Pivot Point International sought copyright protection for a mannequin head created for it display hair pieces.  The District Court denied protection because the work was a useful article.  The Seventh Circuit reversed and remanded, stating that certain features of the mannequin were "conceptually separable" from the utilitarian aspects of the mannequin and were therefore entitled to copyright protection.  Pivot Point International Inc. v. Charlene Products Inc., Case No. 01-3888 (7th Cir. June 25, 2004).  The Court notes that trying to separate creative features from the utilitarian aspects of useful articles is one of the most "troublesome" distinctions in Copyright law.
