Derwent World Patents Index (DWPI)

The world’s patent data: curated, enhanced and simplified.

Capturing better insights from the world’s patent publications is easier than ever.

For nearly 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.

  1. Capture more comprehensive, more relevant keyword search results
    DWPI improved keyword search results by 79% compared to patent searches performed without DWPI on other patent search platforms.
  2. 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.
  3. See an invention’s complete 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.

Find the right patents and capture the right insights.
