Chapter II – General

Overview

5. Time limit 

A revised version of this publication entered into force.

The time limit for establishing the international search report and the WO‑ISA is three months from the receipt of the search copy by the ISA or nine months from the priority date, whichever occurs later. In practice this means that the search and the written opinion should be established no later than 16 months from the priority date.

Rule 42.1, 43bis.1
GL/ISPE 2.13, 16.05
