A standard for the use of registered trademarks

Second, the subject of trademark use must be legal; second, the trademark used must be legal;

Third, the name and scope of the goods or services using the trademark must be legal.

the absence of any one of the elements constitutes the nonstandard use of trademarks. Fourth, unregistered trademark

mainly refers to the fact that the actually used trademark must be legal, that is, it must not violate the prohibition clause stipulated in the trademark law, nor use a trademark similar to a registered trademark, otherwise it will constitute irregular use. I hope my answer is helpful to you. I hope it will be adopted. Thank you.
