Guidant Wins Decision in Heart Failure Device Patent Case

District Court for Delaware Upholds Validity of Mirowski Patent

Indianapolis, Ind. - Guidant Corporation (NYSE: GDT) today announced that it won a key decision in a heart failure device patent case against Medtronic, Inc. The Federal District Court for the District of Delaware has upheld the validity of U.S. Patent RE38,119 (''119 patent), which relates to cardiac resynchronization therapy and bi-ventricular pacing therapy. Guidant has exclusively licensed this patent from Mirowski Family Ventures, LLC, the entity that holds the patent rights of Dr. Michel Mirowski, inventor of the implantable defibrillator.

"This ruling reflects the strength and breadth of Guidant''s cardiac rhythm management intellectual property portfolio," said Fred McCoy, President, Cardiac Rhythm Management, Guidant Corporation. "We are proud to be stewards of the Mirowski patent portfolio."

On August 29, 2003, Medtronic, a licensee of the ''119 patent, challenged its obligation to pay royalties to the Mirowski family by filing suit to have the patent declared invalid. The District Court decision yesterday upheld the patent''s validity.
