Anheuser-Busch has won a partial claim against Crown Cork & Seal. A federal appeals panel has sent part of a patent dispute between A-B and Crown back to a lower court for reconsideration.

The panel said that the reasoning behind the decision that the beer maker did not violate a can manufacturing process was faulty.

The opinion yesterday (23 December) from the US Court of Appeals for the Federal Circuit also affirmed that A-B did not violate a separate Crown Cork can patent.
