Even unwittingly selling goods that infringe the exclusive right to use a registered trademark constitutes infringement of the exclusive right to use a registered trademark. At the same time, the law stipulates that if the infringer doesn't know and can prove that the goods were legally obtained by himself and explain the supplier, the administrative department for industry and commerce shall order him to stop selling. Uninformed infringers also need to bear the tort liability of stopping selling the product and providing purchase channels to assist in investigating the source of fake and inferior products. Paragraph 2 of Article 60 of the Trademark Law clearly stipulates that if the sale of a commodity that is unknown to infringe the exclusive right to use a registered trademark can prove that the commodity was legally obtained by itself and explained to the supplier, the administrative department for industry and commerce shall order it to stop selling.
