AMD, Intel Launch Subpoena Parade

Intel also has a motion pending with the judge, arguing that the court doesn't have jurisdiction over a good portion of the case, since all of AMD's microprocessor manufacturing operations are located overseas.

"There's no nexus in the U.S., so U.S. law does not apply," said Mulloy.

In addition to the AMD suit, 76 related class-action suits have subsequently been filed against Intel.

The judge has scheduled a meeting in September to consider a date for the trial, which many expect will take place sometime in 2008.

"We see no sign of Intel's anticompetitive behavior coming to an end," said AMD EVP of Legal Affairs Tom McCoy in a statement. "It is, therefore, not at all surprising that we've identified additional third parties that we believe may possess critical evidence of Intel's monopoly abuse, and we will continue to do so."

Shares of Intel were off 18 cents, or 1%, to $18.22 in recent trading. AMD shares slipped 0.8%, or 21 cents, to $25.21.
