By Ahmed Jameison • Sunday, October 19 10:17 • Permanent Link

Archer Aviation Inc. (NYSE: ACHR) has announced its successful acquisition of Lilium GmbH's portfolio of approximately 300 advanced air mobility patent assets for €18 million. This acquisition significantly bolsters Archer's existing patent portfolio, which now comprises over 1,000 patent assets worldwide.

Lilium, established in 2015, dedicated over $1.5 billion to developing advanced technologies in the electric vertical takeoff and landing (eVTOL) aircraft space. The acquired patent portfolio consists of crucial innovations in eVTOL technology, covering areas such as ducted fans, propeller systems, high-voltage systems, battery management, aircraft design, flight controls, and electric engines.

The transaction strengthens Archer's position in the next-generation electric aviation sector and underscores its commitment to ensuring the U.S. leads in pivotal eVTOL technology. The acquisition is particularly noteworthy given the recent consolidation in the advanced air mobility sector, exemplified by the acquisition of Volocopter by a Chinese buyer.

Adam Goldstein, Founder and CEO of Archer, expressed excitement about integrating Lilium's cutting-edge technologies into their product roadmap, citing Lilium's pioneering work in advancing the frontier of eVTOL design and technology.

Archer's strategic move comes on the heels of the U.S. Department of Transportation and Federal Aviation Administration's announcement in July 2025 of the modernization of the special airworthiness certification (MOSAIC) final rule, aimed at driving innovation across the light-sport sector. The acquisition of Lilium's ducted fan technology is anticipated to unlock future developments in both the light-sport and regional air mobility sectors.

With this acquisition, Archer has significantly expanded its technological capabilities and patent coverage, positioning itself at the forefront of eVTOL innovation and development.

Archer is a leading developer of eVTOL aircraft, dedicated to designing and developing the essential technologies and aircraft vital for shaping the future of aviation. Following these announcements, the company's shares moved -8.9%, and are now trading at a price of $11.87. Check out the company's full 8-K submission here.
