Archer Aviation Inc. announced today, 17 October 2025, that it has won a competitive bid to acquire the entire patent portfolio of Lilium GmbH, a leading electric‑vertical‑takeoff‑and‑landing developer. The deal covers roughly 300 advanced air‑mobility patents and is valued at €18 million, or about $21 million.
The portfolio includes intellectual property related to high‑voltage systems, battery management, flight controls, electric engines, propellers, and ducted‑fan technology. By adding these assets, Archer expands its technology base and strengthens its leadership position in next‑generation electric aviation.
Strategically, the acquisition consolidates key technologies that can accelerate Archer’s Midnight eVTOL development and support future product variants. The move also positions Archer to better defend against competitors and to leverage Lilium’s innovations in future commercial and defense programs.
