Capturing the right insights from global patent publications is easier than ever
For over 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.
Comprehensive data, better results
DWPI improves keyword search results by 79% compared to worldwide patent searches performed without DWPI on other patent search platforms.
Save time reviewing patents
With DWPI, you get abstracts that clearly describe an invention’s novelty, use and advantage. This makes it easier for you to understand what a patent covers without having to read the entire document.
Explore global patent coverage
DWPI families go beyond priority relationships and group patents by invention, including non-convention equivalents and separating continuations that introduce new inventions into new families.
