A New York state appeals court has allowed to go forward a $15 million legal malpractice action against lawyers who’d represented an internet gaming company in a previous legal malpractice suit against the company’s attorneys who’d erred on a patent application.

In an extraordinary series of events and lawsuits involving the company Protostorm, the latest ruling is that the company can proceed with its malpractice lawsuit against Foley & Lardner and intellectual property partner Jonathan Moskin, because Foley and Moskin, after winning a 2014 federal malpractice trial on Protostorm’s behalf, allegedly waived joint and several liability against two individual attorney defendants.
