If someone else misappropriates your company's brand to conduct illegal direct selling training activities, it will infringe on your company's trademark rights. As a rights holder, you can use legal means to remedy your rights. You can file a lawsuit in court to demand that the other party stop the infringement and compensate for losses by calling the police and fixing evidence. If you do not use the above legal methods and use violence to beat the infringer, although the other party infringes your trademark rights first, your beating is definitely illegal and you will need to bear responsibility. If you injure someone else, as long as the injury is minor, it constitutes intentional injury and you need to bear criminal responsibility. If you cause serious injury, you may be sentenced to more than ten years in prison. Even if it does not constitute minor injuries, it may still constitute the crime of picking quarrels and provoking trouble. Even the most minor beatings will be punished by public security management, including fines and administrative detention. At the same time, you need to be responsible for compensation for the injured person's medical expenses, nursing expenses, lost work expenses, disability compensation and other losses. It is really not worth the loss to turn yourself from a reasonable victim to an unreasonable defendant. It is recommended that you resolve it through legal channels and ask the other party to stop the infringement and compensate for the losses.
