On June 12, the U.S. Court of Appeals for the Seventh Circuit decided Bodum USA, Inc. v. A Top New Casting Inc., No. 18-3030, 2019 (7th Cir. June 12, 2019). The case was based on Bodum’s allegation that A Top infringed Bodum’s unregistered trade dress in its Chambord® French press coffee maker design and squarely addressed the doctrine of “functionality” of trade dress. The court addressed two important issues related to functionality: (1) what type of evidence is necessary to prove functionality of a particular design and (2) under what circumstances are utility patents relevant to that analysis?
