The District Court of Dusseldorf

The OEM has filed two suits against the companies in Germany for infringing a patent relating to a drum unit and process cartridge.

The OEM reported that it has today filed two patent infringement suits in Germany at the District Court of Dusseldorf against wta Carsten Weser GmbH and KMP PrintTechnik AG for “infringement of the German portion” of a European patent covering drum units in toner cartridges.

The European patent, EP 2 087 407, refers to a “drum unit and a process cartridge”, with the infringement suit covering “inter alia, the manufacturing, offer and sale of certain toner cartridges for use in various models of Canon and Hewlett-Packard German laser beam printers”. The OEM stated that it is “seeking injunctive relief and damages”.

The OEM released a statement in line with its other patent infringement announcements, commenting that “throughout the development, sales and marketing process, Canon respects the intellectual property rights of other companies and individuals and expects others to do the same. Canon remains committed to taking legal action against anyone who does not respect Canon’s intellectual property rights”.

The OEM has recently begun legal actions against supposed patent infringement in Europe, with a case begun in Holland against Aster Technology in April adding Seine Holland this month, and its US IP case saw a new action undertaken at the United States International Trade Commission (USITC).
