Cook Medical Remains Resolute in Pursuit of Infringement Action Against Endologix Following Markman Ruling

Bloomington, Ind. – Cook Incorporated, a global leader in endovascular technologies, announced today that Judge Tanya Walton Pratt of the United States District Court for the Southern District of Indiana in Indianapolis has issued a Markman ruling in the ongoing patent infringement lawsuit filed against Endologix (Nasdaq: ELGX). The majority of constructions adopted by the Judge favored Cook’s proposed constructions.

“Cook has never wavered in the protection of its extensive patent portfolio,” said Cook general counsel Cynthia Kretz. “We will move forward as swiftly as possible to obtain all available remedies based on Endologix’ infringement of our two patents.”

The two patents in suit are Cook’s U.S. Patent 5,755,777 and 5,035,706. The ‘777 Patent “Expandable Transluminal Graft Prosthesis for Repair of Aneurysm” was granted on May 26, 1998. The ‘706 Patent “Percutaneous Stent and Method of Retrieval Thereof” was granted on July 30, 1991.
