HP Resolves Ink Cartridge Patent Infringement Dispute

PALO ALTO, Calif., July 19, 2007, HP today announced that it has resolved a patent infringement lawsuit against German-based InkTec GmbH Zentrale and PCE Group regarding inks used in the refilling of certain HP inkjet cartridges.

The settlement also included resolution with Korea-based InkTec Ltd., the manufacturer and distributor of the infringing products.

As part of the settlement, both InkTec entities and the PCE Group acknowledged the validity of the HP patents in suit and admitted to infringement. In addition, they agreed to pay HP an undisclosed sum, to stop selling infringing inks in Germany and other countries where such patents are held, and to withdraw infringing products from the market in those countries.

In October 2006, HP filed suit against InkTec GmbH Zentrale and the PCE Group in the District Court of Düsseldorf, Germany, after HP discovered that certain ink refill kits sold under the InkTec brand and distributed by InkTec and PCE Group contained infringing ink. HP asserted two patents relating to ink formulations and specifically accused InkTec refill kits used for refilling certain HP inkjet printer cartridges.

“HP will continue to invest in technology that benefits customers and to vigorously protect this investment,” said Michael Hoffmann, senior vice president, Supplies, Imaging and Printing Group, HP. “We’re pleased to have resolved this matter quickly without extensive litigation and will continue to monitor InkTec and others for possible patent infringement as part of our ongoing worldwide testing and enforcement efforts.”
