Exploring Derwent World Patents Index® on New STN

The slides of the IPI ConfEx 2015 workshop Exploring Derwent World Patents Index® (DWPI℠) on new STN  are now available.  At this workshop attendees learned about the latest content and feature enhancements for DWPI on the new STN platform. The workshop provided expert tips and advice for searchers already familiar with DWPI and the Derwent Chemistry Resource (DCR) on STN, and also a helpful overview of the various features and benefits for those who were completely new to STN.
