Loren L. Hansen

“The best part of my career is helping clients focus on their business while they are facing a legal dispute. It’s an honor to work with people who love what they do.”

Loren Hansen is a Registered Patent Attorney and first chair trial lawyer who focuses his practice on patent infringement, software / technology disputes, and intellectual property enforcement. He is also experienced in antitrust and other complex commercial litigation. Loren represents clients in a variety of industries, including agribusiness, manufacturing, construction, high technology, oilfield services, health insurance, and data storage.

Earlier in his career, Loren worked as a consultant with Accenture, Ltd., where he designed and developed custom software packages for large, national health insurers. His experience in software development, and education as a chemical engineer, continues to inform his practice – providing him with not only the insight needed to address the complex technical questions of many of his clients’ cases, but also the communication skills needed to untangle that complexity and convey it in understandable terms.

Loren's practice encompasses a variety of complex civil litigation. He represents his clients at trial (court and jury) and in arbitration proceedings throughout the country. Recognizing that many clients prefer pragmatic solutions to prolonged litigation, Loren works to provide solutions for his clients that help them minimize or avoid litigation whenever possible. Loren loves working with clients that have a genuine passion for what they do, and he strives to deliver advice that helps them grow.

Loren has served as co-chair of the litigation practice group and chair of the associate recruiting committee, where he advised on the hiring, retaining, reviewing, and professional development of associates. In addition, Loren served on the finance committee at the firm for three years.

Loren was born on a small-town family farm in southwest Minnesota and went to high school in West Fargo, North Dakota. The work ethic and values that he developed at an early age carry throughout his practice and his engagement with the community. In addition to being the past president of his church’s Council of Ministers, Loren serves as Secretary of the board, and sits on the governance and executive committees for the Minnesota Land Trust – a member-supported, nonprofit conservation organization whose mission is to protect and restore Minnesota's most vital natural lands in order to provide wildlife habitat, clean water, outdoor experiences, and scenic beauty for generations to come.
