Little material from this trial has been preserved in this collection. Greyhound v. IBM is the only suit, of the cases represented here, involving a leasing company. The leasing company issue figures substantially in IBM's defense in Justice Department's suit and a number of important questions are raised about the nature of and activity in a marketplace where leasing companies play an influential role.

The suit, originally tried without a jury, was dismissed by the district court in 1972 with a directed verdict, after Greyhound concluded its argument of the case. Greyhound appealed the decision, and a 1977 ruling of the U.S. Court of Appeals found that some of the charges against IBM may be found valid by a jury, and a new trial was ordered by the court. IBM filed a brief with the U.S. Supreme Court arguing that the decision ordering a new trial would serve to intimidate competition, rather than foster it, and that the retrial was a burden to the lower courts. IBM's appeal was denied in January 1978. The second trial was set to begin on January 26, 1981. An out of court settlement was reached between Greyhound Computer Corporation and IBM on January 27, 1981. Greyhound received $17.7 million and withdrew its suit `with prejudice.'
