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 Robotaxi is set to launch in the coming days, but the first rides will be confined to those who receive invitations that the company sends out. However, CEO Elon Musk revealed the date that Tesla is aiming for when anyone in the general public will be able to call for a Robotaxi.

There has been quite a bit of information today about what appears to be an imminent launch of the Robotaxi platform. The first video of a Robotaxi was captured on a public road in Austin today, just one day after Tesla was added to the City of Austin’s list of licensed autonomous vehicle operators.

In the coming days, it is expected that Tesla will launch the Robotaxi platform in Austin to a select few. For now, Tesla is taking this ultra-conservative approach as it pertains to the rollout, citing safety precautions. It will be the first time Tesla has done this in public and offered it to people outside of the company.

It did launch a small, limited version of it to employees last month in Austin and the San Francisco Bay Area, but there was someone in the driver’s seat. Today’s video only had an occupant in the passenger seat.

People are eager to know: when will they be able to fetch a driverless Tesla Model Y Robotaxi in Austin for themselves? Musk finally answered the long-awaited question with a tentative date of June 22:

Safety remains the ultimate priority for Tesla with this cautious rollout https://t.co/Mw5kOzA9Sm

Musk cited that Tesla’s utmost priority is still safety and not necessarily the speed of rollout. The current plan seems to be to deploy it in a controlled and slow fashion until confidence is at an extremely high level. Musk seems to believe the rollout will go smoothly, as the date comes less than two weeks after the initial launch.

Anyone who has experienced Full Self-Driving for themselves knows what the cars are capable of. However, Tesla, at this point in time, still requires drivers to pay attention and remain ready to take over the wheel in case of an emergency. This will be a major step in the right direction for Tesla as it prepares to launch Robotaxi in Austin and slowly expand to surrounding areas.

Tesla CEO Elon Musk says the automaker’s Robotaxi platform launch later this month will essentially force other companies to license Full Self-Driving to achieve their own goals of achieving autonomy.

Musk’s statement comes as a video captured today showed the first Tesla Robotaxi test mules on public streets in Austin, Texas, just one day after the City officially listed the company as an autonomous vehicle operator.

A prediction by investing YouTube and Tesla community member Dave Lee stated that “at least one automaker by end of year” will license Full Self-Driving from the Musk-led company, as it will give rivals the confidence to use the software to run their own self-driving operations.

Lee detailed his theory by stating that the company that chooses to commit to FSD licensing will not be able to integrate the hardware and sell those units immediately. Instead, it will take two years or so to solve the engineering and design applications.

Musk revealed his true thoughts on other automakers’ attempts at vehicle autonomy, and said many are being told that Robotaxi is not real or that they can solve their problems with hardware orders to Nvidia.

He went on to say that companies will be forced to turn to Tesla at some point or another, because Robotaxi will be widespread and their solutions to figuring out an effective deployment will prove to be failures:

“The automakers keep being told that this isn’t real or that just buying some hardware from Nvidia will solve it. As Tesla robotaxis become widespread and their other solutions don’t work, they will naturally turn to us.”

Musk has not been shy to respond to speculation regarding the video of the Robotaxi, which was shared on X earlier today. This is perhaps one of the more fiery things he revealed. He seems ultra-confident in what Tesla will prove and achieve in the near future with the launch of the Robotaxi platform.

Many believe it will be rolled out this month. Bloomberg reported recently that Tesla was internally aiming for June 12. The company has not directly responded to these rumors.

Tesla has discussed on several occasions that it is in talks with an automaker about licensing Full Self-Driving, but it has never revealed who. The company first revealed discussions with another automaker in early 2024 when Elon Musk said:

“We’re in conversations with one major automaker regarding licensing FSD. It really just becomes a case of having them use the same cameras and inference computer and licensing our software. Once it becomes obvious that if you don’t have this (FSD) in a car, nobody wants your car. It’s a smart car… The people don’t understand all cars will need to be smart cars, or you will not sell, or nobody would buy it. Once that becomes obvious, I think licensing becomes not optional.”

Many, including us, suspected that Ford was the company that Tesla was speaking of due to Musk’s relationship with Jim Farley, which resulted in the legacy automaker being the first major car company to adopt Tesla’s North American Charging Standard (NACS), which gave them access to the Supercharging Network.

This catalyzed an onslaught of companies choosing to make the same move as Tesla had truly set itself apart in terms of charging infrastructure.

Companies may be forced to make a similar decision if it can make the same type of statement with the rollout of Robotaxi.
