Frequently Asked Questions

What is a patent assignment? It is a recorded transfer of patent ownership or rights — an assignment, merger, security interest (lien) or name change — filed with the USPTO. Each is identified by a reel and frame number.

Do I get the new owner's address? Yes. With details enabled, each record includes the assignee's company name and full mailing address, plus every assigned patent and application number.

Can I find every assignment for a company? Yes. Search by assignee name to find where a company acquired rights, or by assignor name to find what it sold or pledged.

How fresh is the data? Every record is read live at run time, so it reflects the register at the moment of the run (see observedAt).
