If trademark infringement is sued, you should actively respond. The plaintiff in a trademark infringement lawsuit shall be the owner or interested party of a registered trademark. If the plaintiff is not the owner or interested party of the registered trademark, the defendant may make an unconditional defense against the plaintiff. 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 becomes aware of the infringement. If the trademark registrant or interested party files a lawsuit for more than two years and the infringement continues during the lawsuit, the people's court shall order the defendant to stop the infringement within the validity period of the exclusive right to use a registered trademark.
