Hello, poster!
R =register, used in trademarks, means "registered trademark".
Trademarks are divided into unregistered trademarks and registered trademarks.
Registered trademarks are protected by national laws and are generally marked with R;
Unregistered trademarks are generally not protected by law and are generally marked with TM.
(Intellectual property rights mainly refer to copyright, trademark rights, patent rights, etc.)
I hope my answer can solve your problem and be helpful to you. I wish you a happy day!
