Games company ZeniMax successfully sued Facebook-owned Oculus for $500 million earlier this year, and now it has a new target in sight: Samsung. The company has filed a new lawsuit over Samsung's Gear VR headset, claiming that "Samsung knowingly profited from Oculus technology that was first developed at ZeniMax, then misappropriated by Oculus executive John Carmack," reports The Verge. From the report: Carmack, whose company id Software was acquired by ZeniMax in 2009, was one of the driving forces behind the Gear VR. While the headset was released by Samsung, it's described as "powered by Oculus," with heavy software optimizations developed by Carmack. But the lawsuit alleges that Carmack owed much of his success at Oculus to software he developed as part of a team at ZeniMax. Among other things, the Texas court filing claims that Carmack secretly brought Oculus (and former ZeniMax) employee Matt Hooper into id Software's offices to develop an "attack plan" for mobile VR, which Oculus would later take to Samsung. The Samsung Gear VR was also built on some of the same code as the Oculus Rift, which was the subject of ZeniMax's earlier lawsuit. ZeniMax's basic argument is that Samsung would have been aware of the lawsuit against Oculus, which was filed during the initial development of the Gear VR. But "Samsung continued to develop the Gear VR with full knowledge of ZeniMax's allegations and without obtaining any right or permission from ZeniMax to use any of its copyrights or other confidential information." The new lawsuit officially accuses Samsung of copyright infringement for using ZeniMax VR code in the Gear VR, as well as trade secret misappropriation, unfair competition, and unjust enrichment.
