Facebook's Oculus VR charged with stealing patents, Zuckerberg denies it in court

Faebook CEO Mark Zuckerberg testified at a hearing in federal court in Dallas on Tuesday, denying game developer Zenimax's accusation that Facebook's Oculus unit stole its virtual reality technology.

ZeniMax filed a lawsuit against Oculus in 2014, when Facebook was in the process of acquiring the startup for $2 billion. Allegations at the time alleged that Oculus illegally obtained intellectual property from ZeniMax while developing virtual reality systems, including Rift headset.

ZeniMax alleged in the indictment that Oculus founder PalmerLuckey lacked relevant technical knowledge and did not develop a practical display for the Oculus Rift. The Oculus Rift was gradually formed with the help of Zenimax employees and others, who provided key software and hardware. Therefore, ZeniMax accused former Zenimax employees Kamak and others who had moved to Oculus of stealing the company's intellectual property rights. At the same time, ZeniMax also accused Facebook of knowing that the latter's technology had been stolen from ZeniMax when it acquired Oculus in 2014.

Zuckerberg told the jury in testimony on Tuesday that the allegations were false. "Oculus products are developed based on Oculus technology." he said.

Zuckerberg said that Facebook's acquisition of Oculus not only included a $2 billion purchase price, but also included a $700 million retention bonus and a $300 million so-called "milestone payment." Zuckerberg said Facebook's acquisition of Oculus was completed over the weekend of 2014.
