The Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Laws in the Trial of Trademark Civil Disputes stipulates that the limitation of action for infringement of the exclusive right to use a registered trademark is two years, counting from the date when the trademark registrant or interested party knows or should know about the infringement. If the trademark registrant or interested party files a lawsuit for more than two years, if the infringement continues at the time of filing the lawsuit, the people's court shall order the defendant to stop the infringement within the validity period of the exclusive right to use the registered trademark, and the amount of compensation for infringement damages shall be calculated two years from the date when the obligee files a lawsuit with the people's court.
