For example, for an application for a patent for invention, the application fee and printing fee have been paid before, and other fees have not been paid, and then the application is postponed. If the fee reduction is approved, the subsequent actual examination fee and annual fee for three years after authorization can be reduced, and the application fee already paid will not be refunded.
To handle the fee reduction procedures, you need to fill in 1 fee reduction request and 1 fee reduction certificate, and then submit them to the acceptance office of the State Information Bureau (you can register and mail them).
The Request for Fee Reduction Form was downloaded from official website, State Information Bureau; Please go to the local intellectual property office to apply for the fee waiver certificate (the fee waiver certificate is handled differently in different places, please consult the local intellectual property office for details).
