Before the law enforcement agency discovers the crime of infringing the exclusive right to use a registered trademark, it reports the clues of the crime of infringing the exclusive right to use a registered trademark, such as counterfeiting a registered trademark, to the public security organ in the form of written materials, telephone calls or the Internet, which are verified by the public security organ. Informants include natural persons, legal persons and organizations. "Those who report to the police, report or accuse the counterfeited party and their families or agents are not included." The scope of clues includes: criminal clues of counterfeiting registered trademarks, criminal clues of selling counterfeit registered trademarks and criminal clues of illegally manufacturing and selling illegally manufactured registered trademarks. The accuracy of reporting facts and the cooperation degree of informants will be divided into four grades, and the actual reward amount of informants is "basic reward amount" × "reporting grade weight". Among them, the first-level report weight 100%, the second-level report weight 80%, the third-level report weight 60%, and the fourth-level report weight 40%.
