On patent issues

First of all, if you can't write the patent application documents yourself, you can find an agent, and then please check the local legal patent agency on China National Intellectual Property Administration. Otherwise, it will be very troublesome to meet a black agent. There are three kinds of patents, the invention patent agency in Jilin Province is about 3500, and the utility model patent agency fee is about 1500. Other areas are not clear. Moreover, if there is no income, you can apply for a patent and ask for a fee reduction. If your annual income is less than 25,000 yuan, you can reduce it by 85%. This includes the application fee and the annual fee for the first three years, and the annual fee for the fourth year will be paid in full.

If you can write a case yourself, you can download the patent application form from China National Intellectual Property Administration online and fill in this form according to its example. Except where it is signed, it is in the form of a request for a patent for invention or utility model, an abstract of the specification, drawings, claims, specifications and drawings. If the fee is reduced, you must pay the fee reduction request. These forms were downloaded from China National Intellectual Property Administration's website.

If there is anything you don't understand, you can also go to the patent agency in this province to inquire. The phone number is also on China National Intellectual Property Administration's website. You can call for advice.
