Legal analysis: First of all, if a lawsuit arises, you will not know about the manufacturer's trademark infringement. You will also provide formal supply certificates and bank payment certificates, indicating that you purchased goods through normal channels and at normal prices. Secondly, if the victim demands compensation and says that he has no money as a dealer, then the manufacturer will bear joint and several liability, and the final court ruling will result in limited enforcement of the manufacturer's property.

Legal basis: "Trademark Law of the People's Republic of China" Article 47 A registered trademark declared invalid in accordance with the provisions of Articles 44 and 45 of this Law shall be registered by the Trademark Law The Bureau shall announce that the exclusive right to use the registered trademark shall be deemed to have ceased to exist from the beginning. Decisions or rulings declaring the registered trademark invalid, judgments, rulings, and mediation documents on trademark infringement cases made and executed by the People's Court before the invalidation, and decisions on handling trademark infringement cases made and executed by the industrial and commercial administration departments, as well as The executed trademark transfer or licensing contract does not have retroactive effect. However, compensation shall be provided for losses caused to others due to the bad faith of the trademark registrant. If the trademark infringement compensation, trademark transfer fees, and trademark usage fees are not returned in accordance with the provisions of the preceding paragraph, which obviously violates the principle of fairness, all or part of the compensation shall be returned.
