3.4.1 Failure to reply in time or no reply 

If the applicant does not reply within the set time limit to the invitation for informal clarification, the examiner will prepare the search report and WO‑ISA to the extent possible without the requested clarification.

If the applicant replies after the time limit has expired, and the search report has not yet been established, the reply should be taken into account; if the search report has already been established the reply will not be taken into account.
