the difference is that TM is a registered trademark and is not protected by law. R trademark has been successfully registered and has a trademark certificate, which is protected by law.

trademark registration takes about one year and 12 months. After three months of formal examination after submitting the materials for trademark application, the Trademark Office will issue a notice of acceptance of the trademark. At this time, the trademark applicant can use TM mark on the product, but at this time, the trademark brand is not protected by law. After the trademark has completely passed the six-month substantive examination and the three-month announcement period, the trademark certificate can be used with the R mark when it is officially issued, which is protected by law.

so I hope that parents who are using and registering trademarks will pay attention to this point. This is a distinction.
