What is the annual patent fee? How to pay

the fee is the fee that needs to be paid every year to maintain the validity of the patent right, starting from the year when the patent right is granted. Patents in China are divided into invention, utility model and design patents. The protection period of invention patent is 2 years, and that of utility model and design is 1 years. If you don't want to give up your patent right, you have to hand it over to the end of the protection period. It should be noted that the annual fee is calculated based on the application date, and it is regarded as one year from the application date of the previous year to the application date of the second year.

The annual patent fee should be paid in advance for the next year within one month before the patent application date.

payment method: the fee can be paid directly to the patent office or remitted through the post office.

all fees paid to the patent office shall indicate the correct application number, short name of the fee and the itemized amount, and those that are not indicated shall be deemed as not having gone through the payment procedures. So be sure to write down the correct application number, the short name of the fee and the itemized amount in the remittance message.

if the annual fee (except the annual fee of the authorized year) is not paid on time or the amount paid is insufficient, it can be paid back within six months from the date of expiration of the annual fee, and a late fee can be paid at the same time; The amount of the late payment fee shall be calculated by adding 5% of the full annual fee of the current year for each time exceeding the prescribed payment time of 1 month; When the overdue payment time exceeds the prescribed time limit but is less than one month, the overdue fine will not be paid. If the overdue period exceeds one month, the overdue fine will be increased by 5% of the annual fee, with a maximum of 25%. If it is not paid at the expiration of the time limit, the patent right shall be terminated from the date when the annual fee is paid.
