UPDATE: John Carmack has commented on the allegations on Twitter saying:
No work I have ever done has been patented. Zenimax owns the code that I wrote, but they don't own VR.

ORIGINAL STORY: ZeniMax Media has accused id Software co-founder John Carmack of stealing technology belonging to the firm when he left to join Oculus Rift according to papers seen by the Wall Street Journal.
ZeniMax's lawyers claimed:
"It was only through the concerted efforts of Mr. Carmack, using technology developed over many years at, and owned by, ZeniMax, that [Oculus founder] Mr. Luckey was able to transform his garage-based pipe dream into a working reality."
In a statement, Oculus responded saying:
"It's unfortunate, but when there's this type of transaction, people come out of the woodwork with ridiculous and absurd claims. We intend to vigorously defend Oculus and its investors to the fullest extent."
In a lengthy statement to Engadget, ZeniMax commented:
"ZeniMax confirms it recently sent formal notice of its legal rights to Oculus concerning its ownership of key technology used by Oculus to develop and market the Oculus Rift. ZeniMax's technology may not be licensed, transferred or sold without ZeniMax Media's approval.
"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. 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 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."
The Bethesda-owner claims Carmack stole technologies he developed while at id software and are calling on Oculus to prepare a licensing agreement or prepare for legal action. ZeniMax also claims Oculus CEO Plamer Luckey "acknowledged in writing" that certain, unspecified technologies used by the firm belonged to ZeniMax but the company "was unable to reach a satisfactory conclusion" for compensation from Oculus.
