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.
