Wisk Aero, the air mobility company borne out of a joint venture between Kitty Hawk and Boeing, filed a lawsuit Tuesday against Archer Aviation alleging patent infringement and trade secret misappropriation.

Wisk claims in the lawsuit that Archer perpetrated a “brazen theft” of confidential information and intellectual property. The lawsuit points to the design of Archer’s first electric aircraft that was released in February, which Wisk says is a copy of one of its potential designs. That design was submitted to the U.S. Patent and Trademark Office in January 2020, and Wisk alleges the similarities are too numerous to have been a coincidence.
