Actually, no, they didn't. Oculus claims this, but this seems to be untrue. What the jury found was that code in the Oculus software was definitely copied from Zenimax. However, they found that Zenimax failed to prove that this code constituted 'trade secrets' that were stolen from them. So, unless John Carmack, Palmer Luckey and/or some other Oculus developer or developers, by sheer coincidence, managed to create the exact same code, the code was stolen, it's just Zenimax failed to prove to the jury that this code legally qualified as 'trade secrets'.
