Chinese Patent Documents from 1985 to 2012 Now Available
The Global Patent Search Network (GPSN) http://www.uspto.gov/patents/process/search/index.jsp
has now been updated to include additional coverage years from 1985 to 2012 and additional features to sort and narrow search results.
GPSN is available via the USPTO website enabling users to access Chinese patent documentation to conduct prior art searches. Users can search Chinese patent documents in English or the Chinese language.
Patent documents are available in full text Chinese and English machine translations. Also available are full document images of Chinese patents which are considered the authoritative Chinese patent document.
GPSN provides users with access to a new searchable foreign patent collection including machine translations that allow quick analysis of relevant prior art.
Users can now search documents including published applications, granted patents and utility models from 1985 to 2012. This collection will continue to be periodically updated with additional years of
coverage.
Although Chinese patent documentation is the first foreign collection to be part of GPSN, the USPTO anticipates expanding the network with collections from other foreign IP Offices.
