Businesses may only use the ® symbol if they have registered a trademark or service mark with the U.S. Patent & Trademark Office (USPTO). State and local laws govern use of the TM (trademark) and SM (service mark) symbols. Companies may use these two symbols without registering a mark at the federal level.
