The demand should indicate the agent or common representative who has been appointed by the applicant(s) or a sub-agent who has been appointed by an agent appointed under Rule 90.1(a) ("the agent for the international phase").[Rule 90; Art. 31(2); Rule 54; ]

Where an agent is appointed, any correspondence intended for the applicant will be sent to the address indicated for the agent.

If there are two or more applicants and no common agent or common representative is appointed, all correspondence will be sent to the first-named applicant who has the right to file an international application with the receiving Office concerned, as this applicant will be considered to be the common representative ("deemed common representative").
