This comes on the heels of the Patent Office’s decision in April, 2008 to allow Vnus a separate patent application, also filed as a continuation of one of the patents in the lawsuit. Vnus has sued several endovenous laser manufacturers (Diomed, Angiodynamics, and Vascular Solutions) for infringement of Vnus patents. That lawsuit is currently scheduled to begin trial against non-bankrupt defendants Angiodynamics and Vascular Solutions on June 23, 2008.
The newly allowed Vnus patent application contains claims that recite methods of administering fluid around a hollow anatomical structure, such as a vein in a lower limb, and applying energy from an elongate member to the hollow anatomical structure.
Brian Farley, Vnus president and CEO, said: “The newly allowed claims provide additional, meaningful breadth to our patent position and will be a significant asset for protecting our endovenous ablation technology.”
