Patent administrative adjudication refers to the act that the relevant administrative organs arbitrate patent disputes closely related to administrative activities according to the application of the parties and the authorization of laws and regulations. The department in charge of patent work carries out patent administrative law enforcement, that is, dealing with patent infringement disputes, mediating patent disputes and investigating and dealing with patent counterfeiting. In the starting process, the administrative ruling can only be filed according to the application, and the administrative law enforcement can be filed according to the application or ex officio. In the scope of accepting cases, because administrative law enforcement can deal with counterfeit patents ex officio, its scope of accepting cases is wider. Whether it is administrative law enforcement or administrative ruling, mediation can be carried out in the process of handling disputes. If you are not satisfied with the result, you can bring an administrative or civil lawsuit according to different specific reasons. The administrative organ is always in the middle position in the process of administrative adjudication, but it may be the subject of law enforcement in the process of administrative law enforcement.
