Trademark is a special legal term. A brand or a part of a brand is called a "trademark" after it is registered by the relevant government departments according to law. Trademarks are protected by law, and registrants have exclusive rights. Famous trademarks in the international market are often registered in many countries. There is a difference between "registered trademark" and "unregistered trademark" in China. A registered trademark is a trademark protected by law after being registered by the relevant government departments, while an unregistered trademark is not protected by trademark law.
