Some companies have a lowercase @ or TM or TEL after their names. What does that mean?

In China, TM on trademarks also has its special meaning. In fact, TM logo does not protect trademarks. It is different from R. TM, which means that the trademark has been applied to the State Trademark Office, and the State Trademark Office has issued the Notice of Acceptance, which has entered an objection period, thus preventing others from applying repeatedly. That is to say, existing trademark holders have the priority to use TM, that is to say, words, graphics or symbols marked with TM are trademarks, but they are not necessarily. TM is the abbreviation of English trademark, and tel is the abbreviation of telephone. . . @ is a URL caret. Do you want to say that there is a small R behind the product? Circle R is the mark of "registered trademark", which means that the trademark has applied for registration in the State Trademark Office and passed the examination of the Trademark Office, and has become a registered trademark. R in the circle is the initial letter of English register registration. Registered trademarks have the characteristics of exclusiveness, exclusiveness and uniqueness. It belongs to the registered trademark owner and is protected by law. Without the permission or authorization of the registered trademark owner, no enterprise or individual may use it, otherwise it will bear tort liability. I hope it helps you!
