Last week, design firm Tony Duquette Inc. handed J. Crew Group Inc. with a lawsuit claiming the retailers' leopard-print cardigan was unfairly used knowingly and willfully which went against trademark rights. The lawsuit filed in New York said J. Crew promoted and sold a women's "Duquette Leopard Print Sweater" with no permission. During the fifties, Duquette used his signature leopard print designs for several items such as fabrics, wallpaper, carpet, clothing and furniture. Below is a photo of the "Duquette Leopard Print Sweater" from J. Crew, a photo of the original Duquette design and a picture of Duquette himself and his wife during the fifties.
