Description

As a part of the Web of Science search system, Derwent Innovations Index combines unique value-added patent information indexed from 75 patent issuing authorities in the Derwent World Patent Index (1963-present) with patent citations indexed from the Derwent Patents Citation Index (1973-present).

  • Search across clearly written patent titles and abstracts that highlight the novelty, use, advantage, and claims of each invention.
  • Search precisely using international patent classification codes or unique Derwent Class Codes.
  • Combines patents from multiple patent issuing authorities into a single patent family for an easy and complete discovery of each invention.
  • Monitor an invention's influence by navigating patent citations.
  • Compare patents using predictive metrics: powered by machine learning using historical outcomes across 150+ variables


For six major patent offices (U.S., Europe, PCT, Germany, Great Britain, and Japan), patents and articles cited by a given patent can be viewed, but not searched. Using the Advanced Search feature, citing patents can be viewed and searched by number, assignee, and inventor.

The Compound Search screen permits true substructure searching of chemical compounds via a drawing screen. Advanced searchers should make use of the detailed indexing provided in the International Patent Classification, Derwent Class Codes, and Derwent Manual Codes. For any result set, the most frequently appearing codes are displayed in the left-hand Refine Results column and can be used to further limit one's results. These codes can also be independently searched using the Search query screen. Careful use of the patent classes and special Derwent coding can greatly enhance the comprehensiveness of search results.

For more information, see the training video and the Quick Reference Card provided by the database producer. A very useful country-by-country guide to Derwent indexing policies, data formats, patent office procedures, and numbering systems used by different countries is available online under the page title, DWPI country/region coverage.  A historical, print 2001 edition of the information entitled Derwent Global Patent Sources: An Overview of International Patents located in the Lockwood Library Science & Engineering Reference Collection, call number T210 .D47 2001.

Please refer to the University Libraries Patent Databases Research Guide for a detailed overview of searching both free and UB subscription patent databases.
