The patent application number is an important content in the acceptance notice sent by China National Intellectual Property Administration to the patent applicant. It consists of eight digits plus a decimal point and a number (or the English letter X). The first two digits represent the year number of the patent application year, the third digit represents the category of the patent application ("1" represents the invention patent, "2" represents the utility model patent and "3" represents the design patent), and the last five digits represent the serial number of a patent application this year, and one digit after the decimal point or.
In order to solve the problem that the original 8-digit patent application number can't meet the increasing number of patent applications and make China's intellectual property industry standards in line with international standards, China National Intellectual Property Administration Standardization Committee revised the patent application number standard in the first half of 2003, and the 8-digit patent application number was replaced by the new 12-digit patent application number. The standard of patent application number was promulgated on July 4, 2003, and came into effect on October 0, 2003. The revised new patent application number is represented by the internationally accepted Arabic numeral 12, including the application year number, application category number and application serial number. In the order from left to right, the number 1-4 indicates the year when the patent application was accepted, the number 5 indicates the type of the patent application, and the number 6- 12 (***7) indicates the serial number of the application, indicating the relative order of accepting the patent application. Every Arabic numeral used in the patent application number is a decimal, and the number of years in the application number adopts AD year. In the next 20 years, there will be the coexistence of old and new application numbers. Applications for invention patents, utility model patents and design patents filed on or after June 10, 2003 are given and used according to the new patent application number standard. The patent application number given before September 30, 2003 (inclusive) will not be upgraded or replaced after June 65438+1 October1in 2003, and the original patent application number will continue to be used in various legal procedures stipulated in the Patent Law.
Only when the patent application is granted a patent right, the patent application number becomes the patent number.
