A Silicon Valley company is suing Apple for using its patented technology in Apple Macintosh computers.

OPTi filed suit in US District Court for the Eastern District of Texas on 16 January, alleging that Apple violates three OPTi patents on what it calls 'predictive snooping of cache memory for master-initiated accesses'.

OPTi says Apple uses its patented predictive snooping technology without permission in its desktop, notebook and server computers and has asked for a jury trial to settle the dispute.

OPTi, of Mountain View, California, licenses its intellectual property to PC manufacturers and semiconductor device makers.
