Derwent World Patents Index (DWPI)

Capturing better insights from global patent publications is easier than ever.

For 60 years, Clarivate has combined the knowledge of subject matter experts with a big data approach to provide the premier source of global patent data, the Derwent World Patents Index. The DWPI team of 900+ editors analyzes, abstracts and indexes nearly 90,000 new patent publications every week.

R&D teams, IP professionals and over 40 national patent offices around the world rely on DWPI to help them find more relevant patents in less time.

Patent research to accelerate your innovation.

Capture more comprehensive, more relevant keyword search results
DWPI improved keyword search results by 79% compared to worldwide patent searches performed without DWPI on other patent search platforms.
Spend less time reviewing patent documents.
DWPI abstracts are written to clearly describe the patent’s novelty, use and advantage, making it easy for you to understand what a patent covers without having to read the entire document.
