PRNewswire reports that DuPont has filed a patent infringement lawsuit against MacDermid, Inc. and MacDermid Printing Solutions, L.L.C. on U.S. patents relating to its DuPont™ Cyrel® FAST technology. The suit was filed in federal court in Denver, Colo. DuPont claims MacDermid has manufactured, used, offered for sale and sold flexographic plates, including products marketed under the names Magma and MLT, that are covered by a DuPont U.S. patent related to thermal flexographic technology. The suit also claims that MacDermid has actively induced others to infringe on another DuPont U.S. patent through offers to sell, advertise and promote thermal flexographic printing systems. DuPont is seeking monetary damages and demanding that MacDermid stop further acts of infringement associated with these products.
