The U.S. Court of Appeals for the Third Circuit upheld a ruling that a settlement between the DeLorean Motor Co. and its founder’s estate precluded a suit seeking back royalties from products using the company’s images and logo.

“The question presented is whether the Settlement Agreement precludes the Estate’s claims in this action,” wrote Third Circuit Judge Joseph Greenaway Jr. in the Dec. 5 opinion. “The District Court found that it did, and the Estate appealed. … We will affirm.”
