On January 12, 2005 ZENON Environmental Inc. filed further action against U.S. Filter Corporation. The action alleges infringement of its Patent No. 6,682,652 directed at an apparatus for withdrawing permeate using an immersed hollow fiber membrane.
The most recent action comes after a court ruling, mentioned in ZENON’s November 9, 2004 news release. ZENON noted in the release that it intends to appeal the ruling at the first appropriate opportunity and is confident of success. In any event, the patent that is the subject of the newly filed action has claims that are not subject to the issues raised in the above ruling.
ZENON filed its original suit against U.S. Filter Corporation in October 2003. The company is seeking damages and an injunction to stop the sale, manufacture and use of US Filter’s MemJet and CMF-S products that infringe ZENON’s intellectual property, protected by patents issued in the U.S.
ZENON continues to vigorously pursue its efforts regarding the suit and has not dropped its claims for monetary damages or infringement, although U.S. Filter has already ceased to practice the invention claimed in one of the patents.
