Carmack owned id Software, a company that was bought by ZeniMax in 2009. He is said to be responsible for the Gear VR headset in large part; it is described as being powered by Oculus.
The ZeniMax suit claims that Carmack gained his expertise as part of a ZeniMax team and used it to good effect at Oculus.
The suit says that in 2012, ZeniMax provided Oculus access to its VR-related IP under the terms of an NDA.
ZeniMax claims that at this time Oculus did not have a viabnle VR product.
"Oculus had a rudimentary headset that lacked fundamental VR functionality. To establish its VR business for its own commercial gain, Oculus breached the NDA, violated ZeniMax’s intellectual property rights, and exploited ZeniMax’s VR technology," the suit claimed.
"Samsung, which had desired to release a mobile VR headset and sell greater quantities of its mobile devices, was aware, or reasonably should have been aware, that Oculus acquired its VR technology through this breach of the NDA and in violation of ZeniMax’s intellectual property rights.
"Despite this awareness, Samsung nonetheless obtained and used ZeniMax’s VR technology from Oculus, without ZeniMax’s consent."
ZeniMax is seeking damages, profits from sales of “infringing works” and “use of trade secrets,” royalties, injunctive relief and punitive damages, plus lawyers' fees, court costs and interest.
