The case was filed on March 5, 1997 in the United States District Court for the Eastern District of Pennsylvania, and is entitled Lucent Technologies, Inc. v. Aspect Telecommunications Corporation, (Civil Action No. 97-CV-1618). Aspect has developed its own technology for its call center products. Based upon its investigations to date, Aspect does not believe that it infringes any valid claims of the Lucent patents. Aspect has referred the complaint to its counsel for an appropriate response. Aspect's chairman and chief executive officer, James R. Carreker, stated, "Unfortunately, these types of actions have become fairly common among technology companies, some of whom are attempting to utilize their patent portfolios as an additional profit center. We intend to vigorously contest this complaint, while continuing to focus on building value for our customers, employees, investors, business partners and communities."
