by Jim Brown (FIZ Karlsruhe)
The Numeric property search feature in PCTFULL, AUPATFULL and CANPATFULL, offers exact value and range search options for over 30 physical and chemical properties in almost 400 units. Numeric values and their corresponding units are automatically extracted from the patent text, normalized and made available for searching. This session introduces this powerful search tool, and provides many practical search examples to demonstrate its use. Download slides
