Oculus VR has responded to claims by ZeniMax Media that the Oculus Rift headset relied on ZeniMax’s technology. Oculus said they are “We are disappointed but not surprised by ZeniMax’s actions and we will prove that all of its claims are false.” Late last week the Wall Street Journal reported a claim that the Rift incorporated technology brought over from a former ZeniMax employee, in violation of a non-disclosure agreement. ZeniMax had sent letters detailing their complaint to both Oculus VR and Facebook, which is in the process of acquiring Oculus for $2 billion.
