2.4.3 Certificate of exhibition 

As regards the requirements described in A‑IV, 3 ("Display at an exhibition"), for Euro-PCT applications the certificate of exhibition, where relevant, is to be filed within the 31-month time limit for entry into the European phase. If the document is not filed in due time, the applicant is informed of this in a communication under Rule 112(1). The omission may be remedied by a request for further processing, which will be granted if within two months from notification of the communication the certificate is furnished and the fee for further processing is paid (see E‑VIII, 2).
