AngioDynamics Comments on Declaratory Judgment Decision by Court.

QUEENSBURY, N.Y. -- AngioDynamics, Inc. (NASDAQ:ANGO) today commented on a decision in the U.S. District Court for Delaware concerning a declaratory judgment action brought by AngioDynamics against Diomed, Inc. This case is unrelated to the ongoing litigation brought by Diomed against AngioDynamics and others regarding the '777 patent.

On September 7, 2006, U.S. District Judge Gregory Sleet denied AngioDynamics' request to bring a declaratory judgment action against Diomed regarding two patents (U.S. patent numbers 6,981,971 and 6,986,766) recently issued to Diomed. These patents relate to a medical device and method that includes graduated markings along a sheath. AngioDynamics brought this case in January 2006, due to concerns that Diomed would wrongly sue AngioDynamics for infringement, in particular regarding the AngioDynamics VenaCure product. If the court had granted the request, the case would have proceeded to trial, providing AngioDynamics with an opportunity to prove these patents are invalid. Rather than hearing the case, the court denied AngioDynamics' request to bring action at this time, stating that, under the circumstances, there was not sufficient evidence of a threat of litigation by Diomed, thus there was no basis for allowing the case to proceed.

"While we are disappointed that the court chose not to hear this case at this time, we are very confident that if any action is initiated against AngioDynamics by Diomed regarding these patents, the patents will be proven invalid in light of very significant prior art and other factors," commented Eamonn P. Hobbs, president and chief executive officer of AngioDynamics.
