What does it mean that the applicant or patentee entrusts a patent agency to handle the fee reduction procedures?

To apply for a patent, you need to pay the corresponding fees to the state, including the application fee, the actual examination fee for the invention patent, the registration fee at the time of authorization, and the maintenance fee after authorization. In order to encourage patent application and implement the subsidy policy for enterprises or individuals, the state stipulates that enterprises or individuals can reduce or exempt the relevant expenses for patent application when funds are tight. Intuitively speaking, enterprises can reduce or exempt 70% and individuals can reduce or exempt 85%. These expenses include the application fee, the actual examination fee for the invention patent and the maintenance fee for the first three years.
