European Patent Convention (EPC 1973)

Rule 100 139 Appointment of a common representative

Art. 59, 133

(1) If there is more than one applicant and the request for the grant of a European patent does not name a common representative, the applicant first named in the request shall be considered to be the common representative. However, if one of the applicants is obliged to appoint a professional representative this representative shall be considered to be the common representative unless the first named applicant has appointed a professional representative. The same shall apply mutatis mutandis to third parties acting in common in filing notice of opposition or intervention and to joint proprietors of a European patent.

(2) If, during the course of proceedings, transfer is made to more than one person, and such persons have not appointed a common representative, paragraph 1 shall apply. If such application is not possible, the European Patent Office shall require such persons to appoint a common representative within two months. If this request is not complied with, the European Patent Office shall appoint the common representative.
