Pall Corp., which makes filters and purifiers, said late Thursday it received a favorable claim construction ruling in a patent infringement lawsuit against a 3M Co. division. The lawsuit claims Cuno Inc.'s Polypro XL and LifeAssure filters infringe two patents related to Pall's Ultipleat filters, which use a laid-over pleat design that allows more material to be packed into a smaller envelope. U.S. District Judge Joanna Seybert of the Eastern District of New York stated Wednesday in a memorandum and order that Pall's product "was a major breakthrough" when it was created, as it established a more efficient and long-lasting filter without increasing the size of the product. Pall is seek compensatory damages and a permanent injunction against Cuno selling the products named in the lawsuit. The court ruled in 2002 that an earlier Cuno product infringed on the same patents, Pall said.
