AngioDynamics Announces That Court Denies Diomed's Summary Motion for Infringement

QUEENSBURY, N.Y.--(HSMN NewsFeed)--Aug. 31, 2006--AngioDynamics, Inc. (NASDAQ:ANGO ) today announced that the U. S. District Judge Nathaniel M. Gorton has ruled on summary judgment motions in the Diomed patent litigation in the Federal District Court in Massachusetts. In a sealed order dated August 30th, the Judge denied Diomed's request for summary judgment on patent infringement by AngioDynamics (the original complaint in this case) and also denied AngioDynamics' summary judgment motion of non-infringement, citing genuine issues of material fact. In defeating Diomed's motion, AngioDynamics pointed to the narrow scope of Diomed's patent and to the tenuous and circumstantial nature of its infringement claims. Separately, the Court granted Diomed's limited motion for summary judgment that its patent is valid and enforceable over certain prior art. As a result of the Judge's rulings, the case will now proceed to a jury trial. A trial date has not yet been scheduled by the Court.

In January 2004, Diomed, Inc., a subsidiary of Diomed Holdings, Inc., filed a lawsuit against the Company alleging patent infringement related to AngioDynamics' VenaCure(TM) product line. VenaCure is a laser system used for the treatment of severe varicose veins. The lawsuit involves a single U.S. patent, number 6,398,777, covering a specific method of endovascular laser treatment of varicose veins.

"While we are disappointed in the Judge's conclusion regarding the minor issues of validity and unenforceability, we are very pleased with the Court's construction of the patent claims and the views expressed on the issues of infringement. We look forward to successfully resolving this case at trial," commented Eamonn P. Hobbs, president and chief executive officer of AngioDynamics.
