This suit, while part of the collection, is not an antitrust case. Catamore Enterprises, a jewelry manufacturer and distributer, was sued by IBM for non-payment on a contract. The issue here was a dispute over contract fulfillment, marketing strategy and product suitability. It would appear that CCIA included this case among the antitrust litigation, because it was seen to demonstrate some of the arguments about IBM's market behavior that were central issues in the government's and the other civil cases.
