A federal judge Wednesday largely denied a motion to dismiss a $100 million malpractice case against Greenberg Traurig stemming from its patent work for an electronics manufacturing client.

The bench ruling by Southern District of New York Judge George Daniels cleared the way for discovery to begin in Leviton Manufacturing Co. Inc.’s suit against the firm. Leviton sued Greenberg and three of its former partners in September after a District of Maryland magistrate judge found that Leviton, while represented by Greenberg, had committed “inequitable conduct” before the U.S. Patent and Trademark Office and had committed discovery abuses in subsequent litigation.
