An anonymous reader quotes a report from Ars Technica: A U.S. federal judge has ordered Uber to bar its top self-driving car engineer from any work on LiDAR, and return stolen files to Google's self-driving car unit Waymo. Today's order by U.S. District Judge William Alsup demands Uber do "whatever it can to ensure that its employees return 14,000-plus pilfered files to their rightful owner." The files must be returned by May 31. The order was granted last week, but just made public in an unsealed document this morning. U.S. District Judge William Alsup found that Uber "likely knew or at least should have known" that the man it hired as its top self-driving car engineer, Anthony Levandowski, took and kept more than 14,000 Waymo files. Those files "likely contain at least some trade secrets," making some "provisional relief" for Waymo appropriate. Levandowski has previously asserted his Fifth Amendment rights with respect to his possession of the files. "If Uber were to threaten Levandowski with termination for noncompliance, that threat would be backed up by only Uber's power as a private employer, and Levandowski would remain free to forfeit his private employment to preserve his Fifth Amendment privilege," Alsup wrote. Several factors limit the amount of relief Waymo might receive. First of all, in the judge's view, not all of the 121 elements that Waymo defines as "trade secrets" are really trade secrets. Additionally, the judge has slapped aside Waymo's patent infringement accusations as "meritless."
