Apple v. Psystar Corp., maker of “Hackintosh” PCs
In April 2008, a somewhat shady and small company called Psystar began selling non-Apple computers running Apple's OS X Leopard operating system. Apple sued in July of 2008 alleging copyright misuse and, in a very interesting legal battle, emerged victorious in 2009. All told, Psystar only sold 768 of these “hackintosh” computers.
