A £5.5m legal defence fund is being set up to protect Linux users from lawsuits alleging copyright infringement that might be filed against them by the SCO Group.
Open Source Development Labs, a non-profit group set up in 2000 to accelerate the adoption of Linux, said it has already raised £1.6m from companies including Intel and IBM. The fund will be used to help pay the legal expenses of Linux users which have been or might be sued by SCO.
Last month, SCO began sending out written notices to its 6,000 Unix licensees requiring them to certify that they are in full compliance with their Unix source-code agreements and are not using Unix code in Linux.
"OSDL is responding to a call for leadership on this issue," said its chief executive officer Stuart Cohen. "This fund sends a clear message that OSDL, [and] others throughout the Linux industry, will stand firm against legal threats levied by the SCO Group."
SCO said the defence fund would not affect its claims about abuse of its intellectual property in Linux or its claims for compensation.
