the act of using the trademark of the door without the consent of the other party belongs to trademark infringement. The act of infringing the exclusive right to use a registered trademark stipulated in the Trademark Law includes using the trademark without the permission of the registrant at will, and infringing the trademark of the door may bear criminal responsibility. Article 52 of the Trademark Law of the People's Republic of China stipulates five kinds of infringement of the exclusive right to use a registered trademark: 1. Using a trademark identical with or similar to its registered trademark on the same or similar goods without the permission of the trademark registrant. 2. Selling goods that infringe the exclusive right to use a registered trademark; 3. Unauthorized manufacture of another person's registered trademark logo or sale of a registered trademark logo manufactured or manufactured without authorization; 4, with the consent of the trademark registrant, change its registered trademark and put the goods with the changed trademark on the market again. 5, causing other damage to the exclusive right to use a registered trademark of others. Article 1 of the Supreme People's Court's Interpretation on Several Issues Concerning the Application of Laws in the Trial of Trademark Civil Disputes belongs to the acts that cause other damages to others' exclusive right to register a trademark as stipulated in Item (5) of Article 52 of the Trademark Law: (1) The words that are the same as or similar to others' registered trademarks are prominently used on the same or similar goods as the company's font size, which is easy to mislead the relevant public; (2) Copying, imitating or translating a well-known trademark registered by another person or its main part used as a trademark on different or similar goods, misleading the public, and possibly damaging the interests of the registrant of the well-known trademark; (3) Registering words that are the same as or similar to other people's registered trademarks as domain names, and conducting e-commerce of related goods transactions through this domain name, which is likely to mislead the relevant public.
