Tesla filed a lawsuit this week against four former employees for allegedly stealing trade secrets and providing them to a rival company. According to the complaint filed with the US district court for Northern California, the ex-Tesla workers gave confidential information to autonomous vehicle start-up Zoox. The documents allegedly allowed the company to accelerate the development of its technology by cribbing off of Tesla's proprietary work. According to Tesla, the four former employees violated the terms of their contracts by forwarding documents and other information from work email addresses to personal accounts. The files included inventory documents, company schematics and other proprietary pieces of information.

Zoox, a once-secretive self-driving car startup, is closing a $500 million raise at a $3.2 billion post-money valuation, Bloomberg Businessweek reports. Prior to the deal, Zoox was valued at $2.7 billion, Zoox confirmed to TechCrunch. The round, led by Mike Cannon-Brookes of Grok Ventures, brings its total amount of funding to $800 million. Zoox's plan, according to Bloomberg, is to publicly deploy autonomous vehicles by 2020 in the form of its own ride-hailing service. The cars themselves will be all-electric and fully autonomous.
