QUEENSBURY, N.Y.--(BUSINESS WIRE)--AngioDynamics, Inc. (NASDAQ:ANGO) today announced the denial of cross-motions for summary judgment issued in the U.S. District Court in the Northern District of California in the patent litigation brought by VNUS Medical Technologies against Diomed, AngioDynamics and Vascular Solutions.
In her ruling, Judge Chesney denied VNUS's motion for summary judgment of infringement, leaving that issue for trial. The court also denied defendants’ motion that one patent was invalid in light of the prior art, and invalidity of all asserted patents for non-compliance with the written description and enablement requirements of the Patent Law, also leaving these issues for trial. The Judge deferred ruling on the defendants' motion that two of VNUS's patents are invalid due to prior art, asking VNUS to respond to issues raised by the defendants by October 19.
