Legal basis: Paragraph 2 of Article 64 of the Trademark Law: "If you sell a commodity that you don't know is an infringement of the exclusive right to use a registered trademark, you can prove that the commodity was legally obtained by yourself and explain it to the supplier, and you will not be liable for compensation."
Generally, there are calculation methods for the compensation amount of the infringer, such as actual loss, infringer's income and reasonable multiple commission, which should be determined according to the specific situation.
Legal basis: the amount of compensation for infringement of the exclusive right to use a trademark in Article 63 of the Trademark Law shall be determined according to the actual losses suffered by the obligee due to infringement; If the actual loss is difficult to determine, it can be determined according to the interests obtained by the infringer due to infringement; If it is difficult to determine the loss of the obligee or the interests of the infringer, it shall be reasonably determined by referring to the multiple of the trademark license fee.
