Hello dear, I am very happy to answer your question. TM is the abbreviation of "TradeMark" in English, which means the trademark symbol. That is, the words, graphics or symbols marked with tm are trademarks and have been submitted to the Trademark Office for review, but they may not have been successfully registered. If the trademark is marked with "R", R is the abbreviation of rsgister, which means registered trademark in the trademark. R stands for "registered trademark", which means that the trademark has been applied for registration with the National Trademark Office and has been reviewed by the Trademark Office. If you have any other questions, please click on my avatar to communicate with me.

Passed the review and became a registered trademark.
