Executive Summary
A US court of appeals has upheld a previous ruling stating that Cook did not infringe Edwards Lifesciences' patents related to endovascular devices for treating aneurysms. This is the latest development in a case that dates back to 2003, when Edwards first kick-started the legal dispute, claiming that four of Cook's Zenith endovascular stent-grafts infringed its patents. The two companies are also involved in other courtroom battles, both in and outside the US, concerning patents relating to transcatheter valve technology (www.clinica.co.uk, March 23 and June 15 2009).
