The request for unitary effect must be duly signed. It may be signed by the proprietor, provided that their residence or principal place of business is in an EPC contracting state. Where the request is signed on behalf of a legal person, the signatory's position within that legal entity must also be indicated. The request may also be signed by the representative if one has been appointed (see 2.2.5).
If there is more than one proprietor, each proprietor or their appointed representative must sign the request for unitary effect and, where applicable, the appointment of the common representative. This also applies if one of the proprietors is deemed the common representative (see 2.2.5).
