Aviation Archer Acquires Patent Portfolio from Lilium's Insolvency Estate

2025-11-13 From Stefanie Eckardt | Translated by AI 1 min Reading Time

In August, it was reported that AAMG intended to invest in Lilium and thus save the German start-up from bankruptcy. But now the American company Archer Aviation has announced that it has won the bidding war for the acquisition of Lilium's portfolio with around 300 patents.

For a long time, it seemed that Lilium could be saved from insolvency through investments by AAMG. Now, Archer is taking over the approximately 300 patents of the German company.(Image: Lilium) — For a long time, it seemed that Lilium could be saved from insolvency through investments by AAMG.

Archer has offered 18 million euros (approx. 21 million USD) for the Lilium portfolio and has been awarded the contract. Lilium was founded in 2015 and has invested over 1.5 billion US dollars in the development of eVTOLs. Now Archer can claim approximately 300 patents for itself, covering innovations such as ducted fans, propeller systems, high-voltage systems, battery management, aircraft design, flight control, and electric motors.

Light aircraft in focus

With the acquisition, the company can cover current and future eVTOL technologies. Its portfolio now includes more than 1,000 patent assets worldwide. In particular, the ducted fan technology developed by Lilium is considered one of the most important innovations. This technology is ideally suited to advancing not only regional air mobility but also the field of light aircraft. This is a significant factor, especially in light of the announcement by the U.S. Department of Transportation and the Federal Aviation Administration in July of this year to modernize the final rule on the Special Airworthiness Certification (MOSAIC) to boost the light aircraft sector.
