Doom Creator Accused of Stealing Virtual Reality Tech, Taking It to Oculus

Well this sounds ugly, and bound to get uglier: John Carmack, the fellow gamers know best for helping birth Doom, and who left id Software last year to take a job as chief technology officer with Oculus Rift headset designer Oculus VR (who were in turn recently snatched up by Facebook for a cool $2 billion), has been accused by his former employer, ZeniMax, of purloining virtual reality secrets the games publisher claims belong to it, not Oculus VR.

ZeniMax Media, which also owns Bethesda Game Studios (The Elder Scrolls series and Fallout 3) and Arkane Studios (Dishonored) claims that Carmack was involved in “extensive VR research and development” during his tenure at ZeniMax, according to the Wall Street Journal. That, says ZeniMax, gives it dibs on “key technology used by Oculus to develop and market the Oculus Rift,” and thus the right to seek compensation.

According to the Journal, ZeniMax is staking its case on allegations that Carmack was in touch with Oculus VR founder Palmer Luckey before leaving ZeniMax, that Carmack received a prototype headset from Luckey, and that he made innovations to the headset, which he then demoed during a convention.

“ZeniMax’s intellectual property rights arise by reason of extensive VR research and development works done over a number of years by John Carmack while a ZeniMax employee, and others,” writes ZeniMax in a press statement (via Engadget). “ZeniMax provided necessary VR technology and other valuable assistance to Palmer Luckey and other Oculus employees in 2012 and 2013 to make the Oculus Rift a viable VR product, superior to other VR market offerings.”

The statement continues:

The proprietary technology and know-how Mr. Carmack developed when he was a ZeniMax employee, and used by Oculus, are owned by ZeniMax. Well before the Facebook transaction was announced, Mr. Luckey acknowledged in writing ZeniMax’s legal ownership of this intellectual property. It was further agreed that Mr. Luckey would not disclose this technology to third persons without approval. Oculus has used and exploited ZeniMax’s technology and intellectual property without authorization, compensation or credit to ZeniMax. ZeniMax and Oculus previously attempted to reach an agreement whereby ZeniMax would be compensated for its intellectual property through equity ownership in Oculus but were unable to reach a satisfactory resolution. ZeniMax believes it is necessary to address these matters now and will take the necessary action to protect its interests.

Oculus’s response? Balderdash: “It’s unfortunate, but when there’s this type of transaction, people come out of the woodwork with ridiculous and absurd claims,” an Oculus VR representative told the Journal. “We intend to vigorously defend Oculus and its investors to the fullest extent.”

And Carmack himself has weighed in on Twitter:

That’s all we know so far, which is to say that it’s best to stay off the playing field just now in terms rallying for one side or another, since the only folks who know who’s telling (or twisting) the truth are John Carmack, ZeniMax and Oculus VR.
