Mary is experienced in various facets of intellectual property law, including patent and trademark litigation, as well as patent prosecution.

Prior to attending law school, she earned her bachelor’s degree in Computer Science Engineering from Michigan State University, with a minor in business. During her studies, Mary worked with Motorola, Inc. to develop innovative mobile technology for integration with cable television and video-on-demand services.

In 2013, she received her J.D. from DePaul University College of Law.
