A US judge heard arguments from Novell and SCO in the "slander of title" case brought by SCO against Novell last January.
Lawyers for SCO and Novell argued two motions during the proceedings, each lasting about 30 minutes, according to Bruce Lowry, a Novell spokesman.
Arguments were made over a SCO motion to move the case back to the state court where it had originally been filed, and a Novell motion to dismiss the case.
"We said that he shouldn't dismiss the case, that there is a lot more to be heard still; a lot of evidence to bring forward," said Blake Stowell, a SCO spokesman.
Judge Dale Kimball said he would take the arguments under advisement. No timeline was set for when a ruling on the motions would be made.
The case is a feud over which company owns the copyright to the Unix System V operating system.
Novell sold certain rights to its Unix business in 1995, but claimed that it retained copyright over the Unix code.
SCO, which eventually acquired the Novell rights, maintained that it now owns the Unix copyright, and has filed a $5bn lawsuit against IBM connected to this claim.
