Marc Denis Haefner: Attorney with Walsh Pizzi O'Reilly Falanga LLP
Attorney Awards


Marc D. Haefner, a partner in the firm, represents clients in a wide range of complex commercial and intellectual property litigation. As a commercial litigator, he specializes in civil cases arising under the Racketeer Influenced and Corrupt Organizations Act (RICO), and has both successfully prosecuted and defended such cases. He has also defended numerous class actions brought under New Jersey’s Consumer Fraud Act. His intellectual property work consists mainly of trademark, copyright infringement, and trade secret litigation in federal court.

In his 20 years of legal experience, Marc has also taken numerous appellate cases to successful conclusions. His appellate work has run the gamut from First Amendment cases involving religious liberty to issues of first impression on New Jersey’s Construction Lien Law. He has taken cases to appellate courts both when the firm represented the client below and when the case has been taken initially as an appellate matter.

Marc earned his J.D., magna cum laude, from Notre Dame Law School, where he worked as the research assistant to Professor G. Robert Blakey, the recognized drafter of the RICO statute, and served as Conflicts Editor for the Journal of Legislation. After graduation, Marc clerked for the Honorable Harold A. Ackerman in the United States District Court for the District of New Jersey. In his previous position at a major New Jersey law firm, he chaired the firm’s Pro-Bono Committee and supervised cases involving prisoners’ rights, protection of landmark buildings, and the appropriate scheduling of marijuana in New Jersey.
