Paragraph 1 of Article 61 of the Patent Law stipulates that "if a patent infringement dispute involves an invention patent of a new product manufacturing method, the unit or individual that manufactures the same product shall provide proof that its product manufacturing method is different from the patented method". Therefore, as long as the product obtained by the method patent is a new product and it can be proved that the product produced by the defendant belongs to the same product as the product obtained by the method patent, the defendant shall bear the responsibility of proving that the method used is different from the patented method, otherwise it will bear the adverse consequences of losing the case. This clause seems to relieve the burden of proof for the patent holder of e-commerce, but it is actually beneficial for him to claim the patent right. However, because e-commerce technology has the characteristics of networking and digitalization, there are many legal problems to be solved urgently in the application of inversion of evidence.
