Deanna Tanner Okun

Deanna Tanner Okun is a highly experienced international trade lawyer specializing in intellectual property disputes, particularly Section 337 investigations before the U.S. International Trade Commission (ITC). Her practice encompasses various aspects of unfair trade litigation and trade remedy advocacy, including allegations of patent, trademark, copyright infringement, and trade secret misappropriation. She advises clients across diverse industries, from Fortune 500 companies protecting leading-edge technologies to small and medium enterprises confronting foreign infringement.

Ms. Okun frequently represents both complainants and respondents in ITC proceedings. Her client work demonstrates a balanced approach, defending companies accused of infringement, such as Keysight Technologies in the tracked Centripetal Networks, Inc. v. Keysight Technologies, Inc. et al. patent-based action, Alarm.com in a patent-based Section 337 action which resulted in a finding of no violation, and Qualcomm in a patent-based ITC matter that settled favorably. Concurrently, she champions intellectual property owners, having represented LG Chem in a trade secret misappropriation case that led to a $1.8 billion settlement and NOCO in a patent and trademark action securing a Limited Exclusion Order.

Currently, Ms. Okun serves as the International Trade Commission Section 337 Litigation and Trade Remedies Chair at Polsinelli PC, a role she assumed in January 2023. Prior to joining Polsinelli, she was a Managing Partner at Adduci, Mastriani & Schaumberg LLP (AMS TRADE). A distinguishing aspect of her background is her significant public service as a U.S. ITC Commissioner for twelve years, including two terms as Chairman, where she presided over hundreds of intellectual property and trade remedy cases. While her expertise is heavily concentrated in ITC matters, the available information does not indicate a regular practice in PTAB or IPR proceedings.

Ms. Okun earned her J.D. with honors from Duke University School of Law and holds a B.A. with honors from Utah State University. She was admitted to legal practice in 1990 and is a member of the District of Columbia bar, also admitted to the U.S. Court of Appeals for the Federal Circuit.
