On 5 September 2012, the Chinese Patent Office (SIPO) released an English interface of its "Patent Search and Service System" (PSS), which can now be accessed via a direct link on SIPO's English website.
The English interface gives access to information on Chinese patents, utility models and designs from 1985 onwards. Useful features such as citation and family data and an English machine translation function are included. The source is free of charge, but registration is necessary for document download and other advanced functionalities.
