In China, there are three kinds of patent applications, namely, appearance patent application, utility model patent application and invention patent application. Generally speaking, you don't need to find an agency to apply for a patent, just apply for it yourself. If you want to apply for an appearance patent, you need to prepare a six-sided appearance view and fill in the necessary instructions of the appearance design, and then provide the application documents to China National Intellectual Property Administration. After submitting the application, you can get the acceptance notice in about a week, and get the relevant certificates for handling the formalities in 3 ~ 5 months, and then you have to pay the relevant fees, and then you can get the certificates. However, the application for a patent for invention shall be made after the application documents are submitted. You are in two stages: preliminary examination and substantive examination. The application process takes about three months. Therefore, it takes longer than applying for an appearance patent.
The general fee for an application for a patent for utility model and appearance is 500 yuan. If the company meets the exemption conditions, it can be exempted to 150 yuan, and individuals can be exempted to 75 yuan. The standard fee for applying for a patent is 3450, including the application fee and the substantive examination fee. If the company meets the exemption conditions, it can be exempted to 1070, and if the personal expenses meet the exemption conditions, it can be exempted to 560 yuan. In addition, if you ask the agency to increase the extra agency fee, then I suggest that you'd better not find an agency.
In a word, applying for a patent is a long process. There are huge economic benefits behind a technology. If your company can own many patented technologies, you can gain some advantages in the market competition. Finally, I hope my answer can help you.
