AngioDynamics Settles Patent Lawsuit Against Vascular Solutions

AngioDynamics Inc., a maker of devices to treat blood-vessel diseases, agreed to settle its patent fight with Vascular Solutions Inc. over a varicose vein treatment, court records show.

Terms weren’t disclosed in the Dec. 21 joint court filing announcing the settlement of all claims and counterclaims. The case was dismissed Dec. 23 by U.S. District Judge Donovan Frank in St. Paul, Minnesota, at the two companies’ request.

AngioDynamics, based in Latham, New York, sued in July 2009, claiming Minneapolis-based Vascular Solutions’ Vari-Lase product infringed two patents related to equipment and methods of treating varicose veins with internal lasers. As part of the settlement, the companies agreed that both patents are valid and enforceable, according to the court filing.

AngioDynamics wouldn’t comment on the settlement, saying the terms are confidential.

The case is AngioDynamics Inc. v. Vascular Solutions Inc., 100-3601, U.S. District Court for the District of Minnesota (St. Paul).
