Court Sets Trial Date in Diomed EVLT Patent Litigation

ANDOVER, Mass.--(HSMN NewsFeed)--Diomed Holdings, Inc. (AMEX: DIO ), a leading developer and marketer of minimally invasive medical technologies, including its patented EndoVenous Laser Treatment (EVLT(R)) for varicose veins, today announced that U.S. District Judge Nathaniel M. Gorton has set March 12, 2007 as the trial date for commencement of trial in the pending litigation to enforce Diomed's U.S. Patent No. 6,398,777 against both AngioDynamics and Vascular Solutions.

In January 2004, Diomed commenced legal action in the United States Federal District Court for the District of Massachusetts against AngioDynamics, seeking injunctive relief and damages for infringement of Diomed's pioneering United States Patent Number 6,398,777 which covers the endovascular laser treatment of varicose veins. Diomed acquired exclusive rights to the patent from the five inventors of the procedure in September 2003. Diomed initiated similar infringement actions against Vascular Solutions and two other competitors later in 2004.

In August of this year Judge Gorton ruled that Diomed's '777 patent is both valid and enforceable, limiting the issues to be heard at trial to infringement and damages. Specifically, in addition to injunctive relief and recovery of legal costs, Diomed intends to seek direct damages of approximately $17.4 million. Additionally, should the jury find the defendants "willfully" infringed on Diomed's patent, any award could be subject to treble damages.

"We are pleased with the date that the court has chosen and look forward to proceeding to trial," stated James A. Wylie, Jr., President and Chief Executive Officer of Diomed Holdings, Inc. "Having invested nearly $10 million in the acquisition and litigation of our EVLTŪ intellectual property, we fully intend to protect our patent against those who infringe upon Diomed's legal rights. We look forward to seeing this case to its just and timely conclusion."
