Tesla is suing former Optimus engineer Jay Li in federal court after accusing him of stealing trade secrets and using them to enable a startup he founded after he left.
Li is accused of stealing confidential files and using them to help get his company, “Proception,” off to a rocking start. Tesla says the files Li took helped his new startup “shortcut the typical development process” for robot hands, something that took Tesla years to develop and evolve.
The company said in the complaint (via Reuters):
“Through Li’s pilfering, Defendant Proception purportedly achieved in a matter of months what it has taken Tesla over four years, hundreds of employees, and billions of dollars to achieve.”
Li was an employee at Tesla for several years, working on the Optimus sensor team from 2022 to 2024. The company says it utilized and devoted “extraordinary resources” to the development of Optimus, which has come a long way since its unveiling several years ago.

Li allegedly downloaded confidential files related to Optimus’ robotic hand movement research before departing the company. He did not work on the hands at the time. However, he left and swiftly started Proception, as the suit states the company was founded just six days after he left Tesla.
Proception was gloating about its ability to build robotic hands just five months after the company was founded. Tesla says the hands have “striking similarities” to its own design for Optimus.
The company is looking for monetary damages and a court order that would block Proception from misusing the secrets it accuses Li of taking.
This is not the first suit Tesla has filed over trade secrets and confidential information theft. Recently, it accused German-Canadian dual citizen Klaus Pflugbeil of stealing battery-related secrets. He was arrested and sentenced to two years in prison.

Tesla is being represented by Josh Krevitt, Orin Snyder, and Angelique Kaounis of Gibson Dunn & Crutcher.
The case is Tesla Inc. v. Perception Inc., U.S. District Court for the Northern District of California, No. 5:25-cv-04963.
