EAST HILLS, N.Y.--(BUSINESS WIRE)--Pall Corporation (NYSE:PLL) announced that the United States District Court, Eastern District of New York yesterday issued a favorable claim construction ruling in a patent infringement lawsuit against Cuno Inc, a 3M company (NYSE:MMM). This ruling reinforces Pall’s position that Cuno infringes the patents in suit and undermines Cuno’s invalidity and unenforceability defenses. Pall seeks compensatory damages and a permanent injunction precluding Cuno from selling its infringing products. In 2002 the same Court ruled that an earlier Cuno product infringed the same patents.
