A trademark is a sign used to distinguish goods or services. It is used on identical or similar goods or services and can only be used on specific goods or services. As stipulated in my country's Trademark Law, the exclusive right to register a trademark is limited to the approved registered trademark and the approved goods for use. Domain name is a method used to solve the problem of IP address correspondence. It was created to facilitate people to use the Internet. It is not directly related to goods or services, and cannot exist independently from the Internet. The mutual distinction and exclusivity of trademarks are based on the identity or similarity of goods or services. Different goods or services usually do not generate such requirements (except for well-known trademarks); therefore, different legal entities in the same country or different countries will not have such requirements. It is a common phenomenon that the same trademark enjoys independent rights. Domain names are absolutely unique on a global scale and do not differ based on legal entities, types of goods or services, countries or regions. This uniqueness is the basis of its absolute exclusivity and is determined by the technical characteristics of the Internet domain name system.
