Delay in Start of VNUS Medical Technologies Patent Litigation and Court Ruling on Summary Judgment Motion

SAN JOSE, Calif., Oct. 22 /PRNewswire-FirstCall/ -- The start of the patent lawsuit by VNUS(R) Medical Technologies, Inc. against three endovenous laser competitors, Diomed, AngioDynamics and Vascular Solutions, has been delayed from a previously scheduled start date of October 29. The delay is due to a busy court calendar. A court conference is scheduled for October 26 to identify potential new trial start dates. At the conference, the parties will seek to have the trial start during the first quarter of 2008.

In addition, the judge today issued a ruling denying defendants’ summary judgment motion that asked to declare two of VNUS’ patents invalid. Accordingly, the case will proceed to trial on all three of the patents that VNUS seeks to enforce.
