A decades-old legal battle between Xinuos and IBM over Unix copyright has resurfaced, with Xinuos appealing a previous ruling. The lawsuit, which originated from a collaboration on an Itanium variant of Unix between 1998 and 2001, claims IBM misused copyrighted source code in its AIX, z/OS, and Linux products. Xinuos, which acquired the remnants of Santa Cruz Operations (SCO), initially included antitrust claims against IBM's acquisition of Red Hat, but these were dropped. The core copyright infringement claim is now being appealed after a judge previously deemed it time-barred. AI
