AMD is facing a patent infringement claim by chip design company Opti. Opti brought a similar case against chip company Nvidia in 2004, which was settled out of court earlier this year.
Opti alleges that AMD has infringed three of its patents for a technology known as Predictive Snooping of Cache Memory for Master-Initiated Accesses. The litigant claims AMD has wrongly used the technology in the manufacture of CPUs (central processing units) and core logic products.
Opti is seeking an injunction against AMD to prevent it using the technology at dispute, along with monetary damages. AMD has not so far responded to the lawsuit.
