Every week, the US Patent Office publishes an XML data feed of various patent data including companies, inventors, classifications, and more. Over at Typologies.org, they’ve taken this data and assembled it into an interactive visualization and exploration tool that does a great job of showing some fascinating trends. You can click on any of the icons (shown above) and then see a great graph layout of how various categories interconnect.
