ZeniMax Media and id Software have sued Oculus VR and its founder Palmer Luckey for allegedly stealing trade secrets and infringing on copyright, among other claims.
The rift began outside of court earlier this month when ZeniMax said that it’d been wronged by former employee and game development legend John Carmack. ZeniMax said Carmack, who became Oculus’ CTO in August of last year, did “extensive VR research and development” while still working at id Software, which is owned by ZeniMax.
Because of Carmack’s work, and a non-disclosure agreement signed by Luckey, ZeniMax felt it was entitled to a non-dilutable equity stake in Oculus, which would be worth a lot now that Facebook is buying it for $2 billion. Oculus previously disputed ZeniMax’s claims and pointed out that Carmack left Zenimax after it stopped investing in virtual reality games.
The lawsuit, as published by The Verge, claims that Carmack worked extensively on Oculus technology at id Software’s offices and even demonstrated the technology to the press there. ZeniMax also claims that it has been researching virtual reality since the 1990s and came up with a VR prototype for some of its major games, including The Elder Scrolls.
“As a result of their years of research, and months of hard work modifying the prototype Rift to incorporate ZeniMax’s VR Technology, Carmack and others at ZeniMax transformed the Rift from $500 worth of optics into a powerful, immersive virtual reality experience,” the lawsuit says.
Oculus has not yet responded, but with millions of dollars on the line, it’s safe to assume this is going to get messy.
Update: Oculus has responded with the following statement: “The lawsuit filed by ZeniMax has no merit whatsoever. As we have previously said, ZeniMax did not contribute to any Oculus technology. Oculus will defend these claims vigorously.”
