As for the numbering rules, this is very complicated, and no one can remember it, so I can only copy it to you. Hope useful to you
1. Numbering system of U.S. patent application number
Characteristics of application number:
(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, all kinds of 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 application number serial code 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
Used for unilateral review request.
95 is used for mutual recheck request.
It should be noted that the application serial number of 1 ~ 6 is common in the title page of American patent specification, such as APPLNo. : 1, application number: 600000. In recent years, the US 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 of the application number and six serial numbers of the application. If the number of digits is insufficient, it is filled with zeros, such as APPLNo. : 09/00000 1.
2. The document numbering system of American patent specification.
Characteristics of the number of submissions:
(1) Since 200 1, the U.S. Patent and Trademark Office has published two kinds of public specifications: an invention patent application and a plant patent application. The publication number consists of two parts: the four-digit publication year number and the seven-digit publication sequence number. If the number of digits is insufficient, make up with zero. It should be noted that the application for a patent for invention and the application for a patent for plants include re-published documents (A2, P4) and corrected documents (A9, P9), and all published documents are arranged in the order of serial number, such as US.
2006/0070 159 P 1，US 2006/0070 159 A 1 .
(2) Other patent documents are arranged according to their respective serial numbers, such as US 665432 1 B 1, US PP 12345 P2.
(3) Before 200 1, the patent documents published by the United States Patent and Trademark Office often used English abbreviations to indicate the types of documents, such as Des.456789, RE 12345. Since 200 1, the United States Patent and Trademark Office has fully adopted the patent document category identification code specified in WIPO standard ST. 16 "Recommended standard code for identifying different types of patent documents", but still retains the practice of using English abbreviations, abbreviations or initials to indicate the document category before the submission number, such as RE 12345 C 1.
