What is a Trademark?

A trademark (or "service mark") is a word, phrase, symbol or design which identifies and distinguishes the source of the goods or services of one party from those of another. There is no requirement that you register a trademark with your state or the USPTO to make a good or service publicly available; however, federal registration has the following benefits: 

  • Constructive notice nationwide of the trademark owner's claim.
  • Evidence of ownership of the trademark.
  • Jurisdiction of federal courts may be invoked.
  • Registration can be used as a basis for obtaining registration in foreign countries.
  • Registration may be filed with U.S. Customs Service to prevent importation of infringing foreign goods.
