The United States District Court for the Eastern District of Pennsylvania ruled this week that sales by Q.I. Press Controls (QIPC) are not to be restricted during a patent-infringement trial.
The case, for which no trial date has been set, arose from last June’s complaint by Quad/Graphics subsidiary QuadTech Inc. that QIPC’s markless register control (mRC) infringes QuadTech’s U.S. Patent 5,412,577 from 1992 in both mark and markless mode.
A year before QuadTech filed its U.S. suit, a district court in D?sseldorf found QIPC had infringed a related patent in Germany and enjoined QIPC from selling its mRC in that country — a ruling upheld on appeal several months later.
