A Silicon Valley company is suing Applefor using its patented technology in 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 licenses its intellectual property to personal computer manufacturers and semi-conductor device makers.
