first of all, it is necessary to determine whether it meets the conditions of fee reduction. If the patent applicant is an enterprise, the requirement is that the taxable income of the enterprise in the previous year is less than 3, yuan, and the proof materials are the annual tax return of the enterprise in the previous year (stamped with the tax stamp and the official seal of the enterprise) and a copy of the business license (stamped with the official seal of the enterprise). For an individual, the average monthly income in the previous year should be less than 3,5 yuan (42, yuan per year), and the proof materials are the income certificate (stamped with the company seal) and the copy of the ID card (signature) of the individual with an annual income of less than 42, yuan.
then, log in to the patent affairs service system, make online filing, and mail the certification materials to the patent agency in the province where you are located (contact information will be provided in the system). You can log in to the patent affairs service system at any time to check the filing progress. If the information is complete, you can usually find the results the next day.
