Kenneth E. Levitt



With a firm footing in both business counseling and patent litigation, Ken helps medical device and other technology companies identify, build, protect, and manage their valuable intellectual property assets.

Ken helps these businesses pursue sound strategies for IP litigation, particularly by developing technical strategies for patent litigation. He also counsels businesses on how to build successful strategies for their patent and trade secret portfolios, licensing, and product clearance, and helps them analyze validity and infringement concerns.

Ken understands the general counsel’s role well. He functioned in that capacity for a small cap medical device company for several years while a Dorsey partner, until the company was acquired by a Fortune 500 company.

Ken is a partner and Chair of Dorsey's Minneapolis Patent Group.
