1. No, R is the abbreviation of REGISTER in English, with a circle R, which is the mark of "registered trademark", which means that this trademark has been applied for registration with the National Trademark Office and has been reviewed and approved by the Trademark Office. Become a registered trademark. Getting the acceptance notice does not mean that the registration has been successful. The trademark cannot be used with the R mark until it is successfully registered. This is not protected by the trademark law.

2. Some people say that you can use TM after receiving the acceptance notice. TM only means that the trademark is being registered and is not protected by law. If the trademark you registered is not successfully registered in the end, it will be very difficult. It is possible that using a trademark during this period may infringe upon the trademark rights of others. Even if there is no infringement, if the brand you operate during this period is good and famous, then this trademark may be registered by others, and ultimately your own trademark will not be registered for a long time.
