How to submit the annual patent fee reduction request?

We introduced a number of patents first, and then deferred the patent fees for filing. These patents are applied in paper and electronic form. Now it seems that the CPC client can't submit the fee reduction request separately, right? Measures to slow down the patent application fee: 1. If it is really difficult to apply for patent payment, you may request the Patent Office to postpone the payment of the application fee, the examination fee and maintenance fee of the application for a patent for invention, the reexamination fee and the annual fee within three years after the patent is approved. Other patent fees shall be paid in accordance with the provisions; Two, the proportion of individuals to slow down is not more than 75%, and the proportion of units to slow down is not more than 50%; Three, the request to slow down the patent fee shall submit a request for fee reduction, the individual shall pay 25% of the prescribed fee at the same time, and the unit shall pay 50% of the prescribed fee at the same time; Four, at the same time of filing a patent application, you can request to postpone the payment of the above five fees. After filing a patent application, only the unexpired fees other than the application fee may request an extension, but the request shall be filed at least two months before the expiration of the relevant fee period; 5. If an individual requests to slow down, his annual income shall be stated in the fee for requesting to slow down. Two or more patent applicants shall fill in the annual income of each person. When necessary, the Patent Office may request an annual income certificate. If the unit requests to postpone the delivery, it shall not only explain the reasons for the delay, but also attach the certificate from the superior competent department. If it does not meet the requirements or fails to provide relevant certificates, it shall be deemed that no request has been made; 6. The request for fee reduction shall be examined and approved by the Patent Office. If it is not approved, it shall, after receiving the notice from the Patent Office, pay the fee according to the specified amount within the time limit stipulated in the Patent Law and its detailed rules for implementation; Seven, the applicant or the patentee shall pay the extension fee after the invention has obtained economic benefits or other economic income. How is the annual patent fee reduced? The patent applicant or patentee may request the reduction or exemption of the following patent fees: 1, application fee (excluding publication and printing fee and application surcharge); 2. Substantive examination fee for an application for a patent for invention; 3. Annual fee (annual fee within six years from the year when the patent right is granted); 4. Review fee. If the patent applicant or patentee meets one of the following conditions, he may request China National Intellectual Property Administration to reduce part of the patent fee: 1, an individual with an average monthly income of less than 3,500 yuan (42,000 yuan a year); 2. Enterprises with taxable income of less than 300,000 yuan in the previous year; 3, institutions, social organizations, non-profit scientific research institutions. Where two or more individuals or units are the same patent applicant or patentee, they shall abide by the provisions of the preceding paragraph respectively.
