Ellisen Turner is a partner in the Intellectual Property Practice Group of Kirkland & Ellis LLP. Based in the Los Angeles office, his broad IP practice includes patent and trade secret litigation and intellectual property transactions. Ellisen is an IP strategist who combines business acumen with deep understanding of IP law to support his clients’ business goals and maximize the value of their technology.

Ellisen represents and counsels clients in complex commercial and intellectual property disputes in federal courts, as well as in the U.S. International Trade Commission (ITC), the Patent Trial and Appeal Board (PTAB) and domestic and international arbitrations.

Ellisen helps clients develop strategies to successfully monetize their technologies, maximizing the value of both tangible and intellectual assets. He counsels businesses on technology development and commercialization and represents them in bankruptcy matters and transactions.

Clients rely on Ellisen both for his track record of success and for the enormous creativity he brings to each matter. Through his holistic approach, he takes the time to understand his clients’ business plans, short-term objectives, and long-term definitions of success. Armed with this knowledge, he crafts successful, often groundbreaking, legal strategies that meet clients’ critical business goals and pave the way to success in future endeavors.

Frequently invited as a speaker on patent law, Ellisen has presented on patent litigation and patent damages at the American Intellectual Property Law Association (AIPLA) and other intellectual property conferences. He has been an associate columnist for the National Law Journal and has co-authored several papers and presentations regarding patent law and practice topics, including forum selection in patent infringement litigation, claim construction hearing practice and pre-litigation investigations.
