SUPERCONDUCTOR TECHNOLOGIES INC. WINS
COURT RULING ON ‘215 PATENT INFRINGEMENT LAWSUIT

SANTA BARBARA, CA — April 3, 2003: Superconductor Technologies Inc. (Nasdaq:
SCON) (“STI”) the global leader in high-temperature superconducting (HTS)
products for wireless voice and data applications, today announced the jury has
rendered its verdict in the patent infringement lawsuit brought by ISCO
International, Inc. (“ISCO”), filed on July 17, 2001 in the United District
Court for the District of Delaware.

The jury returned a unanimous verdict that ISCO’s US patent 6,263,215 for
“Cryoelectronically Cooled Receiver Front End for Mobile Communications System”
(the “‘215 Patent”) is invalid and unenforceable. In addition, the jury awarded
STI $3.8 million in compensatory damages based upon a finding that ISCO
committed unfair competition and acted in bad faith by issuing press releases
and/or contacting STI’s customers asserting the ‘215 Patent.

M. Peter Thomas, STI’s president and chief executive officer stated, “It has
always been our firm belief that the ‘215 patent is invalid. We are very pleased
with the outcome of the trial, and we look forward to getting back to business
as usual.”
