More specifically, amended Rule 69.1(a) states that the IPEA will, by default, start international examination when it is in possession of all of i) the demand, ii) the examination fees and iii) either the ISR (or declaration under PCT Article 17(2), and the written opinion.
Applicant can expressly request that examination be postponed until after the expiration of the time limit for filing the demand set forth in PCT Rule 54bis1.
