Apple is being sued by The Open Group, the company that claims ownership of the Unix trademark, for using the term “Unix” in conjunction with Mac OS X without a license, reports c|net. Apple has countersued and asked a judge to declare that the trademark is invalid, because the term Unix has become generic. “Though initiated nearly 18 months ago, the case has not yet gone to trial. According to a motion filed with the court Tuesday, both companies want to have an exchange of factual documents completed by August, with a trial sought for February… The case, filed in U.S. District Court in San Jose, Calif., has been winding its way through the courts, with the parties still in the discovery process. Months of mediation meetings ended without a settlement… The Open Group wants Apple to have Mac OS X undergo testing to certify that it complies with its standards for software bearing the Unix name, it also wants Apple to pay a fee.”
