Trademark infringement refers to: the actor uses the same or similar trademark on the same or similar goods without the permission of the trademark owner, or other acts that interfere with or hinder the trademark owner from using its registered trademark and damage the legitimate rights and interests of the trademark owner. The natural person or legal person whose trademark exclusive right is infringed upon when the actor sells goods that he knows or should know are counterfeit registered trademarks has the civil right to demand the infringer to stop the infringement, eliminate the influence and compensate for the losses.

Article 52 of the Trademark Law stipulates that one of the following acts is committed; Violations of the exclusive right to use a registered trademark include:

1. Use a trademark that is the same as or similar to its registered trademark on the same or similar goods without the permission of the trademark registrant.

2. Selling goods that infringe the exclusive right to use a registered trademark;

3. Forging or manufacturing others' registered trademarks without authorization or selling forged or manufactured registered trademarks without authorization;

4. Without the consent of the trademark registrant. Changing the registered trademark and putting the goods with the changed trademark on the market again. But in fact, the exclusive right to use a trademark protected by the Trademark Law is exercised by the subject; Exercising different rights forms different subjects of rights; The stipulated torts are all carried out by the subject, and the subjects who carry out different acts form different torts. Therefore; Grasping trademark infringement from the perspective of subject seems to be more conducive to understanding the relationship between subject, litigation rights and responsibilities.
