A trademark refers to a trademark being registered. The Trademark Law does not stipulate trademarks marked with TM, and trademarks that have not been approved for registration can use TM, but they are not protected by law.

R trademark refers to a trademark that has been approved and registered by the Trademark Office. It can be marked as a "registered trademark" on commodities, packages or other accessories, and can be marked in the upper right corner or the lower right corner of the trademark. As long as the trademark is marked with R, it means that the trademark has the exclusive right and is protected by law.
