R: registered trademark logo. To put it simply: R is a registered trademark and cannot be used fraudulently.

The Implementation Regulations of China's Trademark Law stipulate that when using a registered trademark, a "registered trademark" or registered mark may be indicated on goods, product packaging, instructions or other attachments.

Registration marks include (note plus ○) and (?). The registration mark should be marked on the upper right corner or lower right corner of the trademark (where R is the abbreviation of REGISTER).

Extended information:

Some trademarks are marked with TM in the upper right corner. TM is the abbreviation of TRADEMARK. American trademarks are usually marked with TM, which does not necessarily refer to a registered trademark.

"TM" does not have clear legal provisions in our country. Generally, it is customary in the industry to refer to a trademark that has been accepted by the Trademark Office (obtained an acceptance notice) but has not yet been officially registered. When using a brand, adding TM can be used as evidence to prove that we are consciously using this word or logo as a trademark in the event of a trademark dispute.
