Endologix questions patents' validity in Cook lawsuit
This article was originally published in Clinica
Endologix is attempting to discontinue a lawsuit filed against it by Cook, or at least to delay it so that the latter’s patents covering endovascular technology can be re-examined. Bloomington, Indiana-based Cook originally accused Endologix of infringing one patent that covers its expandable transluminal graft prosthesis for the repair of aneurysms and another that covers the retrieval of percutaneous stents. The litigation seeks to gain damages and to enjoin Endologix from selling all products that infringe these patents (www.clinica.co.uk, October 13 2009). Endologix (Irvine, California) has filed a motion in the US district court of Indianapolis asking for the US Patent and Trademark Office (USPTO) to re-examine the patents and determine whether or not the patents should have been granted in the first place. The firm has also filed papers arguing that its devices do not violate Cook’s patents.
