International Sales Aids (ISA) sold motivational brochures and flyers to Amway distributors, utilizing the Amway name and other Amway owned and trademarked product names. It sold these printed products to Amway distributors, who violated their distribution agreement with Amway by purchasing such products from a company other than Amway. The company sued, claiming that the use of the Amway name on products that directly competed with Amway unlawfully diluted their trademarks' value.
