IBM has filed subpoenas demanding information from Microsoft, Hewlett-Packard, Sun Microsystems and BayStar Capital about their relations with SCO Group as part of its own defence in a long-running dispute over Linux code.
SCO sued IBM in 2003, claiming that the hardware giant had breached its intellectual property rights by using SCO’s version of Unix code in its distribution of Linux.
Now IBM is seeking any records or communications covering the way its rivals have used Unix code, royalties paid for Unix products, relevant software licensing agreements and other information about their relationships with SCO.
The detailed subpoenas request information relating to specific meetings and communications between named senior executives at the companies and SCO.
Venture capital firm BayStar has been targeted because of its investments in SCO. All four firms are to provide the subpoenaed information by 7 March.
