Trademark registration itself is a voluntary act, and unregistered trademarks can also be used. However, the use process will not infringe the prior rights holder. Therefore, it is recommended that the trademark be registered before use.
Trademarks and domain names are two different concepts. A trademark is a logo used by a product or service to distinguish other products or services in the same industry; a domain name is a link address of a corporate website. If it is not used as a If you use it in the form of a trademark, you should not be held liable for infringement by others.
However, if this registered domain name is also used in a prominent position on the website page as a logo for corporate promotion or product promotion, it may constitute infringement, and there should be no liability for infringement. Refer to the Trademark Law to determine that the person who applied for a registered trademark earlier has the corresponding right to use it.
