Nathan Myhrvold, Microsoft chief technical officer, started at Microsoft in 1986 and was one of Bill Gates' close confidants. After leaving in 2000, Myhrvold formed Intellectual Ventures, often criticized as a patent troll for their methods of buying up patents and then profiting by either funding inventions, seeking licensing deals, or suing those using their IP.
Intellectual Ventures has collected nearly 70,000 "intellectual assets" on technologies ranging from nuclear power to camera lenses. It currently controls about 40,000 intellectual assets.
In addition, Myhrvold is a serious amateur cook and has authored a cookbook, "Modernist Cuisine," released in March 2011. He has also won first place at the Memphis barbecue championship and appeared as a guest judge on Top Chef.
