Archer Aviation Inc. (NYSE: ACHR) has successfully secured the acquisition of Lilium GmbH's portfolio of approximately 300 advanced air mobility patent assets for €18 million. This purchase significantly bolsters Archer's patent portfolio, which now encompasses over 1,000 patent assets worldwide. The acquisition includes patents covering key innovations in high-voltage systems, battery management, advanced aircraft design, flight controls, electric engines, propellers, and ducted fans.

Lilium, which was founded in 2015 and invested over $1.5 billion in developing advanced technologies related to electric vertical takeoff and landing (eVTOL) aircraft, has made a substantial contribution to the field. Through this acquisition, Archer is poised to integrate Lilium's cutting-edge technologies into its own product roadmap.

This move comes in the wake of industry consolidation in the advanced air mobility sector, including the recent acquisition of Volocopter by a Chinese buyer. Adam Goldstein, founder and CEO of Archer, expressed excitement about incorporating Lilium's groundbreaking technologies and emphasized the significance of advancing their product roadmap.

Archer's strategic vision is further underpinned by the belief that Lilium's ducted fan technology could unlock future development opportunities across the light-sport and regional air mobility sectors. This sentiment is reinforced by the U.S. Department of Transportation and Federal Aviation Administration's announcement in July 2025 regarding the modernization of the Special Airworthiness Certification (MOSAIC) final rule, aimed at driving innovation in the light-sport sector.

Archer's commitment to ensuring the U.S. leads the way in critical eVTOL technology is evident through this acquisition, which strengthens its position in next-generation electric aviation. The company's dedication to designing and developing key enabling technologies and aircraft to power the future of aviation is further underscored by this strategic move. The market has reacted to these announcements by moving the company's shares -8.9% to a price of $11.87. If you want to know more, read the company's complete 8-K report here.
