Biography

Sig Wissner-Gross represents a wide variety of clients in complex business litigations. While Sig is resident in Brown Rudnick’s New York office, he has handled cases in over fifteen different jurisdictions around the country.

Sig frequently serves as lead litigation counsel on behalf of creditors and ad hoc creditor groups in high profile cases, many of them in the Delaware Courts. He has successfully prosecuted as lead trial counsel numerous major cases in Delaware Chancery Court, obtaining summary judgment for his client (Indenture Trustees acting at the direction of bondholders) in several of them, and settling another case for nearly $2 billion. Furthermore, Sig has significant experience litigating fraudulent transfer and other claims in the bankruptcy courts. 

Sig also regularly serves as counsel in the prosecution of other high profile and fast moving litigations. He negotiated on behalf of a client the settlement of claims exceeding $123 million asserted against the world’s largest food servicing business in a closely followed RICO case filed in the Southern District of New York arising out of an alleged bid-rigging scheme at the United Nations.

Many of Sig’s cases involve complex multi-party discovery, in which Sig has supervised a team of attorneys and depositions across the country have been taken. He has been lead counsel in numerous major cases asserting claims for professional liability against financial institutions, auditors and other professionals. He also has successfully represented private and public companies (along with their officers and directors) in the biotech, pharma, telecommunications, and media & entertainment industries, as well as prominent individuals, brokerage firms and other clients.

In addition to his litigation expertise, Sig is often asked by corporate clients to conduct internal investigations and to provide pre-litigation advice. He also has substantial arbitration experience (e.g., before the AAA, FINRA, the CPR, and international arbitration forums), and is well-known as a leading attorney in alternative dispute resolution proceedings (including pre-litigation and pre-trial mediation).
