Archer hits back and alleges Wisk copied its eVTOL design in latest update to ongoing lawsuit
In the latest update surrounding its ongoing lawsuit with Wisk Aero, Archer Aviation has claimed Wisk filed its aircraft design patent application just weeks after learning of Archer’s own design.
A filing submission submitted last week by Archer says Wisk’s chief Engineer learned of its aircraft design during a recruiting meeting in December 2019 and shared the information with senior executives at Wisk. Weeks later, the company filed a patent application for an aircraft design which appeared similar to the one described to him by executives at Archer.
Attorneys from Archer made the accusation in opposition to Wisk’s request for a preliminary injunction, which intends to stop Archer from using its confidential trade secrets ahead of a trial. The opposition added that Wisk’s requested injunction is ‘so ill-defined and overbroad that it effectively would shut down Archer’s aircraft development, with potentially catastrophic effects…’
Archer announced a joint SPAC merger with Atlas Investment Corp. earlier this year and if the preliminary injunction was granted, it would threaten the business deal with Archer set to potentially lose $1.1 billion in gross proceeds.
It stems from a recruiting meeting that Archer co-founders Brett Adcock and Adam Goldstein had with Wisk’s senior engineer Geoff Long.
Adcock and Goldstein told Long about their plans for the company’s eVTOL aircraft, which included working with Flighthouse on a fixed-wing aircraft with a 12-rotor tilting design. They also told Long they were considering having two or six tilting rotors.
A few days later, Long spoke to Wisk CEO Gary Gysin and Chief Technology Officer Jim Tighe about Archer’s aircraft design and that it was working with a third-party consultant. Wisk then submitted its patent application on January 31st, 2020.
The preliminary injunction was submitted following Wisk’s discovery of suspicious file downloads by former employee Jing Xue, 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.
Archer says however that the day after the motion was filed, it carried out its own internal investigation to identify any Wisk confidential information on its systems, saying: “There were zero hits among the 851 documents Wisk claims Xue downloaded and support Wisk’s trade secrets.”
Zero hits were also reported on ‘near duplicate files’ and Archer even requested the FBI provide an image of Xue’s laptop that had been seized to search for Wisk’s files. Xue has denied under oath that he has supplied documents of confidential information to any employer at Archer, and Archer has asked the court to deny Wisk’s request for a preliminary injunction.
A spokesperson for Wisk said: “Archer’s latest filing is full of inaccuracies and attempts to distract from the serious and broad scope of misappropriation claims it faces. The filing changes nothing. We look forward to continuing our case in court to demonstrate Archer’s improper use of Wisk’s intellectual property.”
