Patents and Trademarks

Trademark search

Before applying for a U.S. trademark registration, you should search the USPTO's trademark database  TESS (Trademark Electronic Search System) to see if any trademark has already been registered or applied for. You want to check their similarity to your trademark, whether they are used on related products or for related services, and also if they are still live.
