Innovative feature for professional searches: Derwent World Patents Index® with numeric property search feature
An enhanced version of Derwent World Patents Index® is now available. For the first time, the new implementation of DWPI on STN offers the patent information searcher a unique numeric property search feature that allows for searching the numeric values of 55 physical and chemical properties, found in the English text of all documents. Searchable properties and their respective base units comprise data like /SAR (Surface Area, m²), /CMOL (Molarity, Molar Concentration, mol/L), /DEN (Density, Mass Concentration, kg/m³), /MFR (Mass Flow Rate, Kg/s), /MM (Molar Mass, Molecular Weight, g/mol), /VOL (Volume, m³) and many more. The system will recognize 60 base units with 1,700 variants.
A search employing numerical property field codes will now be covering data from all fields comprising text in English language. A search for a physical property value will not only find hits in the text showing the exact value but will also include hits where the value is part of a given range (e.g. => s 10/cmol will find "at least 0.008 mol/l" or => s 45/deg will find "0 to 80 degrees"). Open ranges encountered in the database like ‘less than 100 degrees’ have been indexed as well and are routinely searched through. A search for a temperature in Kelvin units will also retrieve documents with the corresponding value (ranges) in Degrees Celsius or Degrees Fahrenheit units.
