FIZ Karlsruhe, Thomson Scientific Announce Availability of Enhanced Derwent World Patents Index® on STN®

30. October 2006

KARLSRUHE, GERMANY/ PHILADELPHIA, USA October 22, 2006 - Thomson Scientific, a business of The Thomson Corporation, and FIZ Karlsruhe announced today the launch of the enhanced version of Derwent World Patents Index® (DWPISM) on STN International, (The Science & Technical Information Network). DWPI from Thomson Scientific is the world renowned database of value-added patent information.

The DWPI database has been updated to offer the patent information searcher a broader view of global patenting activity. The enhanced DWPI database provides new value-add content and original patent data and a new two-part structure to facilitate access to the vast data found in DWPI.

"Together with our partner Thomson Scientific, we are delighted to launch the new Derwent World Patents Index file on STN", said Dr. Rainer Stuike-Prill, vice president Marketing and Sales, FIZ Karlsruhe. "STN customers will greatly benefit from the additional content and the new record structure, enabling even more precise searching and thus giving them greater insight into their areas of specific interest."

Specific new information that is available through the enhanced DWPI database includes:

  • Over 750,000 Documentation Abstracts (1995-1999)

  • Additional chemical structure indexing (Chemistry Resource) backfile

  • New first-level data, such as original patent titles and abstracts, full names of inventors and associated addresses, and patent agent information

  • Coverage of USPTO national patent data classifications

Additionally, DWPI database records now have a brand new two-part structure – Invention and Members. The Invention level comprises traditional DWPI content, such as patent family and enhanced abstracts. The Members level provides new additional information from each of the publications listed in the patent family portion of the patent record. This new structure is designed to make records easier to access and use.

Other enhancements include the removal of stop words, and SLART (Simultaneous Left and Right Truncation) is available in most text fields. The new sub-sections on each patent family member can be individually searched — providing a wealth of additional opportunities for more selective searches.

"Thomson Scientific is committed to supporting patent researchers worldwide, and with our partner, STN, we are pleased to offer this enhanced version of DWPI,” said David Brown, executive vice president of corporate markets, Thomson Scientific. "This enhanced file extends the functionality, content breadth and performance of the file, and strengthens the DWPI position as the world’s foremost patent resource.”
