5.1 When can a summons to oral proceedings be issued in substantive examination?

At the beginning of substantive examination, if the examining division is of the opinion that the application cannot be granted directly, at least one substantive communication within the meaning of Art. 94(3) will generally be sent before the division issues a summons to oral proceedings (see C‑III, 4).

In particular, neither the search opinion of an EESR or a supplementary search (ESOP) nor an opinion or report from the PCT procedure (WO-ISA, SISR, IPRP or IPER) is a communication under Art. 94(3), so even if the applicant has replied to them, it is not generally appropriate to send a summons as a first communication in European substantive examination.

Nor are the following communications/requests considered as substantive communications from the examining division for this purpose: invitation under Rule 62a or Rule 63, communication under Rule 137(4), request under Rule 53(3), request under Art. 124 and Rule 141, invitation under Rule 164(2)(a).

Exceptionally, a summons to oral proceedings may be issued as the first action in examination proceedings, provided that the criteria set out in C‑III, 5 are met.

In examination proceedings, where the applicant has been invited to provide a translation of the priority according to Rule 53(3) (see A‑III, 6.8.2 and F‑VI, 3.4), no summons to oral proceedings will be issued until either the translation is provided or the period for further processing in respect of the time limit according to Rule 53(3) has expired.
