The Trademark Application and Registration Retrieval (TARR) system is the U.S. Patent & Trademark Office’s database for controlling federal trademark applications & registrations. The TARR system provides the public online capability to search for available trademarks or to check the status of registered trademarks & pending trademark applications. Information about a specific mark can be found by running a standard Boolean search, or specific searches for marks, serial numbers, registrations, or even as to specific information about a specific mark.
