How to interpret the format meaning of American patent number?

Beijing Wuyi International Intellectual Property Solution, \x0d\ 1. U.S. patent number format: \ x0d \ x0d \ The United States consists of serial number, patent application WeChat official account or authorization number, and WeChat official account application format is 4-digit year serial number. \x0d\\x0d\ For example: 20060 100 198, 20050 158320. The format of the authorization number consists of 1-7 digits. \x0d\\x0d\ For example: 5575155,0123456. No category code. \x0d\\x0d\ In addition, the validity period of American patents is the same as that of China, which is 20 years from the date of filing, and the design is 10 year, but there is no utility model patent in the United States. \ x0d \ x0d \ II。 Features of U.S. Patent Number: \ x0d \ x0d \ (1) The U.S. Patent and Trademark Office divides various applications into several categories (such as 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. \x0d\\x0d\(2) In order to distinguish the application numbers in different periods, the application number series code is used. This is very important for the database retrieval of American patent literature. \x0d\\x0d\(3) The serial number of the application number is also used to indicate the application type: \ x0d \ \ x0d \ 0 1-28 is used for invention and plant patent application, and the two are mixed, for example, 08/10/840 is the plant patent application number. At this point, the invention patent application has entered the cycle of 1 1. \x0d\\x0d\29 is used for design application \ x0d \ x0d \ 60 is used for temporary application \ x0d \ x0d \ 90 is used for unilateral review request \ x0d \ 95 is used for both parties' review request \ x0d \ x0d \ Note that the number is: 1. 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. \x0d\\x0d\ III。 Document number characteristics of American patent specification: \x0d\\x0d\( 1) Since 200 1, the United States 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 sequence of serial numbers, such as US \ x0d \ x0d \ 2006/0070159p1,US2000. \ x0d \ x0d \ (2) Other patent documents are arranged according to their respective serial numbers, such as US 665432 1 B 1, US PP 12345 P2. \ x0d \ \ x0d \ (3) Before 200 1 year, the patent documents published by the United States Patent and Trademark Office often used English abbreviations to indicate the document type before the contribution number, 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. \ x0d \ x0d \ IV。 American Patent Document Description Item Identification Code \ x0d \ x0d \ Patent Document Description Item, referred to as Description Item for short. Descriptions from general books and documents are only used to describe patent documents, which are the characteristics of patent information disclosed on the title page of patent specification. The International Cooperation Committee for Information Retrieval between Patent Offices of Paris Union (ICIREPAT) has formulated a unified identification code for patent document description projects. As a result, the description of patent documents has reached the international unified standard. The specific meaning of \ x0d \ x0d \ WIPO is as follows: \ x0d \10 document mark \ x0d \ (1 1) document number (patent number) \ x0d \ x0d \ (.
