Beijing Wuyi International Intellectual Property Answers, \x0d\ 1. U.S. patent number format: \x0d\\x0d\ The United States uses a series code, a patent application publication number or an approval number, and an application publication number format It consists of a 4-digit year serial number. \x0d\\x0d\For example: 20060100198, 20050158320. The format of the approval authorization number consists of 1-7 digits. \x0d\\x0d\For example: 5575155, 0123456. No category code is added. \x0d\\x0d\In addition, the validity period of U.S. patents is the same as that in China. It is also calculated from the filing date, 20 years for inventions and 10 years for designs. However, there are no utility model patents in the United States. \x0d\\x0d\ 2. Characteristics of U.S. patent numbers: \x0d\\x0d\ (1) The U.S. Patent and Trademark Office divides various applications into several major categories (such as: invention patent applications, design patent applications, provisional patent applications etc.), various application cycle numbers. The age span of the cycle period varies and is determined by the number of applications. Generally speaking, the patent application numbers of various types are arranged continuously from 1 to 999999 in each cycle, and the cycle starts again and again. \x0d\\x0d\ (2) To distinguish application numbers with different cycle periods, use application number serial codes. This is very important for database searches of US patent documents. \x0d\\x0d\ (3) The application number series code is also used to indicate the application type: \x0d\\x0d\01-28 is used for invention and plant patent applications, and the two are mixed, for example, 08/101840 is a plant The patent application number, 08/101841, is an invention patent application number. So far, invention patent applications have entered the 11th cycle. \x0d\\x0d\29 For design application\x0d\\x0d\60 For provisional application\x0d\\x0d\90 For unilateral re-examination request\x0d\\x0d\95 For bilateral re-examination request\ x0d\\x0d\It should be noted that what is commonly seen on the title page of U.S. patent specifications is a 1 to 6-digit application serial number, such as Appl. No.: 1, Appl. No.: 600 000. In recent years, the U.S. Patent and Trademark Office has begun to publish the application number serial code on the title page of the patent specification, and stipulates that the patent application number consists of a two-digit application number serial code and a six-digit The application sequence number consists of two parts. If there are insufficient digits, zeros will be used to fill in the digits, such as Appl.No.: 09/000001. \x0d\\x0d\ 3. Characteristics of the document numbering of U.S. patent specifications: \x0d\\x0d\ (1) Since 2001, the U.S. Patent and Trademark Office has begun to publish two types of disclosure specifications for invention patent applications and plant patent applications. The publication number consists of two parts: a four-digit document publication year number and a seven-digit document publication sequence number. If there are insufficient digits, zeros will be used to fill in the digits. It should be noted that invention patent applications and plant patent applications include the re-publication documents of the application (A2, P4) and the correction documents of the application (A9, P9). All published documents are arranged in serial number order, such as US\x0d\ \x0d\2006/0070159 P1, US 2006/0070159 A1. \x0d\\x0d\ (2) Other patent documents are arranged in the order of their respective document number series, such as US 6654321 B1, US PP12345 P2. \x0d\\x0d\ (3) Before 2001, the United States Patent and Trademark Office often used English abbreviations before the document number to indicate the type of patent documents published by it, such as Des. 456789, RE 12345. Since 2001, the U.S. Patent and Trademark Office has fully adopted the patent document type identification codes specified in WIPO standard ST.16 "Recommended Standard Codes for Identifying Different Types of Patent Documents" in the patent documents it publishes, but it still retains the document number. The previous practice of using English abbreviations, abbreviations or initials to indicate document types, such as RE 12345 C1, PP12345 C1, D654321 C1. \x0d\\x0d\ 4. U.S. patent document description item identification code \x0d\\x0d\Patent document description item, referred to as the description item.

A description item originating from general books and documents, used only for patent document descriptions, and is a feature indicating patent information published on the title page of a patent specification. The International Cooperation Committee on Information Retrieval between Patent Offices of the Paris Union (ICIREPAT) has developed a unified identification code for patent document description projects. This enables the recording of patent documents to achieve an internationally unified standard. \x0d\\x0d\The specific meaning is as follows: \x0d\\x0d\10Document mark\x0d\\x0d\ (11) Document number (patent number) \x0d\\x0d\ (12) Document category\x0d\\ x0d\(13) Document type code developed in accordance with WIPO standard ST.16\x0d\\x0d\(15) Information on patent amendments\x0d\\x0d\(19) The country or institution that publishes patent documents\x0d\\ x0d\20Application data\x0d\\x0d\ (21) Application number\x0d\\x0d\ (22) Application date\x0d\\x0d\ (23) Other dates (including exhibition registration date, submission of temporary instructions, complete submission Instruction registration date)\x0d\\x0d\ (24) Effective date of ownership\x0d\\x0d\ (25) Language of original application for publication\x0d\\x0d\ (26) Language of application for publication\x0d\\x0d\ 30Priority data\x0d\\x0d\(31) Priority application number\x0d\\x0d\(32) Priority application date\x0d\\x0d\(33) Priority application country or organization\x0d\\x0d\40 Documents The date of public disclosure\x0d\\x0d\ (41) The date when the specification of the unexamined and unapproved patent is made available to the public for viewing or copying. \x0d\\x0d\ (42) The date on which the description of the patent that has been reviewed but has not yet been approved is made available to the public for viewing or copying is accepted. \x0d\\x0d\(43) The date of printing or similar publication of instructions for unexamined and unapproved patents. \x0d\\x0d\ (44) The date when the specification of the patent that has been examined but has not yet been approved is printed or published by a similar method. \x0d\\x0d\ (45) The date of printing or similar publication of the specification of the patent upon examination and approval. \x0d\\x0d\(46) The date of printing or similar publication of the patent claim. \x0d\\x0d\ (47) The date on which the specification of an approved patent is made available to the public for viewing or copying. \x0d\\x0d\ (48) The revised publication date of the patent document. \x0d\\x0d\50 Technical information\x0d\\x0d\ (51) International patent classification number, abbreviated as Int.Cln., the number in the upper right corner of Cl indicates the IPC version, such as Int.Cl3 indicates IPC Third edition. \x0d\\x0d\(52) National patent classification number\x0d\\x0d\(53) International decimal classification number\x0d\\x0d\(54) Invention title\x0d\\x0d\(55) Keywords\x0d \\x0d\(56) Published documents related to patent technology\x0d\\x0d\(57) Abstracts and patent claims\x0d\\x0d\(58) Scope of search subjects required during examination\x0d\ \x0d\60Other statutory reference items related to domestic patent documents\x0d\\x0d\ (61) Supplementary patent\x0d\\x0d\ (62) Divisional application\x0d\\x0d\ (63) Continued application\x0d \\x0d\(64) Re-announcement of patent\x0d\\x0d\(65) Earlier published patent document number related to the application \x0d\\x0d\(66) Filing of an earlier application superseded by the current document The date and application number are the later application filed after the rejection of the earlier application for the same invention. \x0d\\x0d\ (67) The filing date and application number of the patent application, or the authorized patent number, on which the current utility model application or registered utility model (or similar industrial property right, such as a utility certificate or utility innovation) was filed ). \x0d\\x0d\ (68) Basic patent number and/or patent document publication number for the purpose of the supplementary protection certificate.
