The EPO as receiving Office (and also as ISA, SISA and IPEA) has waived the requirement that,
for the effective appointment of an agent, common agent or common representative,
a signed separate
power of attorney must
be submitted to it if the PCT request is not signed by (all) the applicant(s). The waiver does not apply to a legal practitioner referred to in Article 134(8) EPC
if that person is not also a professional representative.
