AMD is no doubt hoping to reach an out of court settlement similar to that of its rival nVidia, after chip design company Opti filed a patent-infringement lawsuit against AMD. nVidia fought a similar case with Opti earlier this year.

Opti, which licenses intellectual property for technology used primarily by PC and chip manufacturers, claims that AMD has infringed three of its patents for a technology known as Predictive Snooping of Cache Memory for Master-Initiated Accesses.

The complaint alleges that AMD has infringed the patents by making and selling CPUs (central processing units) and core logic products using Opti's predictive snooping technology.

Opti filed the lawsuit with the US District Court for the Eastern District of Texas. It has asked for a jury trial and is seeking an injunction and monetary relief.

AMD, in Sunnyvale, California, could not immediately be reached for comment.

Opti, based in Mountain View, California, filed a similar lawsuit in 2004 against nVidia, which agreed to a settlement earlier this year.
