1.11 Power of attorney 

Generally, a separate power of attorney must be submitted to either the receiving Office or the International Bureau or, where it appoints an agent to represent an applicant specifically before the ISA, SISA or IPEA, to that Authority.

It must be duly signed and the name and address of the appointed person must comply with Rule 4.4.

However, the EPO in its capacity as receiving Office, ISA, SISA and IPEA has waived the requirement under Rule 90.4(b) that a separate power of attorney be submitted to appoint a (common) agent or a common representative (see GL/PCT‑EPO A‑VIII, 1.13). Thus, in cases where this waiver is applicable, the requirements of signature and proper indication of name and address under Rule 90.4(c) do not apply.
