TM on a trademark also has its special meaning. In fact, TM logo does not protect the trademark. It is different from R. TM means that the trademark has been applied to the State Trademark Office, and the State Trademark Office has issued a Notice of Acceptance, which has entered an objection period. This can prevent others from filing repeated applications, and also means that the existing trademark holders have the priority to use it.

circled r is the mark of "registered trademark", which means that the trademark has been applied for registration in the State Trademark Office and passed the examination by the Trademark Office, and has become a registered trademark. R in the circle is the initial letter of English register registration.

a registered trademark has the characteristics of exclusiveness, exclusivity and uniqueness, which 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 tort liability.

TM means trademark symbol, that is, words, graphics or symbols marked with TM are trademarks, but they may not be registered (unregistered ones are not protected by law). TM is the abbreviation of English trademark.
