There are many classifications of trademarks. According to different angles and standards, trademarks can be divided into different categories. (1) According to the composition of the trademark, it is 1 and word mark: it is composed of relatively standardized numbers, letters and characters, and has remarkable characteristics. Such as "96446" composed of simple numbers, "Dell" composed of simple letters and "Sohu" composed of simple words. 2. Graphic trademark: a trademark composed of plane or three-dimensional graphics. For example, the Y graphic logo of the outer ring of Mercedes-Benz in Germany, the shell graphic trademark of Shell International Petroleum Co., Ltd. and so on. 3. Combination trademark: it is composed of numbers, letters, characters, graphics and colors. For example, the circular power grid icon of State Grid Corporation and the trademark Windows98 composed of Chinese and English. (2) Classification by trademark use 1. Trade mark: a mark used on a specific commodity to indicate the source of the commodity. Such as "Youngor" (suit), Adidas (football) and Qingdao brand (beer). 2. Service trademark: a symbol used to distinguish the services provided by service providers in the service items provided to the society. Such as China Petrochemical logo, Global logo, and Boiling Fish Restaurant Logo. 3. Commercial trademarks: logos affixed to commodities sold by commercial enterprises selling commodities, such as those affixed to some commodities such as Carrefour and Meilianmei Supermarket. 4. Certification trademark: a mark controlled by an organization with the ability to supervise goods or services and used by units or individuals outside the organization to prove the origin, raw materials, manufacturing methods, quality or other specific qualities of the goods or services. Such as Great Wall electrician certification mark, wool mark, etc. (3) Classification by trademark particularity 1. Well-known trademark: a trademark that is widely known to the relevant public and enjoys a high reputation in China. Such as Lenovo and Tong Ren Tang. 2. Common trademark: the owner of the same trademark registers two or more similar trademarks on the same or similar goods and services. For example, Quanjude Food Group also registered Quanjude, Quanjude, Junjude, Junjude, Junjude, Dejude and other trademarks, which constituted a joint trademark. If Beijing Electric Power Company wants to register the trademarks of Nortel, Jingdian, Gong Bei and Gong Jing, it is a joint trademark. 3. Defensive trademark: The trademark owner will register the same trademark in a category other than the goods and services approved for use of the trademark, so as to prevent other operators from maliciously registering and using it. For example, Haier Group has registered the "Haier" trademark in all commodity categories. China State Grid Corporation has registered in all categories and is not prepared to use them all, so the Globe trademark is also a defensive trademark. 4. Geographical indications: A commodity will have specific quality, reputation or other characteristics due to the influence of natural factors or human factors unique to a certain area. The specific symbol used to show that a commodity comes from this area is a geographical indication. Such as "Lanzhou Lily", "Korla Fragrant Pear" and "Xinyang Maojian Tea". 5. A collective trademark refers to a sign registered in the name of a group, association or other organization, which is used by members of the organization in business activities to show the membership of users in the organization. The Trademark Law and the Regulations on the Implementation of Trademarks stipulate that the main body of the applicant for collective trademark registration should be an organization, which can be an industrial and commercial group, association, guild or other organization, but it cannot be a single enterprise legal person or natural person. Judging from this regulation, the ball logo of State Grid Corporation of China has been authorized to be used by all its subsidiaries, but it is not a collective trademark. (4) Classification according to whether the trademark is registered 1. Registered trademark: a trademark that has applied to the State Trademark Office for registration and has been approved for use. 2. Unregistered trademarks: trademarks of commodities used by users without applying for registration with the State Trademark Office. According to China's Trademark Law and other industrial and commercial management regulations, only registered trademarks are protected by law. The use of trademarks by unregistered trademark users does not violate the provisions of China's trademark laws and regulations, and may not infringe upon the legitimate rights and interests of registered trademark owners.
