In examination proceedings, the formal requirements of Rules 46 and 49(2)-Rules 49(9) and Rules 49(12) apply equally to application documents submitted during oral proceedings by hand or by email (OJ EPO 2020, A71).
If the applicant is unable to provide formally correct amended application documents during oral proceedings, the following applies:
After the closure of the oral proceedings, the formalities officer on behalf of the examining division (see A‑III, 3.2) will invite the applicant to file formally correct documents within two months. Where the amendments submitted in reply to this invitation differ from the patentable subject-matter established at the oral proceedings, the procedure described in C‑V, 4.7, is to be applied.
