Appointment of an agent, common agent or common representative for the international phase requires a declaration to that effect to be made either in the PCT request (Box No. IV PCT request form) itself or in a separate notice ("power of attorney"). For this purpose the "PCT/Model of power of attorney" may be used, which is available on the WIPO website.[ 20 ] If the agent, common agent or common representative is at the same time to be appointed for the procedure in the European phase, applicants are referred to the information in points 113 ff.
For the appointment of the agent, the common agent or the common representative to be effective, the PCT request or the power of attorney must be duly signed by (all) the applicant(s) for whom the agent, the common agent or the common representative is intended to act (see points 161 ff).
Please note that a power of attorney may not be filed by fax (see point 69).
