Facebook’s virtual-reality subsidiary and two of its founders are facing a sobering reality after a jury hit them with a $500 million bill for violating the intellectual property rights of video-game maker ZeniMax Media. The verdict reached Wednesday in a Dallas federal court represents about one-fourth of the $2 billion that Facebook paid two years ago to buy Oculus, a developer of virtual-reality gear and software.
