Infringement of the exclusive right to use a registered trademark, punishable by a fine of less than 3 times the amount of illegal business; If the illegal business amount cannot be calculated, the fine amount shall be less than 654.38+10,000 yuan. In addition, the key to the transfer of trademark infringement cases suspected of constituting a crime to judicial organs is also the calculation of illegal business amount. The value of the infringing products that have been sold shall be calculated according to the actual selling price. The value of infringing products manufactured, stored, transported and unsold shall be calculated according to the marked price or actual average selling price of the infringing products that have been identified. If the infringing product is not marked or its actual sales price cannot be determined, it shall be calculated according to the intermediate market price of the infringed product. In some trademark infringement cases, some infringers usually take measures such as not issuing purchase and sale documents, leaving no purchase and sale records, isolating warehouse inventory from the sales site, and placing only a small number of infringing goods samples at the sales site to conceal the real situation of infringement, set obstacles for administrative law enforcement, and try to escape the law and escape the blow. Therefore, to put it simply, "the illegal business amount cannot be calculated" applies to the case that the infringer fails to provide or truthfully and effectively provide information that can be used to verify his illegal business amount, including documents, records, suppliers, etc. And the trademark administrative law enforcement agencies can't find out his illegal business.
