Berkey Photo, Inc. v. Eastman Kodak Co.
United States Court of Appeals for the Second Circuit
603 F.2d 263 (1979)
Eastman Kodak (defendant) held a monopoly in camera film and a dominant camera-market share, and in 1972 simultaneously launched the 110 camera and Kodacolor II film, each compatible only with the other, giving Kodak's competitors, including Berkey Photo (plaintiff), no advance notice and no time to develop competing compatible products; Berkey's rushed competing camera suffered design defects. Berkey sued, claiming Kodak's simultaneous product launch and refusal to share advance technical information impermissibly used its film monopoly to seize the camera market.
Whether a monopolist violates the Sherman Act by declining to disclose a new product's technology to competitors before launch and by simultaneously introducing two compatible, mutually exclusive new products.
