Judge Joseph J. Farnan Jr. of the Delaware District Court told AMD's and Intel's lawyers to exchange disclosures this coming Thursday.
The procedure allows both parties to see what the other is holding in evidence to back up their claims, what witnesses they will call to support that evidence and so on.
AMD launched its legal action against Intel in June this year, and subsequently issued subpoenas against quite a few computer companies' US offices. Many firms have accepted the requests enshrined in the subpoenas, most notably Dell, which announced its willingness to comply last month. NEC, on the other hand, filed a whole series of complaints with AMD's demands.
