Accounting treatment of patent maintenance annual fee

The patent year is counted from the date of application, which has nothing to do with the priority date and authorization date, and is not necessarily related to the natural year.

The date of your patent application is 165438+20041October 5, and the first year of patent application is 165438+20041October 5 to 165438+2005/. The second year is from June 6, 2005 to June 5, 2004, and so on.

Patent annual fee is also called "patent maintenance fee". Generally speaking, the annual fee is increasing year by year. Paying the annual fee on time is an obligation that the patentee must fulfill. After the patent application is granted the patent right, the applicant shall pay the patent registration fee, the printing fee for the announcement and the annual fee for the year when the patent right is granted. The applicant for a patent for invention shall pay the application maintenance fee every year, excluding the year when the patent right is granted. Future annual fees shall be paid in advance within one month before the expiration of the previous year.
