Active8media, a firm that helps print publications create interactive versions of the ads in their pages, sued Conde Nast for both patent infringement and trade secret misappropriation, according to MediaWeek. Conde Nast used Active8media's technology for its September 2004 Vogue issue, but started using another firm's similar technology subsequently. That firm, RichFx, is now accused of using Active8media's patents and trade secrets - two very different forms of intellectual property, which will likely be treated rather differently - for Conde Nast Traveler's most recent March and May issues.
