His litigation practice includes widely-publicized fraud and asset recovery cases on behalf of both creditors and debtors with damages in the hundreds of millions of dollars, cases of first impression in corporate veil-piercing and director and officer conduct, a landmark nationwide antitrust class action, consumer class action defense, and a wide variety of intellectual property matters.
