Legal basis: Article 47 of the Trademark Law of People's Republic of China (PRC) A registered trademark that has been declared invalid according to the provisions of Articles 44 and 45 of this Law shall be announced by the Trademark Office, and the exclusive right to use the registered trademark shall be deemed as nonexistent from the beginning. The decision or ruling declaring a registered trademark invalid has no retrospective effect on the judgment or ruling of trademark infringement cases made and executed by the people's court before the invalidation, the conciliation statement, the decision on handling trademark infringement cases made and executed by the administrative department for industry and commerce, and the trademark transfer or use license contract that has been performed. However, if losses are caused to others due to the malice of the trademark registrant, compensation shall be made. If the trademark infringement compensation, trademark transfer fee and trademark use fee are not returned in accordance with the provisions of the preceding paragraph, which obviously violates the principle of fairness, they shall be returned in whole or in part.
