What happens if the owner of a trademark changes?

When the ownership of a trademark changes, it is essential for the new owner to formally document this change to maintain the validity of the trademark. Therefore, an assignment of ownership must be filed with the USPTO. This legal document records the transfer of rights from the original owner to the new owner. Additionally, change of address forms may also be submitted to update any relevant contact information associated with the trademark.

It is important to note that simply changing ownership does not automatically update the trademark registration, nor does it lead to the trademark being deleted from the registry. New applications are also not necessary for each use of the trademark; once ownership is properly assigned, the trademark can continue to be used under its existing registration. This process ensures that the rights to the trademark are recognized and protected, maintaining the integrity of the trademark registry.
