Crater sued Lucent for missappropriation of trade secrets related to an under-sea fiber-optic coupling device. The government intervened to assert the 'state secret' privilege because divulging the information Crater requested during discovery would jeopardize national security. The C.A.F.C. affirmed the invocation of the state secrets privilege. However, the C.A.F.C. remanded for a determination of whether Crater may establish any claims without relying on the privileged information.
