STN joins Thomson Reuters in celebrating a milestone anniversary for the most trusted and comprehensive value-added patent information source: while the Derwent World Patents Index is honoured for its 50th anniversary, STN can look at successful 20 years of DWPI on STN. And with the brand new implementation of DWPI in New STN Version One, STN paves the way for many more successful years of DWPI on STN.

Today, the Derwent World Patents Index provides access to information from more than 50 million patents, giving details of over 24 million inventions. Every week data is added from nearly 50,000 new inventions from 50 sources, including the five most important patent offices (China, Europe, Japan, Korea, US) and the World Intellectual Property Organization.

Both value-added content and first level data match with a sophisticated retrieval environment to obtain highly relevant search results. DWPI deep indexing is fully integrated and chemical structure searching is supported.
