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 2022 update to the Trademark Assignment Dataset contains detailed information on more than 1.29 million assignments and other transactions recorded at the USPTO between March 1952 and January 2023, involving 2.28 million unique trademark properties (an individual application or registration). 

A working paper describing these data is available at SSRN and as a published version in the Journal of Economics and Management Strategy. Users are requested to cite this documentation when using these data: Graham, SJ, Marco, AC, Myers, AF.
