Why is the number of patent applications of individual enterprises significantly higher than that of a certain year?

Grant a patent right to an application for a patent for invention that meets the requirements. The applicant should also go through the registration formalities on schedule and pay the annual fee for the current year, so that the application for a patent for invention can formally become an invention patent with various patent attributes. In order to encourage society's enthusiasm for invention and creation, most local governments in China provide special financial support to individuals and enterprises applying for patents, which can be inquired by local science and technology bureaus. Annual fee payment: the annual fee for the year when the patent right is granted shall be paid at the same time as the registration formalities, and the annual fee for the future shall be paid before the expiration of the previous year. The expiration date of the payment period is the corresponding date of the application date of the current year. This annual fee can be paid by the applicant himself or by us.
