Archer Secures Lilium eVTOL Patents Over Joby

Archer Secures Lilium eVTOL Patents, Outpacing Joby Aviation
Archer Aviation has significantly bolstered its standing in the electric vertical takeoff and landing (eVTOL) industry by acquiring approximately 300 patents from the German developer Lilium for nearly $21 million. The California-based company announced the acquisition on Wednesday, having prevailed over rival Joby Aviation in a competitive bidding process. This strategic move grants Archer access to a substantial portfolio of advanced air mobility (AAM) technologies, including high-voltage systems, battery management, and innovative aircraft design. These assets are expected to intensify competition with Joby as both companies seek to dominate the emerging eVTOL market.
Lilium’s Legacy and Archer’s Expansion
Lilium, once recognized for its seven-passenger eVTOL jet featuring 30 ducted electric fans embedded in its wings, ceased operations in February after failing to secure essential funding. In contrast, Archer has raised over $1.3 billion in the past year and is rapidly expanding beyond its initial focus on passenger air taxi services. The company intends to leverage the newly acquired intellectual property to enter cargo and defense sectors, building on its strategic partnership with Anduril Industries for military applications.
The patents obtained from Lilium encompass a broad range of technologies, including ducted fan propulsion, electric propeller and engine systems, battery management, and flight controls. Archer highlighted that Lilium invested more than $1.5 billion in developing these innovations. The ducted fan technology, in particular, is seen as a potential catalyst for new developments in both light sport and regional air mobility sectors, with the capacity to influence future aircraft designs.
Market Developments and Industry Dynamics
Archer is currently conducting crewed flight testing of its Midnight air taxi and is developing an autonomous, hybrid-electric model aimed at civil and military logistics. The company’s aggressive market entry was underscored by recent public demonstration flights at the California International Air Show, signaling its readiness to compete on a global scale.
Joby Aviation responded with its own public flight demonstration at the same event and announced plans to launch passenger flights in Dubai next year. However, it remains uncertain whether Joby will require Federal Aviation Administration (FAA) certification for these international operations. The rivalry between Archer and Joby is expected to intensify as both companies vie for leadership in the nascent eVTOL market, where potential revenue streams include military contracts and ride-sharing services.
Industry consolidation is accelerating amid revised timelines for commercial eVTOL service launches. While some developers initially promised passenger flights as early as 2024, consulting firm SMG now projects that Archer, Joby, and Beta Technologies will not commence commercial operations until at least 2027. The sector has witnessed several high-profile exits: Lilium’s former battery plant was recently acquired by Germany’s Vaeridion, which plans to develop a nine-passenger electric aircraft, and Dutch firm Advanced Air Mobility Group is negotiating to purchase Lilium’s test facilities near Munich. Other notable departures include Volocopter, which sold its assets to the Chinese parent company of Diamond Aircraft, and U.S.-based Overair, which has also encountered significant challenges.
As Archer integrates Lilium’s pioneering technologies, the company appears well-positioned to influence the next phase of eVTOL innovation and competition. CEO Adam Goldstein remarked, “Lilium’s pioneering work advanced the frontier of eVTOL design and technology, and we’re excited to bring their cutting-edge technologies into the fold at Archer as we advance our product roadmap.”
