Trademark Search

U.S. trademarks can be researched using the web database called Trademark Electronic Search System (TESS). TESS is a Web-based trademark database equivalent to X-Search, the USPTO’s in-house trademark database. No matter how your search goes, keep in mind that trade and service mark registration is a legal procedure and should be done in conjunction with an attorney specializing in trademark law.
