According to a report in the The Salt Lake Tribune, a joint document filed in the US District Court in Salt Lake City by the SCO Group and IBM said legal issues remained to be resolved.
The judge who now presides over the dispute, David Nuffer, was thus likely to start moving to resolve the remaining issues, the Tribune said.
SCO sued IBM in March 2003, alleging that the latter had violated a contract it had with SCO by providing code owned by SCO to the Linux kernel. SCO also claimed that Linux was an unauthorised derivative of UNIX.
Novell got involved when it lodged a claim that it owned the copyrights to UNIX, hence making SCO's case untenable. A lengthy court battle ensued between SCO and Novell over who owned the copyrights to UNIX.
That went against SCO in March 2010, when a jury reaffirmed that Novell owned the copyrights to the UNIX. SCO sought a re-trial on the grounds that the jury's verdict was not in line with the evidence presented in the case.
That bid was turned down in June 2010 and at that stage it looked like SCO would have to give up its bid to sue IBM over contract violation.
