AMD seeks Microsoft documents in Intel case

AMD took another step in its antitrust suit against Intel Corp. on Thursday by filing a subpoena for documents from Microsoft Corp.

AMD has taken another step forward in its antitrust suit against Intel by filing a subpoena in US District Court in Delaware for documents held by Microsoft.

AMD has charged that Intel uses its overwhelming 86 per cent market share in the microprocessor market to intimidate computer makers and retailers from buying AMD chips by threatening to withhold illegal rebates.

To prove its case, AMD has been trying to obtain documents from 32 companies that do business with Intel, including computer makers like HP and Dell as well as retailers like Best Buy and Circuit City.

Many of those companies agreed to supply documents when they received a subpoena, while others were fighting in court.

A Microsoft spokesperson said the company planned to comply.

"Microsoft is not a party to this lawsuit, but we anticipate that both sides will be seeking documents and other evidence from Microsoft and many other participants in the PC industry. We will work with the parties in this case to respond to reasonable requests for documents and information," she said.

Intel was not immediately available to comment on this story.

According to court documents, AMD is seeking information relating to 64-bit microprocessors, product comparisons between Intel and AMD, and any discussion of marketing arrangements involving the three companies.

The subpoena sought the same kind of documents that AMD had already requested from other companies, AMD spokesperson, Michael Silverman, said.

To date, AMD has subpoenaed a total of 32 companies in its lawsuit, which began in June 2005.

AMD alleges that Intel has maintained a monopoly in the x86 microprocessor market by using exclusionary business tactics that prevent its customers from dealing with AMD.
