If you completed a trademark assignment, a change of ownership will occur, either manually by the new owner, or by the Assignment Recordation Branch. Some assignments processed by the Assignment Branch are automatically updated with the change of ownership, but not all fall under this umbrella, so you should always check to see if yours has been updated. If it has not been automatically updated, you can email the Trademark Operation and inform them of the change of ownership.
