If a trademark holder requests the protection of a well-known trademark in accordance with Article 13 of the Trademark Law, he shall submit evidence that his trademark constitutes a well-known trademark. The Trademark Office and the Trademark Review and Adjudication Board shall, according to the needs of examining and handling cases and the evidence materials submitted by the parties, identify well-known trademarks in accordance with the provisions of Article 14 of the Trademark Law.
Article 13 of the Trademark Law of People's Republic of China (PRC) applies for registration of identical or similar goods. A trademark is a well-known trademark that has been copied, imitated or translated by others and is unregistered in China. If it is easy to cause confusion, it will not be registered and it is prohibited to use it. Where a trademark applied for registration on different or dissimilar goods is a well-known trademark registered by others in China, misleading the public and possibly harming the interests of the registrant of the well-known trademark, it shall not be registered and its use shall be prohibited.
