Tesla Sues Former Optimus Engineer Over Alleged Trade Secret Theft
Allegations of trade secret theft are shaking Tesla’s robotics division as the company takes legal action against a former engineer who helped develop its Optimus humanoid robots. Tesla is suing a former employee for allegedly stealing confidential data tied to its cutting-edge robotic hand technology and using that knowledge to launch a competing startup, Proception, which now claims to be building some of the world’s most advanced humanoid robotic hands.
This lawsuit is making waves in the AI and robotics space and raises critical concerns about intellectual property protection, corporate loyalty, and how emerging tech startups are born—sometimes from within competitors. So what exactly happened, and why is Tesla's Optimus program now at the center of a high-stakes legal showdown? Let's break it all down.
Tesla Sues Former Engineer for Stealing Trade Secrets from Optimus Program
According to court filings first reported by Bloomberg, Tesla filed a lawsuit on June 12, 2025, against Zhongjie “Jay” Li, an ex-Tesla engineer who worked on its humanoid robot program from August 2022 to September 2024. Tesla alleges that Li downloaded proprietary designs and technical documentation related to robotic hand sensors—key components of Tesla’s Optimus robot project—onto two of his personal smartphones before leaving the company.
The lawsuit claims that Li actively researched topics like “humanoid robotic hands”, startup funding, and venture capital opportunities during his final months at Tesla. Within a week of his departure, he founded Proception, a Y Combinator-backed robotics startup that went public just five months later, claiming it had already “successfully built advanced humanoid robotic hands.”
Tesla's legal complaint highlights that the robotic hands unveiled by Proception “bear a striking resemblance” to the designs Li worked on while employed at Tesla. According to Tesla, this is clear evidence that the startup's product is a direct result of stolen intellectual property.
What Is Tesla's Optimus Robot and Why It Matters
The Tesla Optimus program—also known as Tesla Bot—was first announced by Elon Musk in 2021 as a futuristic humanoid robot designed to automate mundane tasks and assist humans in day-to-day life. Tesla initially promised a prototype in 2022 and announced plans to make the robot commercially available by 2026.
While progress has been slow, with many demonstrations involving human-controlled bots rather than fully autonomous machines, Tesla has made it clear that Optimus represents a long-term strategic bet on AI-driven robotics. During its October 2024 “We, Robot” event, Optimus bots were showcased, but most actions were revealed to be remotely controlled rather than AI-powered.
By targeting robotic hand dexterity—one of the most technically challenging aspects of humanoid design—Tesla aimed to differentiate itself from other robotics firms. If Li did in fact take sensitive data from this program, it could potentially offer Proception a huge competitive edge in a field where even slight design advantages translate to years of R&D gains.
Proception: The Startup at the Center of the Controversy
Proception, the startup allegedly founded using Tesla’s stolen tech, is a new entrant in the humanoid robotics space that promises to “revolutionize human-robot interaction.” Backed by Y Combinator, Proception has quickly gained visibility by showcasing robotic hands that demonstrate high degrees of flexibility, movement, and articulation—functions that Tesla claims were derived from its own blueprints.
While Proception has not yet issued a formal response to Tesla’s lawsuit, its website continues to promote its mission and features visual demonstrations of robotic hand technologies that Tesla says are too similar to its own to be coincidental. The legal battle now centers on whether Li’s work at Tesla and his quick move to launch a similar product breach trade secret laws and employment confidentiality agreements.
If proven true, the case could set a new precedent for how closely IP protections are enforced in the robotics and AI industries, particularly where employees leave high-tech roles to start their own ventures.
Legal and Industry Implications of the Tesla Lawsuit
Tesla’s lawsuit isn’t just about one former employee—it’s a signal to others in the tech industry. The case underscores how aggressively companies will move to protect their AI and robotics IP, especially in an era where talent is mobile, and startup funding is abundant.
This also sparks conversation around how companies should handle trade secrets, NDAs (non-disclosure agreements), and employee offboarding processes when working on projects as sensitive as humanoid robotics. For Tesla, the Optimus project isn’t just a product—it’s a symbol of its vision for a post-AI world, and the theft of any part of that could result in years of lost R&D, competitive advantage, and brand trust.
If the courts rule in Tesla’s favor, it may not only result in damages awarded or injunctions placed on Proception, but it could also dissuade future engineers from walking away with intellectual property from their employers. For Proception, the legal outcome could mean delays, a loss of investor trust, or even a full halt to its operations if its tech is deemed derivative.
A Cautionary Tale in the Age of AI and Robotics
As Tesla sues a former engineer over alleged theft of trade secrets from its Optimus humanoid robot program, the lawsuit serves as a cautionary tale for startups, engineers, and large corporations alike. The intersection of AI innovation, intellectual property, and employee mobility is growing increasingly complex, especially as competition heats up in the race to develop functional, market-ready humanoid robots.
Whether Tesla wins or loses this lawsuit, one thing is clear: the road to robotic innovation is fraught with legal landmines, and safeguarding technology is now just as important as building it.
