Medtronic Loses Patent Lawsuit against BrainLAB

US Court of Appeals for the Federal Circuit has upheld the US District Court for the District of Colorado judgment to dismiss the patent infringement lawsuit filed by Medtronic against BrainLAB in 1998, affirming the district court ruling that BrainLAB image-guided surgery and radiotherapy products do no infringe any of the patents in suit (US Patent Nos. 4,722,056; 5,386,454; 5,389,101 and 5,603,318). In February 2006, the US District Court dismissed Medtronic’s patent infringement lawsuit, finding that BrainLAB products do not infringe any of Medtronic’s patents in suit. The district court concluded that a September 2005 jury verdict, where the jury found that BrainLAB infringed four patents held or licensed by Medtronic and awarded Medtronic US $ 51 million, was is error and not supported by the evidence.
