Trademark Assignment Dataset

The USPTO records assignments of trademark applications and registrations to maintain a complete history of claimed interests in a mark. The Office also records supporting documentation for transactions that affect title or otherwise pertain to mark ownership including mergers, name changes, security interest agreements, and licenses. The 2019 update to the Trademark Assignment Dataset contains detailed information on more than 1.06 million assignments and other transactions recorded at the USPTO between 1952 and 2019 and involving 1.96 million unique trademark properties (an individual application or registration).
