In terms of legislation, infringement of intellectual property rights can be divided into direct infringement and indirect infringement. The law stipulates different fault conditions and penalty standards. The so-called indirect infringement has two meanings: First, it refers to the act itself does not constitute infringement, but its behavior helps and leads to the occurrence of direct infringement, thus causing damage to the right holder, also known as "secondary infringement" . For example, in the field of copyright, the act of intentionally selling, leasing, and importing infringing goods; in the field of patent rights, the act of intentionally manufacturing and selling key components that can only be used for patented products; in the field of trademark rights, intentionally infringing upon the rights of others. Trademark rights activities provide convenient conditions for warehousing, transportation, mailing, concealment, etc. The second means that the "actor" has not engaged in any infringement, but due to the existence of specific social relationships, he must bear certain liability for the infringement of others according to law. For example, the tortious acts committed by the legal agent against the incapacitated person, the tortious acts committed by the employer against the employee for completing the job, the tortious acts committed by the principal against the trustee for the performance of the entrustment contract, etc. are all indirect tortfeasors. The above-mentioned indirect infringements and direct infringements shall bear the same infringement liability.
