The Derwent World Patents Index^® reloaded

The new Derwent World Patents Index^® (including WPINDEX, WPIDS, WPIX) has been released on April 03, 2022. The new implementation offers several enhanced search and display options, as well as content enhancements. Users only see minor changes to established DWPI features, so that existing search strategies are still valid in the new file. Chemical searchers need to be aware of the new DCR implementation and change their workflow accordingly.

The new DWPI has been significantly enhanced:

• The Derwent Chemistry Resource (DCR) is now a separate database with more powerful structure retrieval options and alert capabilities (SMARTracker). Crossover functionality is similar to DWPIM/DWPI and REGISTRY/CAplus.
• The Derwent Patent Citation Index (DPCI) is fully integrated in DWPI which broadens the scope of search capabilities.
  The database DPCI has been removed from STN.
• Claims coverage has been extended for major patent authorities.
