What about the proof of patent fee slowdown?

(1) individual: truthfully fill in my income in the last year in the fee waiver request, and submit the annual income certificate issued by my unit. If I have no fixed job, submit the certificate issued by the county-level civil affairs department or the township people's government (street office) of my domicile or habitual residence.

(2) Enterprises: If they are in financial difficulties, they should truthfully fill in the application for fee reduction and submit a copy of the annual enterprise income tax return for the previous year. During the settlement period, the enterprise shall submit a copy of the annual enterprise income tax return for the previous year.

(3) Institutions, social organizations and non-profit scientific research institutions: submit copies of legal person certification materials.

If a patent applicant or patentee submits a patent fee waiver request through the patent affairs service system and it is approved for filing after examination, it only needs to submit the fee waiver request again within a natural year without submitting relevant certification materials. Bajie Intellectual Property can assist the applicant to handle specific matters.
