When is the annual patent payment time? Who will tell us?

The annual patent payment time is generally paid within one month before the expiration of the previous year, and the expiration date of the payment period is the corresponding date of the application date of that year. For example, if the patent application date is 65438+1 October 1 in 2022, then the annual payment period should be between 202 1, February 1 and1October1. If the annual fee is not paid within the specified time, the patent right shall be terminated before the expiration of the time limit.
