CTB, Inc. v. Hog Slat, Inc., No. 18-2107 (4th Cir. 2020)Annotate this Case
Plaintiff appealed the district court's grant of summary judgment in favor of defendant on the grounds that plaintiff's trade dress registrations, which cover the shape and color scheme of its chicken feeder products, are functional and thus only eligible for patent law's protection of utilitarian inventions.
The Fourth Circuit affirmed the district court's grant of summary judgment to defendant on plaintiff's claims of trade dress infringement under the Lanham Act and North Carolina common law. The court held that the total feeder profile is functional and ineligible for trade dress protection. The court explained that, because the color trade dress was placed on the supplemental trademark register, rather than the principal register, it is presumed functional, and plaintiff bears the burden of proving non-functionality. In this case, the court held that plaintiff cannot do so because its own utility patents and witness testimony establish that the red pan and gray spokes serve the functional purpose of attracting chickens to feed. Finally, the court held that the district court's order recommending a trial sanction for spoliation of evidence was moot.
