This is an appeal from a grant of summary judgment in favor of defendants Unique Industries, Inc. and Everett Novak (collectively "Unique") in this copyright infringement action brought by Masquerade Novelty, Inc. The district court held that the relevant products made by Masquerade, masks configured to resemble the noses of a pig, elephant, and a parrot respectively, were "useful articles" under 17 U.S.C. § 101 and were not copyrightable because their sculptural elements could not be separated from their utilitarian purpose of allowing a person to create humor by masquerading in an animal's nose. Thus, it entered judgment for Unique on Masquerade's complaint. We find that because the only utilitarian function of the nose masks is in their portrayal of animal noses, the district court erred in concluding that they were not copyrightable.
