Astronics wins UK appeal ruling in Lufthansa Technik patent dispute

Astronics won a favorable UK appellate ruling in its patent infringement dispute with Lufthansa Technik.

• The court dismissed Lufthansa Technik’s appeal against the February 2025 damages judgment.
• One Astronics appeal succeeded, requiring Lufthansa Technik to partially refund damages previously paid; the amount remains to be determined.
• The decision also opens the door to additional attorney-fee awards tied to certain parts of the case.
• Either side can seek a further appeal to the UK Supreme Court, though acceptance is uncertain.
