What certification materials are needed to apply for patent relief?

Where a patent applicant or patentee requests fee reduction, it shall provide the following certification materials according to the type of patent applicant or patentee: 1. If an individual requests fee reduction, he shall truthfully fill in the income of the previous year in the fee reduction request and submit the annual income certificate issued by his unit; If there is no fixed job, submit the certificate issued by the civil affairs department at the county level or the township people's government (street office) where the household registration is located. 2. Where an enterprise requests to reduce or exempt patent fees, it shall truthfully fill in the financial difficulties in the request for fee reduction and exemption, and submit a copy of the enterprise income tax return for the previous year. During the period of final settlement, the enterprise shall submit a copy of the annual enterprise income tax return for the previous year. 3, institutions, social organizations, non-profit scientific research institutions to reduce patent fees, should submit a copy of the legal person certification materials. 4. The certificate issued by the administrative department for patent affairs of the people's government at or above the municipal level shall indicate whether the unit requesting patent fee reduction or exemption is an enterprise, institution or organization, and explain its economic difficulties. Applying for trademark rights requires paying corresponding trademark maintenance fees every year, and applying for patent rights also requires paying corresponding fees, which is the obligation that the patentee should bear in order to maintain patent rights. However, for individuals or units with real economic difficulties, as long as they meet the conditions for fee reduction and can provide true proof materials, they can appropriately reduce their fees.
