SCO's public relations director Blake Stowell said the licensing programme was "going forward" and denied reports that it was to be suspended in the face of IBM's counterclaim.
Stowell told users to expect a few surprises at SCO Forum, where attendees will be given the opportunity to view an example of the contested code. "There could be a rabbit pulled out of the hat at SCO Forum - you never know," he said.
Stowell said 900 companies have contacted SCO in the past two weeks, 300 of which were willing to buy a licence. As yet, the company has just one licensee, however.
Users who buy a licence are unlikely to get a refund even if SCO loses its cases against IBM and Red Hat. Stowell said the licensing issue is separate from the IBM case and "users would not take out a licence if they did not need to".
In its counterclaim document, IBM has disputed SCO's right to charge Linux users licence fees and accused SCO of infringing four IBM patents.
Stowell denied this and said IBM's claims were "suspect".
