Astronics Corporation (NASDAQ:ATRO), a leading provider of advanced technologies for global aerospace, defense and other mission critical industries, announced today that a favorable judgment has been issued by the UK appellate court presiding over its long-running patent infringement dispute with Lufthansa Technik AG.

Lufthansa Technik had filed an appeal of the trial court’s February 2025, judgment on damages, and Astronics had filed three appeals. The UK appellate court dismissed in its entirety Lufthansa Technik’s appeal, and granted one of Astronics’ appeals, which will require Lufthansa Technik to make a partial refund to Astronics of damages previously paid, in an amount yet to be determined. Additional amounts may be payable to Astronics for attorney fees associated with certain elements of the case, based on the court’s decision.

Either party may request an appeal of the appellate court’s decision to the UK Supreme Court, though it is uncertain if the Supreme Court will choose to hear any further appeals.
