Archer has acquired the full patent portfolio of defunct German eVTOL startup Lilium for €18 million ($21 million), adding around 300 assets spanning high-voltage systems, advanced aircraft design, flight controls, ducted fans, and electric propulsion. The acquisition strengthens Archer’s intellectual property position as consolidation accelerates in the advanced air mobility sector.

Founded in 2015, Lilium was once a high-profile electric aircraft company backed by Tencent and Saudi investors, raising over $1 billion before entering insolvency.

Archer’s bid surpassed those from Joby Aviation and Ambitious Air Mobility Group.

The company now holds more than 1,000 global patent assets, a base it plans to leverage across both its commercial air taxi and emerging defense programs.

While Archer has not disclosed specific plans for integrating the new technologies, the Lilium patents, particularly around ducted fan systems, could open opportunities beyond short-haul urban transport and into regional electric flight.
