Wolf Greenfield Client Diomed Holdings Wins $12.5 Million Award in Patent Case

Jury Finds Two Defendants Infringed Patent for Varicose Vein Treatment


BOSTON, MA -- (MARKET WIRE) -- March 29, 2007 -- A jury awarded Diomed Holdings, Inc. $12.46 million in patent-infringement damages from two defendants, AngioDynamics, Inc. and Vascular Solutions, Inc. Diomed was represented by Wolf, Greenfield & Sacks, P.C., a Boston intellectual property law firm.

In its verdict on March 28 in the federal court in Boston, the jury found each defendant liable for both inducing infringement and contributory infringement of Diomed's U.S. Patent No. 6,398,777.

Diomed, developer of the patented laser treatment method for varicose veins, will now seek to obtain a permanent injunction against both infringers, according to Michael Albert, who heads Wolf Greenfield's litigation practice.

The jury trial followed a summary judgment ruling last summer that Diomed's patent is valid and enforceable.

"We're delighted for our client and proud of our litigation team who worked long and hard on this case," Albert said.

Andover, Mass.-based Diomed develops and commercializes minimal and micro-invasive medical procedures that use its proprietary laser technologies and disposable products. Diomed's EVLT® laser vein ablation procedure is used in varicose vein treatments.
