Case Facts & Court Holding
Key Facts & Case Background
Levi Strauss & Co. (“Levi’s”) holds an incontestable federal trademark for its “arcuate” back pocket stitching pattern, used since 1873 and strongly associated with its brand. Lois Sportswear, U.S.A., Inc. (“Lois”) began selling jeans with a nearly identical arcuate stitching pattern. While Lois’s jeans featured their own prominent labels and hangtags, Levi’s argued this was insufficient to prevent trademark infringement. The district court granted summary judgment for Levi’s, finding a likelihood of confusion. Lois appealed, arguing its labeling prevented any confusion at the point of sale and that summary judgment was inappropriate. The core dispute centered on whether the similar stitching, viewed in a post-sale context (e.g., on a person in public) or as suggesting a business affiliation, constituted infringement despite the presence of Lois’s own branding at the time of purchase.
