(1) Patent number (application number) before June 20031:
The identification of counterfeit patents can be judged according to the patent marks marked on the goods, such as the patent number or the words "counterfeit patented products will be investigated". The patent number is composed of the Chinese phonetic alphabet "zL" written before the patent application number, and consists of 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; "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 check code of the computer. Is the remainder obtained by sequentially multiplying the first eight digits by 2, 3, 4, 5, 6, 7, 8 and 9, and then adding their products and dividing them by 1 1. When the remainder is 10, the remainder is represented by X. For example, the patent number is ZL92 1 14808.9, that is, the patent is 14808 invention patent applied in 1992, where 9 is obtained as follows: 9 */kloc.
In any of the following circumstances, it can be identified as a counterfeit patent: ① the patent number is incomplete; 7. The first two digits of patent number are less than 85; ② The third digit is a number other than 1, 2 and 3; ④ One digit after the decimal point is inconsistent with the result obtained by the above calculation method; ⑤ The number before the decimal point exceeds eight digits; ⑥ The patent category does not match the commodity. In addition, you can check the legal status of the patent to further verify the authenticity of the patent. For example, a patent that is invalid due to the termination or expiration of the fee or is regarded as giving up the patent right, and continues to mark the patent mark on the goods is also regarded as a counterfeit patent.
(2) Patent (application) number after 65438+2003 10: * * is represented by twelve Arabic numerals: the first four digits represent the year of patent application, and the fifth digit represents the patent type (1 represents the invention patent application, 2 represents the utility model patent application and 3 represents the design patent application; 8 denotes the PCT invention patent application that entered the national stage in China; 9 denotes the PCT patent application for utility model that entered the national stage in China), and the 6th to 12 digits indicate the serial number of the application. For example, 2003 10034567 indicates that it was an invention patent application in 2003, with the serial number of 0034567. Here's a method to identify the true and false patent number/application number (the necessary but insufficient conditions are seldom known, so it is quite effective to identify the true and false): Take the patent 200320 102 194.3 as an example. First, you are related to 2, 3, 4, 5, 6, 7, 8, 9, 2 and 7 respectively. When the remainder is 10, the check code is x.
