AMD wins first battle in MMX lawsuit with Intel

A US federal judge has denied Intel's request for a temporary restraining order against Advanced Micro Devices in a trademark lawsuit over the MMX chip moniker. The ruling lets AMD continue to use the MMX term in its advertising and promotional materials for the AMD-K6 processor. Cyris, meanwhile, has chosen to settle with Intel over the same issue.

A US federal judge has denied Intel's request for a temporary restraining order against Advanced Micro Devices in a trademark lawsuit over the MMX chip moniker.

The ruling lets AMD continue to use the MMX term in its advertising and promotional materials for the AMD-K6 processor, the Sunnyvale, California-based chip maker says.

AMD will now formally announce the new chip family, its first to incorporate the MMX multimedia instruction set developed by Intel.

"We believe the term MMX belongs to the public domain and that it is commonly

understood to be a shorthand reference to multimedia extensions," says Thomas McKoy, AMD vice president and general counsel.

The court battle will continue, however. Intel is scheduled to present its arguments for a preliminary injunction to the court on April 29.

"We are confident that we can demonstrate to the satisfaction of the court that Intel is not entitled to trademark protection for the term MMX," says McCoy.

In a related news, Cyrix Corp. yesterday announced that it has settled its lawsuit with Intel over the MMX trademark, under terms that will let the Texas-based company and its customers use the MMX trademark for its forthcoming M2 processor, without fear of litigation.

Intel last month filed the trademark infringement suit against AMD and Cyrix in the US District Court in Delaware, seeking a temporary and permanent injunction against both companies, as well as unspecified fees and damages.

Intel officials could not be reached for comment.
