II. Matters concerning the generation, reproduction, distribution and use of primary and secondary sources of patent information
• Publishing, printing, copying (main types of publications of the Office in the field of patent information, etc.)

Nowadays, SIPO not only promotes the electronic publication of patent information on the Internet, but also keeps the traditional medium of paper. In these two ways, we provide patent information to government agencies, research institutions, industry and the general public.

• Main types of announcements of the Office in the field of patent information

Patent gazettes

Patent gazettes for inventions and utility models are published in paper and PDF formats once a week with the bibliographic data, abstracts and figures, legal status, indexes, etc.

Patent specifications

Specifications of inventions published, granted in TIFF formats and utility models are published together with patent gazettes once a week, with claims, descriptions and drawings.

Patent certificates

The patent certificates and their duplicate copies for inventions, utility models and designs are issued periodically.

• Mass storage media used (paper, microforms, optical storage, etc.)

The above-mentioned documents are stored in the medium of DVD.

• Word processing and office automation

The paper applications are scanned and converted into the electronic image data for the use of following procedures. The bibliographic data are collected manually twice, and then the two sets of data are compared automatically to find the differences so as to eliminate the clerical errors.
The bibliographic data of electronic filings is extracted from the applications automatically.
Prior to the generations of the gazettes, specifications, certificates, the bibliographic data is collated and corrected manually again.

• (New) techniques used for the generation of patent information (printing, recording, photocomposing, Optical Character Recognition (OCR), etc.)

Patent gazettes

By using electronic scanning and Optical Character Recognition (OCR) technologies in the data processing, the documents in PDF format after editing and typesetting are printed into patent gazettes and saved on the Internet.

Patent specification

Image files in TIFF format are generated by scanning, and after content selection and layout design the files are printed into pamphlets of specifications by using digital printing equipments and saved on the Internet.

III. Matters concerning abstracting, classifying, reclassifying and indexing of technical information contained in patent documents
• Abstracting, reviewing, translating

SIPO provides translation service from Chinese to English. The computer-aided translation workload in 2007 was over 28 million Chinese words of abstracts and nearly 7 million Chinese words of titles, applicants and inventors, all of which were from domestic applications.

• Classification1, preclassification2 (if applicable), and reclassification3 activities; Classification system used, e.g., International Patent Classification (IPC), other classification systems(please indicate whether or not patent documents are classified by your Office and, if so, which classification system is used)

The International Patent Classification (IPC) advanced version is adopted by SIPO to conduct the classification for applications of inventions and utility models.
In the pre-classification phase, the initial broad classification symbols (usually the IPC subclass or group) are allotted to patent applications manually for routing said applications to appropriate classifiers in the classification team who allots one or more classification symbols according to the latest version of IPC; examiners verify one or more IPC symbols given by the classifiers, reconsider the classification for the granted patents after search and examination.
As a new version of the IPC enters into force, SIPO will reconsider the related documents and usually perform the reclassification.

• Coordinate indexing (domestic deep indexing systems, keyword indexing)

Titles, abstracts and main claims of inventions published, granted and utility models granted since 1985 are indexed with keywords, which are used in the present China Patent Retrieval System (CPRS).
Patents related to the Traditional Chinese Medicine(TCM) published since 1985 are deeply indexed, including the rewriting of titles and abstracts, IPC detailed classification, PHC classification, keywords indexing based on category fields, TCM formula indexing, etc, and all the data processed are translated into English.

• Hybrid system indexing

No activities.

• Bibliographic data and full-text processing
