Welcome to the Trademark Electronic Search System (TESS). This search engine allows you to search the USPTO's database of registered trademarks and prior pending applications to find marks that may prevent registration due to a likelihood of confusion refusal.
WARNING: Before conducting your search, you must understand the following: (1) what the database includes; (2) how to construct a complete search; and (3) how to interpret the search results. Click TESS TIPS for detailed information on these and other important search topics.
