In the latest bad news for Uber, the judge presiding over its trade secrets lawsuit with Google self-driving car unit Waymo has asked federal prosecutors to investigate the case. Reuters and Bloomberg report that US District Judge William Alsup said he is not taking a position on whether or not charges are warranted, but this is the second investigation into Uber, along with an inquiry into its "greyballing" scheme. At the same time, he denied a request by Uber to take the case to private arbitration, opting to keep things in the public eye, and also partially granted Waymo's request for an injunction.
