Mary J. Hildebrand, Founder and Chair of Lowenstein Sandler's Privacy and Information Security Practice, and Partner in The Tech Group, has more than 30 years of experience in bringing technology deals from conception to conclusion. Her deep experience converges at the intersection of privacy and data security, tech, and intellectual property. Mary routinely serves as lead counsel in complex commercial matters on behalf of companies — both public and private — across industries including digital and social media, software, clean-tech, renewable energy, public utilities, financial services, medical devices, entertainment, e-commerce, transportation, universities, and not-for-profit organizations. Her practice also encompasses the transactions and foundational legal structure needed by start-ups in the launch of their businesses.

Mary also has extensive experience in the commercialization, protection, and management of intellectual property, technology, and database assets around the world. Additionally, she is a leading authority on EU and US data privacy and information security laws. She has served on Lowenstein Sandler’s Board of Directors and Strategic Planning Committee, and chaired 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 (2009–2016) as a leading intellectual property attorney, Mary is described as "skilled, bright and knowledgeable," “top-notch” and is “recognized for her expertise in the field, with notable experience handling complex transactions involving significant IP assets.” Mary’s clients further commend her as “. . . 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 (2017) 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 the 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.
