What are the consequences of unauthorized use of other people's patents?

The crime of counterfeiting patent stipulated in China's criminal law refers to the act of counterfeiting another person's patent in violation of national patent laws and regulations, and the circumstances are serious. The specific manifestations of counterfeit patents are: registering patents by deception and using others' patents fraudulently; Marking other people's patent marks or patent numbers on non-patented products or patents; Counterfeiting other people's patents, stealing other people's patents, carrying out other people's patents without authorization, deliberately trafficking in products with counterfeit or altered patents, forging and making other people's patent marks without authorization, deliberately selling forged or unauthorized patent marks, importing products with counterfeit patents, and passing off patents. Article 2 16 of China's criminal law stipulates that whoever imitates another person's patent, if the circumstances are serious, shall be sentenced to fixed-term imprisonment of not more than three years or criminal detention, and shall also or only be fined. Therefore, unauthorized use of other people's patents on products, if the circumstances are serious, constitutes a crime of counterfeiting patents.
