Back in 2014, ZeniMax Media sued Oculus in a lawsuit claiming the company stole important, foundational elements for what we now know as the Oculus Rift. Since 2014, an ongoing lawsuit against the now Facebook-owned company has been running, racking up an impressive $2 billion in fees, as the companies continue to feud over who actually owns the technology for the virtual reality headset. At the beginning of the lawsuit, ZeniMax provided a copy of the legal filing of the case to Polygon, showing their side of the case and expressing that Oculus had “wrongfully taken … ZeniMax[‘s] intellectual property and commercially exploited it for their own gain.” This issue came up when the company accused former employee, John Carmack, of sharing important technological information with Oculus founder, Palmer Luckey.

Now, with the trial to decide who has wrongfully taken intellectual property and who is innocent well under way, ZeniMax has reached out to Polygon again, expressing their intentions to further prove that they are the true owners of the Oculus Rift technology.

With the start of the trial of our case in Federal District Court in Dallas against Defendants Facebook, Oculus and its management, ZeniMax and id Software welcome the opportunity to present substantial evidence of the Defendants’ misappropriation of our Virtual Reality (VR) intellectual property. That evidence includes the theft of trade secrets and highly confidential information, including computer code. ZeniMax will also present evidence of the Defendants’ intentional destruction of evidence to cover up their wrongdoing. ZeniMax and id Software are the visionary developers of breakthrough VR technology, and look forward to the vindication of our claims.

Of course, both Facebook and Oculus have denied this, as Mark Zuckerberg himself has testified against the allegations that Oculus had anything to do with stealing such intellectual property. “We are highly confident that Oculus products are built on Oculus technology,” Zuckerberg said in his testimony. “The idea that Oculus products are based on someone else’s technology is just wrong.” Zuckerberg also added in his testimony, “It is pretty common when you announce a big deal or do something that all kinds of people just kind of come out of the woodwork and claim that they just own some portion of the deal. Like most people in the court, I’ve never even heard of ZeniMax before.”

This isn’t the only time Oculus has come under legal fire. Just last month, Dov Katz, the executive Head of Computer Vision for Oculus, was arrested in an underage sex sting and arrested just before Christmas, further adding to the list of scandals that have overtaken the Virtual Reality company within the past half-decade.

As of right now, the trial between ZeniMax, Oculus and Facebook is still ongoing. so make sure you check back frequently as the story unfolds to keep yourself in the know as we bring you updates on the case.
