Using other people’s patents without permission will result in fines or even prison sentences.
The crime of patent counterfeiting stipulated in my country's criminal law refers to serious acts of violating national patent regulations and counterfeiting other people's patents. The specific forms of counterfeiting patents include: registering patents by deceptive means and impersonating other people's patents; marking other people's patent marks or patent numbers on non-patented products or patents; counterfeiting other people's patents, misappropriating other people's patents, practicing other people's patents without authorization, and deliberately trafficking Counterfeiting or altering products patented by others, counterfeiting or manufacturing others' patented marks without authorization, intentionally selling forged or unauthorizedly manufactured patented marks by others, importing products counterfeiting others' patents, passing off patents, etc. Article 216 of my country's Criminal Law stipulates that anyone who counterfeits 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 solely be fined. Therefore, the unauthorized use of someone else’s patent on a product, if the circumstances are serious, constitutes the crime of patent counterfeiting.
