Two ex-clients of Boies Schiller Flexner filed a lawsuit in New Jersey Superior Court alleging that firm founder David Boies and Washington, D.C., partner Michael Underhill committed legal malpractice and breached fiduciary duties as counsel, among other allegations.

The lawsuit, by New Jersey-based companies Telebrands Corp. and Bulbhead.com, alleges that repeated mistakes in IP litigation against competitors Tinnus Enterprises and Zuru Limited over a similar product resulted in a multimillion-dollar judgment against Telebrands and Bulbhead.com, and a subsequent confidential settlement with Tinnus.
