How many years should I pay the annual fee for the invention patent?

1. What is the annual fee for invention patents? The annual fee has nothing to do with the value of the invention itself, but with the type of patent and the year when the annual fee is paid. Among the three kinds of patents, the annual fee of invention patent is the highest, and the annual fee of utility model patent and design patent is the same. For example, the annual fee for the invention patent in the eighth year is 2000 yuan, while the annual fee for the utility model and design patent in the same period is 1200 yuan. For the same kind of patent right, the amount of annual fee payable is the same, and the amount of annual fee increases with the continuation of protection time, and a progressive system is implemented. For example, the annual fee for utility model and design patent is 2000 yuan in 600 yuan from the first year to the third year, 900 yuan from the fourth year to the fifth year, 1.200 yuan from the sixth year to the eighth year, and 2000 yuan from the ninth year to the tenth year. The amount of the annual fee shall be determined according to the year in which the patent right is granted. For example, if the application date of a utility model patent is March 1 day, 2000 and the authorization date is May 1 day, then the annual fee for the second year should be paid when the patent right is granted, not the annual fee for the first year. The annual fee for the third year is paid in the following year, and so on. Second, how to pay the patent annual fee In order to avoid the termination of the patent right due to the omission or wrong payment of the annual fee, the patent law stipulates a grace period of six months. In other words, the annual fee and late payment fee are allowed to be paid within 6 months from the date when the annual fee expires. If the annual fee and late fee are not paid in full within the grace period, the patentee will be notified to terminate his patent right and announced to the public. If the grace period is missed due to justifiable reasons or force majeure, the applicant may request the restoration of the patent right within two months after receiving the notice and within two months after the obstacle is removed, and pay the restoration fee to request the restoration of the patent right. Patent fees can be paid directly to China National Intellectual Property Administration, or remitted by post office or bank. The correct patent application number or patent number should be stated, as well as the name of the fees paid (such as annual fees and late fees). If the expenses are paid by the bank or post office, they should be paid in advance as far as possible. Can the obligation of the patentee to pay the annual fee be fulfilled by others? China National Intellectual Property Administration doesn't ask the source of fees when charging, so in practice, others are allowed to pay.
