3.2 The procedure before the EPO as ISA
3.2.6.Correct elements or parts notified after the start of the search and additional fee
3.2.022The receiving Office may notify the ISA of a correct element or part after the ISA has begun to draw up the international search report. In such cases, the EPO as ISA will invite the applicant (Form PCT/ISA/208) to pay an additional fee equal to the search fee within one month of the date of the invitation.
3.2.023If the EPO as ISA is notified of a correct element or part after the search has started but before its completion and the additional fee is paid, it will also complete the already initiated search and issue a non-official international search report and written opinion based on the international application as initially submitted. However, the non-official international search report and written opinion are issued only for the benefit of the applicant and any designated Offices which have filed a notification of incompatibility under Rule 20.8(b-bis) PCT. They therefore do not constitute the international search report under Rule 43 PCT and written opinion under Rule 43bis PCT.
