Guangzhi Cao, a former Tesla employee who worked on Autopilot, the electric-car maker’s semi-autonomous driver-assistance system, admitted in a July 8 court filing to uploading files related to Autopilot to his personal iCloud account before leaving to work at a competitor.
Tesla sued Cao in March, alleging that he had uploaded over 300,000 files and directories related to Autopilot to his iCloud account and created .zip files containing Autopilot’s source code. The company said in its lawsuit that Cao could be using the files at the electric-vehicle startup Xpeng Motors, also known as XMotors, where he’s currently employed. Xpeng Motors has developed driver-assistance features that are similar to Autopilot, Tesla said.

In the July 8 filing, Cao admitted to uploading Autopilot-related files to his iCloud account and making .zip files containing Autopilot source code, but he did not specify the size of those files. He denied that he is using the files to develop autonomous-driving technology at Xpeng Motors. Cao’s attorneys said in the filing that he “made extensive efforts to delete and/or remove any such Tesla files prior to his separation from Tesla,” and Cao denied that his actions damaged Tesla or created the potential for future harm.
Cao admitted in the filing that he did not tell Tesla about the Autopilot information he had copied before he left the company, but said the company never asked him about it.
“XMotors fully respects any third-party’s intellectual property rights and confidential information. The company has been complying and will comply all applicable laws and regulations,” an Xpeng Motors representative told Business Insider. “XMotors has by no means caused or attempted to cause Mr. Cao to misappropriate trade secrets, confidential and proprietary information of Tesla, whether such allegations by Tesla being true or not. XMotors was not aware of any alleged misconduct by Mr. Cao.”
Tesla did not immediately respond to Business Insider’s request for comment.
Tesla has also sued former employees who left to join the autonomous-driving startup Zoox, saying they stole proprietary information and trade secrets that helped Zoox accelerate the development of its warehousing, logistics, and inventory-control operations. At the time, Zoox and the employees named in the lawsuit did not respond to Business Insider’s requests for comment. Zoox did not immediately respond to a request for comment on Thursday.
Concerns about employees bringing proprietary technology to competitors extends beyond Tesla in the autonomous-driving industry. The Google spin-off Waymo alleged in a 2017 lawsuit that former engineer Anthony Levandowski stole trade secrets from the company that were later used by Uber’s autonomous-driving division. The suit was settled in 2018, with Uber agreeing to give Waymo $245 million in equity, though Uber CEO Dara Khosrowshahi said in a blog post that he did not believe Uber had used or received any proprietary information from Waymo.
