Ask a question about the annual patent fee.

The patent year can be determined according to your application date. For example, if you get the application number today, the day after tomorrow will be the first year. It takes a long time to examine patent applications, especially invention patents, so it is likely that you will have to pay an annual fee for the second or even third year when you authorize them. The annual fee is different. You can check which year's annual fee 1200, and then calculate it according to your application date.
