Overview

  • The deal transfers roughly 300 patents spanning ducted fans, propellers, high‑voltage systems, battery management, flight controls, electric engines and advanced aircraft design.
  • Archer said the acquisition lifts its intellectual property holdings to more than 1,000 patent assets, while its shares rose about 8.5% in morning trading, according to Reuters.
  • The Air Current reported the auction drew interest from rival Joby Aviation, highlighting the competitive value of the portfolio.
  • CEO Adam Goldstein described the move as strengthening Archer’s legal posture following the company’s past IP dispute with Boeing subsidiary Wisk.
  • Lilium invested over $1.5 billion before its 2024 insolvency, and Archer says the acquired ducted‑fan technology could enable future work in light‑sport and regional air mobility under MOSAIC.
