We found that six weeks before his resignation this former 
  employee, Anthony Levandowski, downloaded over 14,000 
  highly confidential and proprietary design files for 
  Waymo’s various hardware systems, including designs of 
  Waymo’s LiDAR and circuit board. To gain access to Waymo’s 
  design server, Mr. Levandowski searched for and installed 
  specialized software onto his company-issued laptop. Once 
  inside, he downloaded 9.7 GB of Waymo’s highly 
  confidential files and trade secrets, including 
  blueprints, design files and testing documentation. Then 
  he connected an external drive to the laptop. Mr. 
  Levandowski then wiped and reformatted the laptop in an 
  attempt to erase forensic fingerprints.
