Mark Zuckerberg suited up for court this week as he testified in a $2 billion Oculus lawsuit. The claim is that Oculus was built upon technology stolen from ZeniMax Media. The court analyzed the help that Oculus founder Palmer Luckey sought out from the employee of ZeniMax-owned games company id Software, John Carmack, when he was building his initial VR headset product. The Facebook CEO remained defiant of the claims, telling the court that “Oculus products are based on Oculus technology.” Throughout the case, a few new details about the Facebook/Oculus deal were revealed. Among them, Facebook agreed to pay $700 million in employee retention bonuses for key people.
