STATS (Statistical approach) ü Identifies IPC entries most frequently referenced in the PATENTSCOPE database searched by particular terms. ü Statistical presentation of the search results is performed according to IPC subclasses and groups. ü Search by simple terms and multi-term (combination of simple terms separated by a space) in all patent collections of the PATENTSCOPE. 25
