Trademarks are divided into trademarks and registered trademarks;

A registered trademark is called a registered trademark. Except for some special industries such as tobacco, alcohol and medicine, which require compulsory trademark registration, other general industries do not need to register trademarks. Registration, so as long as you are not in an industry that requires compulsory registration, it is not illegal. However, unregistered trademarks may potentially have other risks, that is, they may have been registered by others, and in this case you will infringe.

In addition, unregistered trademarks, of course, cannot be protected by law and do not have the exclusive right to use them exclusively.
