To apply for a patent number, the frame number is the number of each car, which is equivalent to the ID card of the car.
The patent number is the number given when the patent right is granted, and it is a submission number. The submission number is the serial number compiled by each industrial property office when publishing patent documents (including public publication and reading and copying only).
The number of the patent number is of course meaningful. Take ZL20 10 1004567.7 as an example. ZL stands for patent, which is the abbreviation of patent pinyin. However, an application that has not yet obtained a patent cannot be marked with the word "ZL". 20 10 represents the year of patent application, 1 represents the patent type as an invention patent, if 2 represents a utility model patent, 3 represents a design patent 4567.
