Signed authorisation 

Representatives acting before the EPO must on request file a signed authorisation (see A‑VIII, 3.2) within a two-month period specified by the EPO (see E‑VIII, 1.6). If the requirements of Art. 133(2) are not fulfilled, the same period will be specified for the communication of the appointment and, where applicable, for the filing of the authorisation. Professional representatives who identify themselves as such will be required to file a signed authorisation only in certain cases (see the Decision of the President of the EPO dated 12 July 2007, Special edition No. 3, OJ EPO 2007, L.1). However, a legal practitioner entitled to act as a professional representative in accordance with Art. 134(8) or an employee acting for an applicant in accordance with Art. 133(3), first sentence, but who is not a professional representative, must file a signed authorisation; in Euro-PCT proceedings, persons representing clients in these capacities are not required to file signed authorisations if they have already filed an authorisation expressly covering proceedings established by the EPC with the EPO as receiving Office, ISA or IPEA. Where a representative is appointed to act on behalf of the applicant in several of his applications, it is not necessary to file an individual authorisation for each application (see A-VIII, 2.4). A clear indication of the applications concerned is sufficient; the EPO will make sure that a copy of the authorisation is included in all of the files concerned.

The authorisation can also be filed by the applicant. This also applies where the applicant is obliged to be represented, as fulfilling the requirement to be represented is not itself a procedural step under Art. 133(2) to which the rule of obligatory representation applies.

An association of representatives can be authorised to represent a party before the EPO within the meaning of Art. 134(1) (Rule 152(11)). A party appointing several representatives can authorise them collectively as an association instead of having to authorise each of them singly, provided that the association in question is registered with the EPO (OJ EPO 2013, 535).

An authorisation remains in force until its termination is communicated to the EPO. Transfer of representation or termination of authorisation can, subject to certain conditions, be effected electronically by the representative using the MyFiles service (see the Decision of the President of the EPO dated 26 April 2012, OJ EPO 2012, 352). The authorisation will not terminate upon the death of the person who gave it unless the authorisation provides to the contrary.
