The Associated Press reports, a federal jury in Texas has ordered Johnson & Johnson and a subsidiary to pay $482 million in damages to an inventor who claimed the health care giant infringed on his patent for a cardiac stent. Jurors hearing the case in the U.S. District Court for the Eastern District of Texas deliberated for two hours before returning the verdict against Johnson & Johnson and Cordis Corp. The dispute centered over Cordis'' Cypher drug-eluting stents, which release a drug to help keep arteries from becoming blocked. Bruce Saffran, a doctor from Princeton, N.J., sued the two companies in 2007, claiming the Cypher stents infringed on his 1997 patent covering technology to deliver injury-healing medication inside the body. Jurors concluded that Saffran proved that the Cypher stents infringed on his patent and that Johnson & Johnson and Cordis did so willfully.
