Searching Marks in USPTO Database

You may conduct a search online for free via our TESS (Trademark Electronic Search System) database. 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.

For more information about conducting a clearance search, please watch the news broadcast-style video titled “Searching” (video #3 in the Trademark Information Network (TMIN) series).

If your mark includes a design element, you will need to search it by using a design code. To locate the proper design code(s), please consult the Design Search Code Manual. NOTE: The USPTO is NOT able to conduct a search for you or provide legal advice concerning what would be a proper search.

If your search in TESS yields a mark that you think might conflict with your mark, make sure that the "Live/Dead Indicator" shows the mark to be "live." A "dead" mark could not be used to block your application.
