http://www.derwent.com


Thomson Derwent Information http://www.derwent.com is a division of Thomson Scientific. The services Derwent provides are, in part, part of ongoing efforts to maintain access through one service provider [Derwent] to the information services which are available from the all the other divisions of Thomson Corporation http://www.thomcorp.com.

The Derwent Innovations Index (DII) http://www.derwent.com/innovationsindex/index.html is a web-accessible database that merges patent information from the Derwent World Patents Index http://www.derwent.com/worldpatentsindex/index.html with the patent citation information from the Derwent Patents Citation Index http://www.derwent.com/patentscitationindex/index.html. This unique data set is accessed through an interface, giving the ability to browse between patent records, without having to learn and remember search commands. DII is the first collaboration between Derwent and its sister company, the Institute of Scientific Information (ISI) http://www.isinet.com/. As well as being able to review citations associated with a particular patent, it is also possible to extend the search of scientific information through non-patent citation links to the ISI Web of Science.

A copy of the presentation on the Derwent Innovations Index (DII) is available for download at http://www.derwent.com/innovationsindex/dii/demos/DII.exe.
