China: Recent enhancements of SIPO’s PSS System

Désolé. Actuellement, cette page n'existe pas en français.

Recently, the Chinese Patent Office (SIPO) has started to provide access to the full text data of Chinese patents and utility models via its "Patent Search and Services System" (PSS). Together with the bibliographic information, full text data can now be displayed on the screen by clicking on a separate tab. As before, users may also download original documents and retrieve English machine translations via an integrated tool.

Furthermore, in addition to the existing Chinese and English versions, additional search interfaces have been launched in German, French, Spanish, Portuguese, Japanese, Arabic and Russian languages.

SIPO's PSS System gives public access to Chinese patents, utility models and designs from 1985 onwards. In addition to bibliographic data, original documents, full text data and English machine translations, English legal status information, citations and information on patent families can be retrieved. For access to most of this data, free registration and login are required.

Step-by-step search guides which explain in detail how to use this platform are available on the EPO's Asian patent information webpages. For further questions, please contact
