| Trademarks > Trademark Electronic Search System (TESS) |
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.

Access to TESS: TESS is intended for use by the general public. Due to limitations of equipment and bandwidth, TESS is not intended to be a source for bulk downloads of USPTO data. Bulk data may be purchased from USPTO at cost (see the USPTO Products and Services Catalog). Individuals, companies, IP addresses, or blocks of IP addresses who, in effect, deny service to the general public by generating unusually high numbers of daily TESS accesses (searches, pages, or hits), whether generated manually or in an automated fashion, may be denied access to these servers without notice. On Monday through Saturday, TESS will not be available for one hour from 4:00 to 5:00AM (EST) for database update.
TESS Assistance: Please do NOT contact the Trademark Assistance Center for assistance in constructing or executing searches on TESS. If you have thoroughly reviewed the TESS online help (accessed through HELP link, above) and still have a question (or comment or suggestion), you may e-mail TESS@uspto.gov. While we cannot promise to answer all messages, your feedback will be considered and may lead to future improvements on TESS.
