California Computer Products, Inc. v. International Business Machines Corp.
United States Court of Appeals for the Ninth Circuit
613 F.2d 727 (1979)
Relevant factsFree
CalComp (plaintiff) manufactured peripheral computer components compatible with IBM's (defendant's) mainframes; when IBM released a new computer line integrating peripherals like disk drives and memory directly into the central unit at a lower combined price than the separate components, CalComp's market for standalone peripherals shrank, and CalComp sued IBM for monopolization under Sherman Act § 2. The district court found for IBM, and CalComp appealed.
IssueFree
Whether a monopolist violates antitrust law simply by redesigning its product to integrate previously separate components and lowering the resulting price.
