Dabai should be a common trademark, but its influence goes beyond the types of well-known trademarks. On the morning of April, 2065438+2005 1, Dazan published a piece of good news in the official Weibo. It is reported that Walter Disney Animation Company may grant Great God Network Technology (Shenzhen) Co., Ltd. the right to use the animated image of Big Hero 6 inflatable robot Dabai. At that time, no enterprise or individual may use the image of Dabai for any commercial purpose without the permission of the above two companies. 1. How long is the protection period of well-known trademarks? Well-known trademarks do not have the problem of the length of validity, and they can also be said to be permanent. There is no accurate concept of the term of protection of well-known trademarks, because the validity period of registered trademarks is 10 years, even if 10 years expires, it needs to be renewed. If it has not expired, the well-known trademark will also be cancelled. Others can also apply for this trademark again. 2. What are the protections for well-known trademarks in China? The legislation on the protection of well-known trademarks in China is relatively late. The extended protection of well-known trademarks in the Interim Provisions on the Recognition and Administration of Well-known Trademarks is mainly embodied in three aspects: 1, and the prohibition of improper registration. Where an application for registration of a trademark identical with or similar to another person's well-known trademark on a non-similar commodity may harm the rights and interests of the registrant of a well-known trademark, the Trademark Office may reject its application for registration. A registered well-known trademark may be revoked by the Trademark Review and Adjudication Board. 2. Improper use is prohibited. Where a trademark identical with or similar to another person's well-known trademark is used on non-similar goods, and it is implied that the goods have some connection with the well-known trademark registrant, which may damage the rights and interests of the well-known trademark registrant, the well-known trademark registrant may request the administrative department for industry and commerce to stop it. 3. It is forbidden to use it as a trade name. Since the date when a well-known trademark is recognized, the administrative department for industry and commerce shall not register it if others regard the same or similar words as part of the enterprise name, which may cause public misunderstanding; Where it has been registered, the registrant of a well-known trademark may request cancellation. Article 13 of China's revised Trademark Law extends the protection scope of well-known trademarks to non-similar goods or services, and formally establishes the extended protection of well-known trademarks in the form of legislation.
