How to manage your Registration: Change in ownership

To request recording of a total or partial change in ownership, use form MM5.

The International Bureau does not require evidence of the change in ownership and no supporting documents (such as copies of the deed of assignment or other contract) should be sent to the International Bureau.

For further information on changes in ownership, please refer to paragraphs B.II.60.01 to 69.05 of the Guide to the International Registration of Marks under the Madrid Agreement and the Madrid Protocol.
