Similar goods refer to certain similarities in functions, uses, raw materials used, sales channels and consumers. If the same or similar trademarks are used, it is easy for the relevant public to think that they have a specific connection and make consumers mistakenly think that they are goods produced by the same enterprise. Similar service refers to certain similarity in service purpose, content, method and object. If the same or similar trademarks are used, it is easy for the relevant public to think that there is a specific connection and make consumers mistakenly think that they are services provided by the same enterprise. The similar goods and services in the Discrimination Table enable the trademark authorities to sum up many years of practical work experience for the needs of trademark retrieval, examination and management, and solicit opinions from various departments extensively, and combine some goods or services with related characteristics and easy to cause errors for editing. Discrimination tables cannot exhaust all similar goods and services. To determine whether goods or services are similar, we should make a comprehensive judgment based on the general understanding of goods or services by the relevant public. The discrimination table can be used as a reference for trademark examiners, trademark agents and trademark registration applicants to judge similar goods or services, and also as a reference for administrative organs and judicial organs to judge similar goods or services when handling trademark cases.
