Which department should I contact for patent infringement?

[Advanced intellectual property]: Patent rights are infringed by others and are mainly protected by administrative and judicial means.

From the perspective of administrative management, the main administrative departments at present include the Intellectual Property Office, the Science and Technology Bureau, and the administrative department for industry and commerce. You can report to these departments.

From a judicial point of view, it is more troublesome. It is necessary to collect evidence and then entrust a lawyer to file a patent infringement lawsuit with the court.
