Article 64 of the Trademark Law of People's Republic of China (PRC) * * * Where the exclusive right holder of a registered trademark claims compensation, and the accused infringer defends on the grounds that the exclusive right holder of a registered trademark has not used the registered trademark, the people's court may require the exclusive right holder of a registered trademark to provide evidence of the actual use of the registered trademark in the previous three years. If the exclusive right holder of a registered trademark cannot prove that the registered trademark has been actually used in the first three years, nor can he prove that he has suffered other losses due to infringement, the accused infringer shall not be liable for compensation. If you sell a commodity that you don't know is an infringement of the exclusive right to use a registered trademark, and you can prove that the commodity was legally obtained by yourself and explain the supplier, you will not be liable for compensation.
