Bristol Technology Inc has named the witnesses it plans to call in the forthcoming antitrust trial against Microsoft Corp, scheduled to begin in Bridgeport, Connecticut from June 1. Bristol, which filed its suit last August, claims that Microsoft withheld the Windows source code it needed in order to continue its Wind/U Windows to Unix applications porting business. It says Microsoft is using its monopoly division to hold back the Unix market. Microsoft says the issue is just a contractual dispute. Bristol’s list includes three expert witness professors: Richard Langlois from the University of Connecticut, Lee Hollar from the University of Utah and William Barnett from Stanford University. Consultant Henry Stotsenberg is also on the expert witness list. Bristol will also field its co-founders, CEO and chairman Keith Blackwell, chief technology officer Ken Blackwell and senior VP, sales and marketing Jean Blackwell, as well as company president Chane Cullens and vice president of finance Mark Hrinya. The US Department of Justice’s antitrust case in Washington is currently in recess, and unlikely to resume until some time in April.
