The discovery relates to Intel's business dealings and sales transactions with customers in foreign countries. AMD is fishing for evidence that Intel forbid OEMs to buy from AMD and threatened retaliation if they did.

The US court decided months ago that it doesn't have jurisdiction over strictly foreign business dealings and that AMD can't claim damages if it was stopped from selling German-made processors to overseas accounts, but the special master sided with AMD on discovery and said it should have the scope to prove its claim that Intel is a monopoly and foreclosed AMD's chances of selling American-made products at home and abroad and foreign-made products to domestic accounts.

There's no guarantee that the discovery will be accepted as evidence and Intel intends to run inference to block what it can.

The suit is currently scheduled to go to trial in April of 2009, four years after it was filed.
