"r" is the abbreviation of English "Register". R plus a circle is the mark of "registered trademark", which means that the trademark has been registered in the State Trademark Office and has been examined and approved by the Trademark Office, and has become a registered trademark. The registered trademark "R" has the characteristics of exclusiveness, exclusiveness and uniqueness, and belongs to the owner of the registered trademark, which 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 tort liability.

and "TM" means trademark symbol, that is, the words, figures or symbols marked with TM are only trademarks, but they are not necessarily registered (unregistered ones are not protected by law). "TM" means that the trademark has been applied to the State Trademark Office, and the State Trademark Office has also issued the Notice of Acceptance of Trademark Registration, that is, the Notice of Acceptance of Trademark Registration is the premise of using the "TM" logo. In fact, the law of our country clearly stipulates the use of "R", but it does not stipulate the use and management of TM. As long as the operator wants to inform others that a logo is used as a trademark, he can use the "TM" logo regardless of whether the logo applies for trademark registration.
