Archer sues Vertical over alleged copying of its eVTOL design and tech, citing patent infringement.
Archer Aviation has sued Vertical Aerospace, alleging its Valo eVTOL aircraft copies design and technical features of Archer’s Midnight model, including its V-tail, fuselage, and flight control systems, violating two design patents and one utility patent.
The lawsuit, filed in Texas on February 23, 2026, claims Vertical’s aircraft is a visual mimic and infringes on key propulsion and power management technology.
Vertical denied the allegations, calling them a distraction, and emphasized its own proprietary innovations.
The case coincides with growing competition and financial pressures in the eVTOL sector, with Archer citing strong cash reserves and Vertical warning of potential funding shortfalls by mid-2026.
