5.1 Late filing of missing drawings or missing parts of the description – on invitation 

The application is examined on filing to check that it is entitled to a date of filing. If, during this check, the EPO notes that parts of the description, or drawings appear to be missing, it shall invite the applicant to file the missing parts within a time limit of two months from the invitation of a communication under Rules 56(1) and Rule 56a(1) (see A‑II, 6). During this time limit, the applicant may proceed under Rule 56 or Rule 56a. If the applicant does not reply to this invitation communication in time, then all references to the missing parts are deemed to be deleted. It is to be noted that the applicant may not invoke the omission of the invitation communication under Rule 56(1) Rules 56(1) and Rule 56a(1).
