I know the name - they were co-counsel on a case I did some litigation support work a few years back.

The fact that they represent Mircosoft in one issue doesn't necessarily mean that MS is supportive of anti-Acacia litigation, although I cannot see how they would not like to see them crushed like a bug on somebody else's dime.

However, any general research on prior art conducted by the firm can be used by the firm however they want. There are restrictions on how work done by others provided to the firm by MS or other outside MS counsel can be used, but even that can sometimes point people in the right direction.
