a trademark marked TM can play a certain protective role. However, if the trademark is not approved and registered by the Trademark Office, its legal protection is not strong. Only when the unregistered trademark reaches a certain popularity can it obtain legal protection to a certain extent.
The circle R is the mark of "registered trademark", which means that the trademark has been registered in the State Trademark Office and passed the examination by the Trademark Office, and has become a registered trademark. A registered trademark has the characteristics of exclusiveness, exclusiveness and uniqueness. It belongs to the owner of the registered trademark and is protected by law. No enterprise or individual may use it without the permission or authorization of the owner of the registered trademark, otherwise it will bear the tort liability. Using TM means trademark symbol, that is, the words, graphics or symbols marked with TM are trademarks, but they are not necessarily registered.
