Mary J. Hildebrand, Founder and Chair of Lowenstein Sandler's Privacy Practice Area, and senior Partner in the firm’s Tech Group, has more than 25 years of experience in strategic planning, commercialization, protection, and management of intellectual property, technology and database assets around the world. Mary has been lead counsel in many substantial transactions with particular emphasis on complex structures involving the development, distribution, exploitation, sale, license and outsourcing of intellectual property assets and web-enabled ventures. She regularly provides counsel regarding product distribution, marketing, dispute mediation, the acquisition and sale of technology companies and due diligence evaluations in the context of mergers, investments and venture capital transactions.

Mary counsels a broad array of clients including venture-backed companies in digital and social media, software, e-commerce and clean-tech; public companies and utilities in financial services, medical devices, entertainment, e-commerce, transportation and other industry sectors; and universities and not-for-profit organizations. She also serves as IP and privacy counsel in venture capital transactions and M&A transactions including, for example, the recent purchase of Buddy Media by Sales Force, and has in-depth experience handling privacy issues in the U.S. Bankruptcy Courts. Mary is currently a member of Lowenstein Sandler’s Board of Directors and Strategic Planning Committee, and chairs the firm’s Diversity and Inclusion Committee. Prior to joining Lowenstein Sandler, she was a partner at Goodwin Procter LLP, where she served as Chair of the firm’s IP Transactions & Strategies practice.

Recognized by Chambers USA: America's Leading Lawyers for Business (2009–2015) as a leading intellectual property attorney, Mary’s clients commend “Mary is a phenomenal client manager; she knows the area inside out; she’s hugely responsive and she knows exactly when to bring other expertise onboard.” “Mary gives useful, pragmatic, practical advice: stuff you can really use. She isn’t a partner who looks to hedge or caution advice and she’s not afraid to help you come to a decision.” Mary was also recognized by The Best Lawyers in America (2015) for her expertise in IT Outsourcing Law.

Mary is a founder and Co-chair of STRIDES®, Advancing Women in Business, an initiative sponsored by Lowenstein Sandler that promotes visibility, leadership opportunities, and quality peer interaction for women in business, and has been widely recognized for her efforts in this area. She is recipient of the Women's Political Caucus of New Jersey’s 2011 Mary Philbrook Award (named for the first woman admitted to the Bar in the State of New Jersey in 1896), given for her substantial contributions to the advancement of women in the legal profession. Mary was named one of the "Best Fifty Women in Business" by NJBiz magazine in 2011. She was also honored by the Executive Women of New Jersey, Salute to the Policy Makers, which in 2008 recognized her as one of the state’s leading women professionals who establish and implement strategic policy at major corporations, businesses and other organizations.
