AMD has served more than 15 companies with subpoenas this week as part of its anti-trust lawsuit against rival Intel.
Computer makers and various US-based distributors and retailers have been told to make available documents to AMD that will help Intel’s smaller chip rival build its case.
Retailer Dixons was among those issued with a subpoena earlier this year, when AMD announced it was taking Intel to court over alleged unfair competition in the processor market. Intel denies all the charges.
Among those issued with subpoenas this week were Dell, HP, IBM, Lenovo Group, Sun Microsystems, Gateway, NEC and parts of Fujitsu.
The case is not expected to reach court until 2007 at the earliest.
