The USPTO has launched a new patent search system called the Global Patent Search Network (GPSN). Initial coverage includes Chinese published applications, patents, utility models from 2008 through 2011. Users can search patent documents in the
English or Chinese language and retrieve full-text
Chinese patents and machine translations.Additional Chinese patents and other national collections will be added over time.
I'm the librarian for research services in the Engineering and Science Library at Queen's University in Kingston, Ontario. I've been working with patent information since 1991, including seven years at the U.S. Patent and Trademark Office. I believe that the dissemination of patent information is a public good and should be promoted, especially in the education of science and engineering students.
