Personally, I think well-known trademarks have high gold content. Well-known trademarks exist objectively. Believe it or not, their popularity and reputation in the hearts of relevant consumers are very high. Both the Paris Convention and the Trademark Law of People's Republic of China (PRC) give affirmation and special protection to well-known trademarks. Well-known trademarks in China have been recognized before, but the application materials need a trademark registration certificate. Famous brand is consumers' overall cognitive impression of a trademark. So far, there is no legal recognition. Previously, only departmental regulations had corresponding recognition provisions.
