The US Patent Office has announced that Chinese patent documents can now be searched in English or the Chinese language using the Global Patent Search Network (GPSN), a service now available via the USPTO website.  The GPSN is a result of cooperative effort between the United States Patent and Trademark Office (USPTO) and State Intellectual Property Office (SIPO) of the People’s Republic of China.  The data available include full text Chinese patents and machine translations for published Chinese applications, granted patents and utility models from 2008 to 2011. Full document images of Chinese patents (considered the authoritative Chinese patent document) are also available. A GPSN Quick Reference Guide and FAQs are available at

The GPSN provides a potentially powerful tool for locating art for evaluating the patentability of new ideas or the validity of troublesome issued patents.
