Archer Aviation a pioneer in eVTOL aircraft, has won the bid to acquire Lilium GmbH’s advanced air mobility patent portfolio. The €18 million (US$20.7 million) agreement covers around 300 patents, including innovations in high-voltage systems, battery management, aircraft design, flight control, electric propulsion, and ducted fan technology.
This move cements Archer’s leadership in next-generation electric aviation. It also reinforces the company’s goal to ensure the United States remains at the forefront of eVTOL technology. The acquisition follows a wave of consolidation in the sector, such as the recent purchase of Volocopter by a Chinese buyer.
Adam Goldstein, Founder and CEO of Archer, said, “Lilium’s pioneering work advanced the frontier of eVTOL design and technology, and we’re thrilled to integrate their achievements into Archer’s roadmap.” Lilium reportedly invested over US$1.5 billion in developing key technologies for its visionary eVTOL platform, which many viewed as ahead of its time.
Through this strategic purchase, Archer gains access to critical intellectual property, including what is believed to be the world’s leading ducted fan patent collection. This technology could significantly enhance Archer’s current and future aircraft models.
In July 2025, the U.S. Department of Transportation and Federal Aviation Administration (FAA) introduced the MOSAIC final rule to modernise airworthiness certification for light-sport aircraft. Archer believes that Lilium’s ducted fan system could play a vital role in future developments across both the light-sport and regional air mobility markets.
By merging innovation and strategy, Archer continues to push electric aviation towards commercial reality, shaping the next era of cleaner, smarter flight.
