If your name is not registered, continue to use it. There are no problems and no consequences. Of course, any trademark will not be resisted when you bid, join or enter the store. Moreover, enterprises do not register trademarks, so there are many hidden dangers and risks. Only registered trademarks can enjoy the exclusive right to use trademarks. Enterprises without registered trademarks are always in a state of insecure rights.
If you are a product without a trademark, it is easy to be imitated by others, and your own rights cannot be guaranteed.
