Back to Trademark ownership

Can I add a second owner to an existing trademark?

Senior Trademark Attorney

Yes. A partial assignment can transfer a share of trademark ownership to a new co-owner, converting a sole-owned trademark into a jointly owned one. This requires a signed assignment document and recording with the IP office.

Before adding a co-owner, consider drafting a joint ownership agreement that sets out how decisions will be made, how rights will be enforced, and what happens if one party wants to sell or transfer their interest. These matters are not governed by IP law by default and need to be agreed contractually.
