1.6 Address for correspondence 

Where no agent or common representative is appointed, any correspondence is sent to the address, indicated in Box No. II or III of the PCT request form, of the applicant (if there is only one applicant) or of the deemed common representative (if there are two or more applicants). However, if the applicant wishes correspondence to be sent to a different address, that address must be indicated in Box No. IV instead of the indication of an agent or common representative. In this case, and only in this case, the last check box of Box No. IV must be marked (that is, the last check box must not be marked if either of the check boxes "agent" or "common representative" in Box No. IV has been marked). For proceedings in the international phase before the EPO as receiving Office, International Searching Authority, Supplementary International Searching Authority or International Preliminary Examining Authority, the address for correspondence given may be that of any person in any country.
