What's the difference between the patent number of the United States and that of other countries?

(1) The United States Patent and Trademark Office classifies various applications into several categories (for example, invention patent applications, design patent applications, temporary patent applications, etc. ), each application cycle number. The age span of the cycle is different, which is determined by the number of applications. Generally speaking, various patent application numbers are arranged continuously from 1 to 999999 in each cycle, and the cycle is repeated.

(2) In order to distinguish the application numbers in different periods, the serial number of the application number is used. This is very important for the database retrieval of American patent literature.

(3) The serial number of the application number is also used to indicate the application type:

0 1-28 is used for invention and plant patent application, and the two are mixed. For example, 08/ 10 1840 is the plant patent application number, and 08/1kloc-0/841is the invention patent application number. At this point, the invention patent application has entered the cycle of 1 1.

29 for design applications

60 for temporary applications

90 is a unilateral review request.

Require both parties to re-examine.

It should be noted that the application serial number of 1 ~ 6 is common in the title page of the US patent specification, such as Appl. Number: 1, application number: 600 000. In recent years, the United States Patent and Trademark Office began to publish the serial number of the application number in the title page of the patent specification, and stipulated that the patent application number consists of two serial numbers and six application serial numbers. If the number of digits is insufficient, zero should be filled, for example, the application number is 09/00006544.
