  Nowadays, SIPO not only promotes the electronic publication of patent information on the Internet, but also keeps the traditional medium of paper.

  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 TIFF formats once a week with the bibliographic data, abstracts and representing drawings, legal status, indexes, etc.
Patent specifications
Specifications of inventions published, granted and utility models granted are published together with patent gazettes once a week in TIFF formats, with claims, descriptions and drawings.
Patent certificates
The patent certificates 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 and HDD.

  Word processing and office automation
  The paper filings are scanned and converted into the electronic image data for subsequent procedures. The bibliographic data are manually collected twice, and then the two sets of data are compared automatically to find the differences so as to eliminate the clerical errors.

  (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 of patent gazettes in TIFF format edited and typesetted are published in paper, optical disks and 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 accessible on the Internet.
