If the applicant has claimed the right of priority of one or more previous applications, he must on entry into the European phase file the results of any search carried out by or on behalf of the office(s) of first filing (OFF) for each application whose priority is claimed.  

No action is required on the part of the applicant where an exemption applies. Firstly, this is the case if the EPO is the authority that performed the search on a claimed priority application and established a search report of one of the following types: a European search report, an ISR, an international-type search report or a search report on a national application drawn up on behalf of a national office. 

If the search results regarding any claimed priority application have to be filed with the EPO but are not received, the applicant will be invited to file, within a period of two months set in the invitation, the copy of the missing search results and/or a statement that these results are (in whole or in part) not available to him. The invitation will be issued at the time the examining division assumes responsibility for the application.
