AMD has issued a subpoena to Intel in regards to the anti-trust trial which isn't expected to begin until 2007:

The procedural move targets more than 15 computer makers and a dozen distributors and retailers that AMD believes may possess information related to its claims against Intel.

An AMD spokesman underscored that his company is not suing the companies. "AMD views these third parties as victims of Intel's misconduct and therefore hopes to obtain these documents in the manner least burdensome to them," he said.
