London, UK - November 29, 2005 - Thomson Scientific today announced at Online Information 2005 that the enhanced version of Derwent World Patents Index® (DWPI^SM) will be released on the Dialog, STN International and Questel•Orbit online services in quarter one, 2006.

DWPI is the world’s leading database of value-added patent information. The enhancements are designed to ensure the database meets the requirements of the International Patent Classification (IPC), Version 8, which enters into force on January 1, 2006. All DWPI records affected by this reclassification will be updated and identified on an ongoing basis, enabling users to easily distinguish between original and re-classified IPC data.

The enhancements will also provide patent searchers with new information to make their searches even more effective, including:

• 750,000 documentation abstracts available for the first time in a text-searchable format.
• New family member sub-sections including data such as original patent titles and abstracts, plus extra bibliographic data such as full names of inventors and associated addresses, patent assignee addresses and patent agent information.

“Our implementation of the IPC reform within DWPI is intended to provide maximum benefit through allowing flexible use of IPC for search,” said Brian Tyler, executive vice president of corporate markets, Thomson Scientific, “and we are pleased to take the opportunity of the reload to deliver additional enhancements to searchers of Derwent World Patents Index.”
