Update: Oculus has responded to today's lawsuit. A statement to Kotaku reads, "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."
Original story: Nearly three weeks after accusing Oculus VR and John Carmack of stealing their intellectual property, Zenimax and id Software have formally filed suit against the company in a Texas court.
The lawsuit claims that Oculus misappropriated trade secrets and accuses founder Palmer Luckey of breach of contract, copyright infringement, unfair competition, unjust enrichment, trademark infringement, and false designation.
"Intellectual property forms the foundation of our business," Zenimax Chairman & CEO Robert Altman said in a press release. "We cannot ignore the unlawful exploitation of intellectual property that we develop and own, nor will we allow misappropriation and infringement to go unaddressed."
Oculus has, to this point, denied Zenimax's claims, stating, "We are disappointed but not surprised by Zenimax's actions and we will prove that all of its claims are false. There is not a line of Zenimax code or any of its technology in any Oculus products."
