Limitation of action refers to the system that the obligee whose civil rights have been infringed fails to exercise his rights within the statutory limitation period, and loses the right to request the people's court to compel the obligor to perform his obligations according to the litigation procedure when the limitation period expires. Generally speaking, the limitation of action means that the obligee should request the people's court to protect his legitimate rights and interests within the effective period stipulated by law after his rights are infringed; A lawsuit brought to a people's court beyond the validity period prescribed by law shall not be protected by law.

Second, the law stipulates that

China's Trademark Law and its implementing regulations do not clearly stipulate the limitation of action for infringement of trademark rights. According to the Interpretation of the Supreme People's Court on Several Issues Concerning the Application of Laws in the Trial of Trademark Civil Disputes, 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. Where a trademark registrant or interested party files a lawsuit for more than two years, and the infringement continues when the lawsuit is filed, 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, and the amount of compensation for infringement damages shall be calculated forward for two years from the date when the obligee files a lawsuit with the people's court.

In addition, according to the provisions of the General Principles of the Civil Law on the limitation of action, the limitation of action is calculated from the time when you know or should know that your rights have been violated. However, if more than 20 years have passed since the right was infringed, the people's court will not protect it. Under special circumstances, the people's court may extend the limitation of action.

Third, what should I do if the trademark is infringed?

There are several ways to solve infringement disputes. If the trademark is infringed, it can be solved through the following ways:

1. The advantage of negotiation is that it avoids litigation, does not harm harmony, and can change from a competitor to a partner.

2. The advantage of requesting the administrative organ to handle it is that the procedure is simple and fast, and the infringement can be stopped in time.

3. Prosecuting in the people's court has the advantages of many means and strong effectiveness, but the procedure is complicated.
