Guide for applicants, Part 2: PCT procedure before the EPO (Euro-PCT Guide)

If no agent has been appointed, any correspondence is sent to the applicant. In that case applicant firms with operations at different locations may indicate an address for correspondence in an EPC contracting state. Since taking care of the post of another person requires competence to represent that person, the address of a third party may not be indicated, but only an address of the applicant himself.
