Join our free webinar "Complex queries in the PATENTSCOPE search system" on November 25 or 27. Please register here:http://www.wipo.int/patentscope/en/webinar/ Due to an hardware problem on PATENTSCOPE servers, only national collections of Germany, United States, Japan, China and the PCT collection are currently available for searching. The other national collections should be back on line today or tomorrow. We apologize for the inconvenience caused.
