Two More Q.I. Press Controls Products Added to Patent Infringement Case

Sussex, WI--9 March 2010--QuadTech, the worldwide leader and innovator of press control technology, today has asked the U.S. District Court in Philadelphia to expand its patent infringement action against Q.I. Press Controls (QIPC) to assert infringement against two additional QIPC products: its Intelligent Register System (IRS) and Intelligent Density System (IDS). The U.S. action was started by QuadTech in June 2009, alleging that QIPC’s mRC register control system infringes on U.S. Patent 5,412,577. Today QuadTech moved to amend its complaint to assert that QIPC’s Intelligent Register System and Intelligent Density System also infringe the same QuadTech patent. The founders and owners of QIPC are former QuadTech employees.

According to QuadTech President Karl Fritchen, “Through the process of our ongoing litigation against Q.I. Press Controls, it became clear to us that they are infringing on QuadTech’s technology with not only their mRC system, but their IRS and IDS products as well.” Fritchen added, “We invest a lot of time, money and other resources in developing and enhancing our best-in-class technologies and will continue to protect our intellectual property to the highest extent possible.”

QuadTech recently succeeded in preventing Q.I. Press Controls from infringing a related patent in Germany. There the Court has prevented Q.I. Press Controls from marketing or otherwise selling its mRC system (also known as markless Register Control) in Germany. Q.I. Press controls accepted this judgment by the German court.
