of the examining division (see C‑III, 1).
