1. First of all, sellers should check whether their products are infringing. If there is infringement, they can only apologize to the seller who complained about your infringement and remove your infringing listing. If there is no infringement or authorization, the seller can open a case to contact Amazon official and provide relevant certification materials such as product authorization to prove that they are not infringing. 2. Secondly, the seller should find out the application of trademark patent, invention patent, design patent or copyright of the complaining party. If the other party provides patent details and confirms the product infringement, the seller will directly remove the listing. If the complaining party insists on demanding compensation, the seller should actively communicate with the complaining party. Generally speaking, it can withdraw the complaint by signing a letter of guarantee or giving some compensation. If the other party asks for more compensation, it is estimated that the account will be abolished, and the seller should consider whether his account has the significance of saving, or the seller who has the conditions can also ask an intellectual property lawyer to communicate on his behalf. 3. Finally, if Amazon directly removed your listing, you should contact the complainant to provide proof of infringement. If the other party refuses to provide it, the seller can contact Amazon to complain that the other party refuses to provide any proof of infringement, and there is a malicious complaint. Let Amazon restore your listing.
