Are there any restrictions on use of the “®” symbol?

There are three important restrictions on use of the “®” symbol: (1) it may only be used after the mark is registered (you may not use it during the application process); (2) it may only be used on or in connection with the goods and services listed in the federal registration; and (3) it may only be used while the registration is still alive (you may not continue to use it if you don’t maintain the registration or it expires). Note: Because several foreign countries use “®” to indicate that a mark is registered in that country, use of the symbol by the holder of a foreign registration may be proper.
