3.6 Re-establishment of rights in respect of the priority period 

Applicants may file a request for re-establishment of rights in respect of the priority period under Art. 122 (see A‑III, 6.6). Any request for re-establishment of rights in respect of the period specified in Art. 87(1) must be filed within two months of expiry of that period, according to Rule 136(1), second sentence. Where a request for re-establishment in respect of the priority period has been allowed, the examining division carefully reviews the relevance of prior-art documents cited previously in the search report or communications.
