I want to apply for a patent, which is a small invention that is beneficial to the convenience of life. Is there any professional who can provide me with helpful information?

Invention patent is 4200 yuan, utility model is 2000 yuan, and appearance patent is 1 100 yuan. Local governments have subsidies or incentives for patents. I'll help you write it in ten days, and the patent number will come down on the day you report to the patent office. The invention patent certificate will come down in about three years, and the protection period will be 20 years. The utility model and appearance patent certificate will come down in eight to ten months, and the protection period is ten years. Appearance patents need to be photographed from the front.
