1. You can sue. This behavior of the embezzler is an infringement of the company's name right. 3. If you want to sue, you need to prepare the following evidence: There are two main ways to infringe others' names: (1) register others' names as your own. For unauthorized use of another person's font size as the font size of the same area, you can request the revocation of its font size through judicial channels and demand compensation for losses. However, if someone else's name is not registered as the name of his own enterprise in the same administrative region, it cannot be protected by the Regulations on the Administration of Enterprise Name Registration. Because our country's enterprise name (trade name) adopts the regional registration system. That is, the administrative departments for industry and commerce in each administrative region are the registration authorities, which are responsible for the registration of industrial and commercial enterprises in their respective regions, while the state administrative departments for industry and commerce are only in charge of and responsible for the registration of companies and enterprises nationwide. Enjoy the exclusive right to use the enterprise name and trade name only in the registered area. In this case, only the anti-unfair competition law can be used to protect it. (two) the name of another person is registered as a trademark. According to Article 4 of the Opinions on Solving Several Problems in Trademarks and Enterprise Names issued by the State Administration for Industry and Commerce 1999 (Industrial and Commercial Enterprise Word [1999] No.81) on April 5, the words in the trademarks are the same as or similar to the font size in the enterprise name, which confuses others about the market subject and the source of its goods or services (. According to the Opinions on Solving Several Problems of Trademarks and Enterprise Names, the obligee must lodge a complaint with the State Administration for Industry and Commerce or the provincial administration for industry and commerce in written form within five years from the date of trademark registration or enterprise name registration, and attach relevant evidence materials that his rights and interests have been damaged. The administrative department for industry and commerce shall be responsible for investigating and revoking the name of the enterprise with the owner's name used by it without authorization. This kind of behavior infringes on the exclusive right of others' enterprise names. Article 27 of the Regulations on the Administration of Enterprise Name Registration stipulates that anyone who uses an enterprise name registered by another person without authorization or commits other acts that infringe on the exclusive right of another person's enterprise name may request the registration authority where the infringer is located to handle it. The registration authority has the right to order the infringer to stop the infringement, compensate the infringed for the losses caused by the infringement, confiscate the illegal income and impose a fine of not less than 5,000 yuan but not more than 50,000 yuan. Anyone who infringes upon the exclusive right to use another person's enterprise name may also directly bring a suit in a people's court.
