Quartet Keeps You Organized

As a patent searcher, you may work on client matters, cases, or projects.  Quartet keeps you organized so you have everything related to the patent search in a single place and can find it easily, anytime.  With project folders, you can see everything related to an assignment from search strings to AI search results, family and legal status, custom highlights, saved results, and shared reports.

Finding Relevant Patent Families or Individual Patents is Easier than Ever

You can choose to perform a traditional search with the Boolean search engine or with the help of an AI search engine.  Both methods will work together to find relevant prior art that has been shown to deliver better prior art, more quickly.

The integration of both AI search and Boolean search simultaneously in Quartet, has helped me optimize my search strategies and perform analysis efficiently. Additionally, the seamless user interface design has made the steps of searching, reviewing, and reporting of results, streamlined.

Brian Davidson

I enjoy Quartet’s forward-looking approach, combined with their dedication to listening to user feedback to improve their system. I feel as though the team understands my needs and is willing to implement features to meet those needs. No other search system on the market allows you to effortlessly blend the best of traditional Boolean system searching with cutting-edge AI searching techniques.

Jonathan Skovholt

I love how Quartet makes it easy to quickly digest complex information like classification codes. A rare balanced system, Quartet is both intuitive to use while still being a powerful search system.
