How to manage your Registration: Representation

To appoint a person or company as a representative before the International Bureau for one or more international applications or registrations, use form MM12, provide a power of attorney, or simply indicate the representative’s name and address on the form.

To update the contact details of a representative already recorded in the International Register, use form MM10 (change in the name and/or address of the representative).

For further information on representation before the International Bureau, see paragraphs B.I.09.01 to 12.08 of the Guide to the International Registration of Marks under the Madrid Agreement and the Madrid Protocol.
