TM is the abbreviation of English "Trademark". TM is generally used in China for trademarks that have been accepted by the Trademark Office (receiving the acceptance notice) but have not been formally registered successfully. When using the brand, adding TM will help to be used as evidence in future trademark disputes to prove that this word or logo has been consciously used as a trademark. R is the abbreviation of "Register" and the mark of "registered trademark", which means that the trademark has applied for registration in the State Trademark Office, and has been approved by the Trademark Office to become a registered trademark.
Article 63 of the Regulations for the Implementation of the Trademark Law stipulates: "Where a registered trademark is used, a' registered trademark' or a registration mark may be marked on the commodity and its packaging, instructions or other accessories. Registration marks include comments and R, and the use of registration marks should be marked in the upper right corner or the lower right corner of the trademark. "
