You can search all registered trademarks free of charge on the U.S. Patent and Trademark Office (USPTO) website using TESS (Trademark Electronic Search System). If your mark includes a design element, you will have to search it by using a design code. To locate the proper design code(s), please consult the Design Search Code Manual, which is here.

You may also conduct a trademark search by visiting the Trademark Public Search Library, between 8 a.m. and 8 p.m. (research assistance is offered between the hours of 8 a.m. and 5 p.m.) at Public Search Facility - Madison East, 1st Floor; 600 Dulany St.; Alexandria, VA 22313. Use of the Public Search Library is free to the public. You can also conduct a search at a Patent and Trademark Depository Library near you.

Private trademark search firms will conduct searches for a fee. The USPTO cannot aid in the selection of a search firm. Search firms are often listed in the yellow page section of telephone directories under the heading "Trademark Search Services" or "Patent and Trademark Search Services."
