Legal Term Highlighted
trademark registration: Federal registration of a mark with the U.S. Patent and Trademark Office (PTO) requires that the mark be used in commerce and the filing of a registration application. Once a mark is registered, the owner should always place the trademark registration symbol (®) or "Reg. U.S. Pat. Off." next to the mark. Without this designation, it may be hard to collect damages from one who infringes the mark.
