Chuck Mulloy, a spokesperson for Intel, said the redactions in the public documents protect the company's trade secrets and AMD is trying to use the latest filing to drag as many witnesses into court as possible to provide depositions in the case.

In its own court papers, which are also redacted at points, Intel contends that the chip business is competitive and that AMD and its processors have not provided the technical capabilities required by the world's top PC and server vendors. AMD has not gained market share due to the marketplace itself and Intel's ability to deliver products that its vendor partners wanted, Intel argued.

"In an industry with large, powerful customers, whose purchases are often measured in the hundreds of millions, and in some cases billions, of dollars, competition is often bruising," Intel's document said. "Both Intel and AMD engage in vigorous persuasion and negotiation to convince customers to align their products with the suppliers' offerings. In the face of this intense competition, AMD is seeking a rule that would require a successful competitor like Intel to pull its punches and not compete aggressively on price."

Many of the same arguments against Intel have shown up in various antitrust cases worldwide, including the recent actions by the European Union. Earlier in 2008, the New York Attorney General's Office opened an investigation into Intel's practices and cited some of the same business tactics that the chip maker allegedly engaged in against AMD.

The next hearing before Special Master Vincent Poppiti and presiding Judge Joseph Farnan is scheduled for June.
