Wella, the German maker of haircare products, cosmetics and perfumes, said Thursday it has filed lawsuits against the Italian luxury goods maker Gucci in a dispute over the length of a perfume licensing contract. Wella and Gucci disagree over how long the German company can make perfumes and fragrances under the Gucci brand, a spokesman for Wella's Cosmopolitan Cosmetics unit said. The German firm believes it has a 50-year contract to develop, produce and sell Gucci fragrances including Rush, Envy, Accenti, Nobile or Eau de Gucci, while the upscale French-owned Gucci claims the contract ran out in 2003. Lawsuits have been filed simultaneously in New York, Milan and Cologne, but Wella said it was keen to reach an out-of-court settlement. Wella's fragrances division, which employs more than 2,500, is one of the company's strongest performing businesses. It accounts for about a quarter of total Wella sales.
