SAN FRANCISCO — A federal judge on Tuesday granted Waymo's request to delay a jury trial over whether Uber is using pilfered Waymo trade secrets in its own autonomous driving program. U.S. District Judge William Alsup of the Northern District of California said he would push back the trial to Dec. 4, about two months after the original start date of Oct. 10. Alsup said the trial will run until Dec. 20, and could spill into January. Waymo made the request for more time after obtaining a due diligence report that digital forensics firm Stroz Friedberg conducted before Uber acquired Ottomotto, a company started by former Waymo employees. That report—the main summary of which was filed publicly Monday night—focused on whether those employees possessed any files from Google, Waymo's parent company. One of the employees is Anthony Levandowski, a former top engineer at Waymo who later led Uber's driverless car program. Waymo's attorneys at Quinn Emanuel Urquhart & Sullivan say they learned from the report for the first time that Levandowski had taken thousands of software source code files that may contain Waymo trade secrets. Alsup said he would still limit the number of trade secrets that Waymo may assert to nine, but could pick different secrets depending on what it finds in assessing the newly obtained files. The judge also expressed skepticism that Waymo will turn up information that will significantly strengthen its case. “[Waymo] has a case to be made there but it is not the home-run that they were expecting to find,” he said. “It seems unlikely to me that you're going to find much more.” In an emailed statement, an Uber spokeswoman said that the company was ready for trial now, and would remain ready “after this very brief continuance.” “The court has made clear that Waymo's case is not what they hoped, and that more time will not change the hard fact that their trade secrets never came to Uber,” she wrote.
