Wisk submits injunction to US federal judge to stop Archer from using confidential trade secrets
Wisk has filed a motion for a preliminary injunction to stop eVTOL aircraft developer Archer from using its confidential trade secrets ahead of a trial.
The company began legal action against Archer last month, and alleges its business is ‘built on intellectual property that is not its own’ and brings claims for trade secret misappropriation and patent infringement.
According to the filing sent to the federal court in the Northern District of California in April, the lawsuit follows Wisk’s discovery of suspicious file downloads by former employees who left the company to work for Archer, including thousands of files related to Wisk’s confidential aircraft, component and systems designs, manufacturing and test data.
Additionally, Wisk has said Archer’s recent disclosure of an aircraft design appears to be a copy of a design it developed and submitted in a confidential patent application to the U.S. Patent and Trademark Office in January 2020.

The copied design includes six front rotors that each consist of five blades and can tilt to be positioned either horizontally or vertically, as well as six rear rotors that each consist of two blades and remain fixed in a vertical position. The design also includes an unconventional ‘V’ tail.
A spokesperson for Wisk said: “The theft of our highly confidential files, the virtual copy of Wisk’s design from a confidential patent application, and Archer’s startlingly short operational history make clear that Archer’s program is built on Wisk’s intellectual property, as we outlined in our Complaint.
“With our motion for a preliminary injunction, we are asking the Court to stop Archer from using the valuable trade secrets stolen from Wisk. These trade secrets span the gamut of systems within the aircraft and processes for development. We look forward to presenting our case to the Court.
“We will continue to cooperate with the FBI and U.S. Department of Justice on their criminal investigation into Archer relating to the theft and use of Wisk’s intellectual property.”
At the time, Archer said it would defend itself ‘vigorously’ and in an updated statement, a spokesperson for the company said: “This a baseless motion in a baseless lawsuit. Archer independently designed its aircraft, before any employees from Wisk joined Archer, and Archer looks forward to demonstrating that in court.
“Archer is moving forward with its business plans, including the development, certification and production of its proprietary aircraft.”
