As anounced in a previous "update", the Chinese Patent Office's (SIPO) "Patent Search and Service System" (PSS System) went online for public testing in April 2011. Previously, the "region & language" settings had to be modified in order to use this source properly on Western computers. With a system update relased in late June 2012, changing the settings is now no longer necessary. This source works best with Internet Explorer and Firefox browsers.
