Psystar, sued by Apple for trademark and copyright infringement, has prepared its response to Apple's complaint. Psystar will claim that Apple is engaging in anticompetitive practices and will counter sue.

According to owner Rudy Pedraza, Psystar will counter sue under the Sherman Antitrust Act and the Clayton Antitrust Act and claim that when Apple ties its OS to it hardware, that is restraint of trade.

The response by Psystar will be filed on Tuesday afternoon according to CNET.

Mr. Pedraza will argue that their computers ship with a fully licensed copy of Mac OS X, unmodified, and that they depend on open source components of Mac OS X to enable a PC to run Mac OS X.

Some legal experts in this area had previously predicted that Psystar might try such an approach. Others question whether Apple would be considered to have monopoly status in this case.
