Archer, which unveiled its Maker eVTOL earlier this month, alleged in a court filing late Wednesday that Wisk learned of Archer’s aircraft design weeks before it filed its patent design application – effectively reversing claims that it stole Wisk’s design. > Wisk claimed in its April lawsuit that its design is nearly identical to Archer’s, and that the similarities are the result of a former Wisk employee (who was later hired by Archer) stealing proprietary work files. In this new filing, Archer alleged that it shared its plans for a 12-rotor tilting design with Geoff Long, a senior engineer at Wisk, whom Archer was considering recruiting. Archer alleges that Long shared Archer’s plans with Wisk executives weeks before Wisk filed its patent application.
