Trade dress protects non-functional attributes of a product like color. %CUT% Moldex-Metric uses a bright green color for its foam earplugs. McKeon Products also uses bright green for foam earplugs. Moldex-Metric sued McKeon for infringement of unregistered trade dress, namely, the color of the earplugs. The trial court granted summary judgment for McKeon holding that the bright green color couldn’t be protected as trade dress because it served the function of making them easier to see during an inspection. The Ninth Circuit Court of Appeals reversed. The court held that the trial court failed to consider whether other colors would be just as visible. So the case is remanded back to the trial court to allow a jury to decide if the green color was not functional because of available alternatives.
