AngioDynamics Announces Latest Ruling in VNUS Litigation.

Trial Date Postponed Due to Busy Court Calendar

QUEENSBURY, N.Y. -- AngioDynamics (NASDAQ:ANGO) announced today that the October 29 trial date in the patent litigation brought by VNUS Medical Technologies against AngioDynamics, Diomed and Vascular Solutions has been postponed due to scheduling conflicts in the court. No new trial date has been set.

Judge Maxine Chesney of the U.S. District Court in the Northern District of California also denied the defendants' motion that two of VNUS's patents are invalid due to prior art, leaving these issues for trial.

In a ruling earlier this month, the Judge denied VNUS's motion for summary judgment of infringement, leaving that issue for trial. The court also denied defendants' motion that another of VNUS' patents was invalid in light of the prior art, as well as the invalidity of all asserted patents for non-compliance with the written description and enablement requirements of the Patent Law, leaving these issues for trial as well.
