Apple's right to restrict its proprietary operating systems and other software to its own proprietary hardware was upheld this week in a Circuit Court of Appeals ruling against Psystar, which began selling in 2008 a $399 Mac clone running Mac OS X.
When Apple sued and a court barred Psystar from selling the clones with Leopard pre-installed, it appealed. In its appeal, reports Ars Technica, Psystar attempted to keep the focus on what it described as Apple's anti-competitive practices.
Courthouse News Service reports that the three-judge panel in the Ninth Circuit Court of Appeals ruling disagreed that Apple had stifled competition or creativity with its copyright enforcement and that Apple's
... licensing agreement was intended to require the operating system to be used on the computer it was designed to operate, and it did not prevent others from developing their own computer operating systems.
The court did return a decision to seal documents in the case, which Apple had requested in order to protect proprietary information related to its copyright protection efforts, to the lower court for further consideration.
