Derwent Chemical Patent Index

Increase the speed and accuracy of your chemical searches.

If you miss a vital patent, you could end up  on the wrong side of an expensive law suit. The Chemical Patent Index (CPI) enables you to conduct targeted searches of chemical patent data in the Derwent World Patents Index® (DWPI) – the most comprehensive database of value-added patent documents published in the world. Its powerful indexing systems and enhanced patent abstracts provide access to critical chemical patent records that may otherwise have been missed.

CPI data is also available through The Scientific & Technical Information Network.


… To be the preferred chemical company… we need a comprehensive view of the innovation landscape to plan the way forward for our product development and partnering strategy.
