Ars Technica is reporting that Zenimax has had a partial victory in their court case against Oculus (and therefore Facebook)... Zenimax won't be crying too hard over the "partial" part, they're still taking home the grand prize of $500 Million. Why do we care? Well this case is probably the reason why Bethesda announced Fallout 4 VR for the HTC Vive, and not the Oculus.
At the heart of the case was the Oculus VR gaming headset itself. As Zenimax put it in their submissions, when Zenimax and Oculus started working together on the device, there was little more than a screen to the now famous VR device. With no head-tracking, no software, not even a strap to put the screen to your face, the oculus would have likely been just another piece of vaporware, as emails from famed inventor Palmer Luckey showed him admitting that he did not have the skills to get the device into a marketable state.
Zenimax obliged by performing much of the development, and ported some of their games to the device to allow it to be shown off.
Zenimax however forgot the first rule of business - always have a contract - Oculus and Zenimax never quite got around to detailing what help Zenimax would provide and on what terms.. Although they had a non disclosure agreement with Oculus to not show off Zenimax owned code or claim publicly that Zenimax endorsed the product... It seems the Jury agreed that Oculus did not keep to this agreement, but did not agree that any Zenimax "secrets" were stolen.
