Executive Summary
The patent row between Edwards Lifesciences and CoreValve has expanded into the US, after Irvine, California-based Edwards filed a suit against its rival in a district court in Delaware. Edwards kicked off the legal dispute in May 2007 by initiating a lawsuit against CoreValve in Germany, and shortly after in the UK. The row centres around a group of patents owned by Edwards, known as the Andersen patents, which relates to transcatheter heart valve technology. Edwards alleges that CoreValve's ReValving system, which is designed to replace heart valves in a minimally-invasive manner, infringes these patents and is seeking injunctive relief and damages.
