What responsibility should the patent agency bear for reminding the annual fee that the patent is invalid?

Bear civil liability for compensation for economic losses. The patent law implements the statutory principle of patent infringement, except that the law clearly stipulates that it is an act of patent infringement, even if other acts are related to patent rights, they are not patent infringement. If the applicant or the registered patentee fails to perform the obligation of good management without justifiable reasons, resulting in the termination or loss of rights and damaging the legitimate rights and interests of the real obligee, it constitutes an infringement of the property rights of others and shall bear civil liability for compensation for economic losses.
