Can I reduce the fee after applying for a patent?

You can apply for exemption, but the expenses you have incurred are not entitled to exemption. When your application for exemption is approved, the expenses incurred in the subsequent procedures will be entitled to exemption. For example, if you apply for a patent for utility model without applying for exemption, the application fee will be 500 yuan. After paying the application fee, the fee reduction request is processed and approved. In the subsequent authorization stage, the registration fee and the annual fee of the current year are calculated according to the reduced amount.
