1. If it is really difficult to apply for paying the patent fee, you can request the Patent Office to postpone the filing fee, examination fee, maintenance fee, reexamination fee and annual fee of the application for a patent for invention within three years after the patent is approved. All other patent fees shall be paid as required.
Two, the proportion of individuals required to slow down is not more than 75%, and the proportion of units required 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.
