AMD products accused of "Predictive Snooping"
OPTi filed a patent infringement lawsuit earlier today in the United States District Court for the Eastern District of Texas against AMD for infringement of three U.S. patents. The three patents at issue in the lawsuit are U.S. Patent No. 5,710,906, U.S. Patent No. 5,813,036 and U.S. Patent No. 6,405,291, all entitled “Predictive Snooping of Cache Memory for Master-Initiated Accesses.” The patents were awarded in 1995, 1997, and 2000, respectively.
The complaint alleges that AMD infringes the patents by making and selling CPUs and core logic products based on “Predictive Snooping.” OPTi has requested a jury trial in this matter. In its case against AMD, the OPTi is seeking an injunction and damages or other monetary relief, including pre-judgment interest and awarding OPTi's attorney fees.
In OPTi’s statement to the press, it acknowledged that lawsuits against chip makers such as AMD for patent infringement are a continuing part of the company's strategy.
OPTi went after NVIDIA in 2004, accusing it of infringing upon the very same patents as mentioned today, and eventually reaching a settlement where OPTi would receive up to $9 million.
