Patent number and application number
Application number: When the patent applicant filed a patent application in China National Intellectual Property Administration, China National Intellectual Property Administration gave the patent application acceptance notice and patent application number.
Patent number: After the patent applicant obtains the patent right, the patent number on the patent certificate issued by China National Intellectual Property Administration is ZL (patent initials)+application number.
If you are applying for a patent, but the ZL letter is added before the application number, it belongs to improper use, and the administrative department for industry and commerce will investigate and deal with it according to law.
The meaning of patent number
According to Baidu's current understanding of users, the number of inquiries about patent numbers is increasing day by day, which proves that the inquiry about the authenticity of patent numbers is getting more and more attention, and the patent numbers in China are basically divided into the following two situations:
The patent number before 2002 is divided into four sections: for example, 97 10 1765.4. The first two parts indicate the year when the patent application was filed, such as "97" indicating 1997; The second paragraph consists of the third digit, indicating the type of patent application, and "1" indicates invention (if it is utility model "2", design "3", PCT invention patent application "8" and PCT utility model patent application "9"); The third paragraph consists of the fourth to eighth digits, indicating the serial number of this kind of application in the current year, for example, 0 1765 indicates the application in the current year 1765; The fourth paragraph consists of the ninth digit or symbol, which is a check bit automatically generated by the computer. It can be any number or character x between 0 and 9, such as "4" in this example.
Since 2002, the basic format of patent number is 20021000001.1,and the first paragraph of 2002 is 2002; The second paragraph consists of the fifth digit, indicating the application type; The third paragraph consists of the sixth to twelfth digits, representing the application serial number of that year (the increase in figures represents the increase in the number of applications in recent years, which is really gratifying and encouraging; On the other hand, it has indeed increased the workload and extended the time for the Intellectual Property Office); The fourth paragraph consists of the last digit or symbol, which is a check bit automatically generated by the computer and given by the computer.
The patent number of the patent that has been authorized, that is, the patent number on the authorization certificate issued by China National Intellectual Property Administration, is the application number in front of ZL. For example, the patent number granted by XXX is ZL2003 10 100002.
The patent number begins with the first letter "ZL" of its Chinese phonetic alphabet, followed by nine digits and a decimal point, in which the first two digits of the first eight digits of the decimal point indicate the year of patent application; The third digit indicates the category of the patent application.
1 is an invention, 2 is a utility model, and 3 is a design; The fourth to eighth digits represent the serial number of this kind of patent application in that year; The number after the decimal point is the computer check number, which is the remainder obtained by multiplying the first eight digits by 2, 3, 4, 5, 6, 7, 8 and 9 in turn, adding the sum of their products, and then dividing by 1 1. When the remainder is 10, it is represented by X.
For example, the drainage device of Yangzi refrigerator has patent number ZL8820 1465. X, namely 1465 utility model patent with patentNo. 1988, where the value of X is as follows: 8× 2+8× 3+2× 4+0× 5+ 1.
Therefore, if the following problems are found in the patent number marked on the goods, they can be identified as counterfeit patented products with forged patent numbers: ① the patent number is incomplete; ② The first two digits of the patent number are less than 85; ③ The third digit is a number other than 1, 2 and 3; (4) One digit after the decimal point is a number that is inconsistent with the calculation result of the calculation method introduced earlier.

Pure oxygen plasma oil-free ignition device has the right
ApplicationNo.: 20 14200226 18.3 Application Date: 2014-014.
A pure oxygen plasma oil-free ignition device is characterized in that the device sequentially comprises a plasma generator (1), an oxygen cyclone (2), a plasma generator nozzle (3), a premixing chamber (4), a high-temperature ceramic ring (5) and a premixing chamber nozzle (6) along the running direction of the plasma beam; Taking the axis of the plasma generator (1) as the center, the plasma generator (1), the oxygen cyclone (2), the cyclone blades (7), the high-temperature resistant ceramic ring (5) and the oxygen pipeline (8) are arranged in sequence from the inside out, and the axes of the above components are all on the same axis and distributed in a ring shape along the same axis. The device uses pure oxygen and plasma beam premixing to generate oxygen-enriched high-temperature body to ignite pulverized coal, which has the characteristics of high burnout rate, high central temperature, high flame temperature, high ignition energy of oxygen-enriched high-temperature body, strong adaptability and controllability of coal species, etc. Applicant:, Wang Qing, Xue Qinpu, Ren Address: No.21-8, Building A2, Yangjiapingbin New Century City, Jiulongpo District, Chongqing Inventor (Designer):, Jia Yi, Tian Guangxiang, main classification number: F23Q7/02(2006.0 1)I Classification number: F23Q. I F23L7/00(2006.0 1)I Legal Status 20 14-09-24 Authorized Note: This legal status information is for reference only, and a copy of the patent register must be obtained in China National Intellectual Property Administration to obtain real-time and accurate legal status information.
