An appeals court has shot down Bell Helicopter Textron’s claims against Iran.

In a 19-page decision Friday, the U.S. Court of Appeals for the District of Columbia Circuit upheld a trial judge’s earlier ruling siding with Iran. The trial judge had vacated a default judgement against the country concerning the manufacture and marketing of a helicopter that resembles Bell’s Jet Ranger 206.

As summarized by the appeals court, “in the 1970s, Bell operated a helicopter plant in Iran, which it abandoned after the Iranian revolution of 1979. In December 2002, Bell became aware that the Iran Aircraft Manufacturing Industrial Company, a company wholly owned and controlled by the Iranian government, was using the plant to manufacture helicopters that resembled the Jet Ranger 206.”
