Compuware sued IBM for theft of trade secrets and copyright infringement of Compuware’s diagnostic tools used in the main frame environment. IBM counterclaimed for patent infringement. IBM developed and released competing software tools in ten months. The same tools had taken Compuware 25 years to perfect. The IBM software development team was based in Perth Australia. The case was tried to a jury in Detroit Michigan over five weeks. Using sophisticated time in motion studies, animations, and IBM development documents, the case settled with consideration of $400 million.
