Selling other people's products, the defendant's patent infringement

Legal analysis: selling other people's patented products without the permission of the patentee constitutes infringement. However, if the seller doesn't know that he sells the patented infringing products without the permission of the patentee and can prove the legal source of the products, he will not be liable for compensation, but he needs to stop selling the patented infringing products immediately.

Legal basis: After the patent right for inventions and utility models is granted in Article 11 of the Patent Law of People's Republic of China (PRC), except as otherwise provided in this Law, no unit or individual may exploit the patent without the permission of the patentee, that is, they may not manufacture, use, promise to sell, sell or import their patented products for production and business purposes, or use their patented methods and use, promise to sell, sell or import products directly obtained according to the patented methods. After the design patent is granted, no unit or individual may exploit its patent without the permission of the patentee, that is, it may not manufacture, promise to sell, sell or import its patented product for production and business purposes.
