Intergraph, the 40-year-old Alabama-based inventor of graphical workstations, an early adopter of what would now be called an industry standard combination of Microsoft NT on Intel, which at the time was a radical and ultimately money-losing move, and a company that sued Intel for patent infringement in one of the prettiest suits ever written, has been sold to Sweden's Hexagon AB for $2.13 billion. Intergraph, now just a software company, was taken private in late 2006 by investors led by Hellman & Friedman LLC, Texas Pacific Group and JMI Equity for $1.3 billion. Hexagon makes surveying equipment and measuring instruments. Intel paid Intergraph $675 million to settle claims that Pentium and Itanium infringed Intergraph's Clipper patents. At the time $675 million was still real money.
