In the US, DuPont has reached an agreement with Cortron Corp to settle a patent infringement case involving DuPont’s Cyrel Fast thermal flexo printing plate technology.
Cortron will immediately cease manufacturing Lava thermal flexo plate processors and discontinue providing all service, spare parts, and technical support for any Lava equipment used to thermally develop flexo plates. Thermal processing equipment manufactured by Cortron has been marketed and sold by MacDermid Printing Solutions under the Lava trade name.
In May 2008, DuPont won an appeal in a patent infringement lawsuit against MacDermid “that MacDermid did not dispute infringement” of DuPont’s patent covering thermally developed flexo plates; and “that DuPont had shown a reasonable likelihood that MacDermid infringes one of DuPont’s patents”.
