New Haven-based Wiggin and Dana has announced that it is adding attorneys to both its white-collar defense and its intellectual property teams.

David Ring, the former Global Director of Compliance Investigations for United Technologies Corp. and a former federal prosecutor, joins Wiggin as a partner in the firm’s New Haven and Hartford offices.

Ring’s practice will focus on white collar criminal defense, internal investigations, corporate compliance, and complex civil litigation. His expertise covers issues relating to public corruption; fraud involving banks, health care and government contracts; and the Foreign Corrupt Practices Act.

“David is a tremendous asset to our firm with his significant prosecutorial and Fortune 50 compliance experience,” said Bob Benjamin, chair of the firm’s Executive Committee.

Litigation Department chair Jim Glasser added: “Wiggin and Dana’s White Collar practice has experienced tremendous growth. With the addition of David, our team will be enhanced owing to his significant trial and compliance experience and familiarity investigating matters as both a corporate lawyer and former federal prosecutor.”

As UTC’s Global Director of Compliance Investigations, Ring was responsible for leading investigations worldwide, liaising with law enforcement, implementing compliance policies and controls, and coordinating the compliance leaders in UTC’s business units.

Wiggin and Dana also announce that it has added four new IP partners to its New York office. Joseph Casino, Michael Kasdan and Abraham Kasdan all previously practiced with Amster, Rothstein and Ebenstein, while Sapna Palla previously worked at Kaye Scholer.

“Based on current and projected client demand, we targeted intellectual property as an especially promising growth area for the firm,” said Bob Benjamin, chair of Wiggin and Dana’s Executive Committee. “With the addition of this dynamic group, we have greatly enhanced our ability to provide a wide range of IP services to our clients, from intellectual property litigation to licensing and prosecution.”
