A 1995 article I found stated: "Oscar de la Renta Ltd, has resolved a dispute with an El Monte, Calif.--based firm called De Oscar Group Inc. that was infringing on its trademark...the New York-based de la Renta (CEO) first learned in August that the California company was using the De Oscar Collection, De Oscar Group, and Oscar name on labels for eveningwear." The article further notes the de la Renta firm hired intellectual property lawyers to press their infringement claim and the De Oscar party agreed to stop using any trademark or business name that could be confused with Oscar de la Renta.
