MacDermid files patent infringement lawsuit against DuPont

As part of ongoing efforts to protect its intellectual property, MacDermid has announced that it has filed a patent infringement lawsuit against DuPont on a US patent relating to its digital photopolymer plate technology.

In this lawsuit MacDermid claims that DuPont has manufactured, used, offered for sale and sold flexographic plates, including products marketed under the name DFH 45, DFM 45, DFM 67and DPR 67, that are covered by a MacDermid US patent related to digital photopolymer plate technology. This suit also claims that DuPont has actively induced others to infringe through offers to sell, advertise and promote digital photopolymer plates.

MacDermid is seeking monetary damages and demanding that DuPont stop further acts of infringement associated with these products.

‘MacDermid has made a substantial investment in developing its digital technologies and must protect this very important intellectual property,’ said Dr Timothy Gotsick, director of innovation at MacDermid.
