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. We are disappointed but not surprised by Zenimax's actions and we will prove that all of its claims are false.
A key reason that John permanently left Zenimax in August of 2013 was that Zenimax prevented John from working on VR, and stopped investing in VR games across the company.
There is not a line of Zenimax code or any of its technology in any Oculus products. Zenimax did not pursue claims against Oculus for IP or technology, Zenimax has never contributed any IP or technology to Oculus, and only after the Facebook deal was announced has Zenimax now made these claims through its lawyers.
Zenimax canceled VR support for Doom 3 BFG when Oculus refused Zenimax's demands for a non-dilutable equity stake in Oculus. Zenimax has never identified any 'stolen' code or technology [in Oculus's open source].
