This Lanham Act case turns on whether the shape and design of a small bag, modeled after a men’s Dopp Kit and used in personal care kits, are functional and therefore not protected as trade dress. Plaintiff sells personal care kits in such a bag. When another personal care kit seller copied plaintiff’s bag, plaintiff sued, claiming the bag was protected trade dress. The district court granted summary judgment in defendant’s favor, finding that the bag’s design and shape were functional. We agree, so we affirm the district court’s decision.
