Hello! R stands for registered trademark, and R is the abbreviation of registered trademark. TM is the English abbreviation of trademark, which is considered by many people in China to be a trademark that is being applied for but has not obtained a registration certificate. A trademark has two signs: R and TM. It is likely that this trademark is a combined trademark, which consists of two or more elements, some of which have successfully applied for registration before, and the other part is being applied for acceptance.
