Amazon's complaint process for patent infringement requires the complainant to provide clear and effective reasons for prosecution, the plaintiff and the defendant, and the time and place of actual infringement. The complainant must also provide effective evidence to prove that its patent rights have been infringed by other companies, including: relevant intellectual property registrations, site maps, and valid certificates for the legal acquisition of infringing objects. If the patent holder files a complaint, Amazon will collect all relevant information, conduct a serious investigation into the patent infringement, and attach great importance to this incident. If the infringement is confirmed, Amazon will take necessary measures against the infringing products, including immediately removing the products from the Amazon website.
