THE PARTIES
F10. International Business Machines Corporation (IBM) was incorporated on February 24, 1924, and maintains its principal place of business in a state other than the State of Oklahoma where plaintiffs are incorporated and maintain their principal places of business. Before its entry into the electronic data processing (EDP) industry, IBM manufactured punched card accounting machines and other products. In addition to its EDP business, IBM develops, manufactures and markets other business machines including copiers, dictating equipment, and electric typewriters.

The first IBM 701 was completed in April of 1953 and was intended primarily for scientific work in connection with nuclear research. The first IBM computer intended for commercial work was the IBM 702, which was installed in early 1955.
