What is important for us is to find a comprehensive view of patent information that supports strategic decision-making and Derwent is helping us in this mission.

Sakae Nakamura IP Corporate Research & Development, Asahi Kasei Corporation

I’ve tried other AI powered patent search tools, and Derwent AI Search is hands down the best. With other patent search tools, you often need to review up to 50 or even 200 results to find the most relevant records. With Derwent AI Search, the most relevant records are at the top of the list, which helps me save a lot of time when evaluating patentability.

Susan Johnson Patent Agent and IP Researcher, Boston Scientific

You can feel the difference in the data. It’s clean, complete and gives you confidence. When I’m preparing for a client meeting, I don’t want to second-guess the results, and with Derwent, I don’t have to.
