Goliath, meet David.

In a case that has lasted nearly eight years and after a six-month trial in a New Jersey federal court, Tacoma-based Continuant has won a jury verdict against telecommunications giant Avaya.

The jury found that Avaya, a manufacturer of telecom equipment, violated antitrust laws. In its verdict, the jury awarded Continuant $20 million in compensatory damages. By law, the damages will be trebled to $60 million.

At issue was Continuant’s ability to offer repair and other customer services to owners of Avaya systems.

“When Avaya couldn’t beat us in the market place, they tried beating us with almost eight years of scorched-earth litigation,” said Continuant CEO and founder Doug Graham.

The eight-person jury found that Avaya violated antitrust law in its attempt to prohibit Continuant from providing post-warranty maintenance of Avaya telephone and predictive-dialer systems designed to serve large businesses, according to a Continuant release Thursday.

A spokesman for Avaya was unavailable Thursday.
