Patent holders can use the patent law to protect their legitimate rights and interests. Specifically, the first step is to collect evidence to prove that "imitation" is an infringement, and the second step is to negotiate with the infringer after obtaining evidence and ask him to stop the infringement and compensate for the losses. If the two parties fail to negotiate, the patentee shall bring a lawsuit to the people's court with jurisdiction and demand to safeguard the legitimate rights and interests according to law.
