The TM Symbol can generally be used by any person or business to indicate that a particular word, phrase or logo is intended to serve as an identifier for the source of that product or service. You do not have to have registered a trademark to use it and many companies will opt to use the TM symbol for new goods or services in advance of and during the application process.
The R symbol indicates that this word, phrase or logo is a registered trademark for the product or service. It must only be used in the case of registered trademarks and by the owner or licensee. It also must only be used in the regions in which you possess a valid trademark registration.
