The main reason is to protect the rights and interests of registered trademarks. When the exclusive right to use a trademark is infringed, the court will determine whether the trademark is a registered trademark based on whether there is an r mark on the trademark. If you forget to add the R logo, the trademark has been infringed and the court will still treat it lightly.

Moreover, if your registered trademark is used without the R mark, even if your exclusive rights are infringed by others, when you claim compensation from the infringer, the infringer may say that you did not know your trademark at all. The trademark is not a registered trademark and the grounds for resisting compensation for economic losses are raised.

Therefore, trademark registration applicants must not only apply for a trademark in accordance with the trademark registration procedures, but also use the trademark correctly after successful trademark registration to better protect trademark rights.
