Change in Ownership

An international registration may change ownership following an assignment of a mark, merger of one or more companies, a court decision or for other reasons. The change is subject to recording the new owner as the new holder of the registration in question in the international registry.

The change in ownership can only be recorded where the new owner fulfils the necessary conditions to file an international application, namely the person has to be a national of a member of the Madrid Union, or have a real and effective industrial or commercial establishment or is domiciled in such a territory. Furthermore, these conditions need to be fulfilled for each of the members of the Union in which recording of the new holder is requested.

All requests for recording a change in ownership should be submitted, in one copy, on form MM5, in English, French or Spanish.  The form should be submitted to the International Bureau by the holder or through an Intellectual Property Office, in particular through the Office of the assignee as such a request cannot be presented directly to the International Bureau by the new owner.

Detailed information on changes in ownership can be found in paragraphs B.II.59.01-67.05 of the Guide to the International Registration of Marks under the Madrid Agreement and the Madrid Protocol [PDF].
