Tesla takes legal action against ex-engineer, accused of stealing confidential information about Optimus
In a significant turn of events, Tesla Inc. has filed a lawsuit against Proception Inc., a Palo Alto-based startup founded by two former Tesla engineers, Zhongjie "Jay" Li and Yang You, over allegations of trade secret theft. The lawsuit, filed on July 12, 2025, accuses Proception of developing humanoid robotic hands that bear a striking resemblance to those built under Tesla's Optimus program [1].
At the heart of the lawsuit is the claim that Li, who worked at Tesla from 2022 to 2024 as an engineer on the humanoid robot program, misappropriated trade secrets before leaving to launch Proception Inc. [1] [2] [3]. Tesla argues that within five months of his departure, Proception claimed to have developed humanoid robotic hands, and this timeline, they assert, would not have been possible without leveraging misappropriated intellectual property [1].
The lawsuit cites violations under the Defend Trade Secrets Act and California's Uniform Trade Secrets Act [4]. Tesla is seeking compensatory and exemplary damages, as well as a court order barring Li and Proception from using any of Tesla's proprietary materials [5].
The case, titled Tesla Inc. v. Proception Inc. et al., Case No. 5:25-cv-04963, is currently underway in the U.S. District Court for the Northern District of California [6]. As of now, Li and his company have not responded publicly to the lawsuit [7].
The lawsuit also includes claims of unjust enrichment and improperly disrupting Tesla's existing or potential business relationships [8]. It is important to note that this case is not related to the use of referral links for purchasing Tesla vehicles [9].
The full complaint can be found below for those interested in further details [10]. It is worth mentioning that, as of July 18, 2025, no direct details or allegations against Zhongjie Li have been surfaced or reported in the accessible information [11].
In the final weeks of his employment, Li is said to have downloaded confidential files related to robotic hand development onto two personal smartphones [2]. Li accessed internal systems just hours before his departure from Tesla [3]. However, there is no explicit mention or detailed information concerning Zhongjie Li's involvement or allegations in this lawsuit beyond these points [11].
As the case progresses, more information may become available, shedding light on the specifics of Zhongjie Li's role and actions related to the alleged trade secret theft. Until then, the public is left to follow the developments in this high-stakes legal battle between Tesla and Proception Inc.

Technology plays a crucial role in this legal dispute, with Tesla accusing Proception Inc. of developing humanoid robotic hands by leveraging misappropriated intellectual property from Tesla's Optimus program. Artificial Intelligence might also come into play, as the timeline suggested by Proception for the development of their robotic hands is under scrutiny, raising questions about the efficiency of their AI-driven design process.
