The United States District Court for the Southern District of California has ruled that United States Patent No. 6,620,319 (the '319 patent), the subject of a patent infringement suit brought by ZENON against U.S. Filter, continues to be presumed valid. On October 8, 2003 ZENON filed a patent infringement action against U.S. Filter complaining of infringement of three ZENON owned patents relating to water treatment, most importantly, the '319 patent relating to membrane module construction. In the course of these proceedings, U.S. Filter among other things, alleged the invalidity of the '319 patent which if successful would have affected other patents in the same patent family. The parties recently agreed to a bench trial on the issue of the validity of the '319 patent. The trial was conducted in San Diego on April 27-28, 2005. A ruling from the Court was delivered on May 5, 2005 in which the Court ruled in favor of ZENON strongly refuting all of defendant U.S. Filter's contentions. ZENON CEO Andrew Benedek stated that "The decision clears perhaps the single most significant hurdle in our path toward proving our claims and our request for an injunction to stop infringement by U.S. Filter."
