Hana Oh


Hana Oh, Ph.D., is an MIT-trained attorney in O’Melveny’s Intellectual Property and Technology practice group. Hana focuses on patent and trade secret litigation and licensing issues for innovative companies, ranging from small businesses and startups to large companies such as Samsung, Micron, Belkin, Alcon, and Novartis. Hana is registered to practice before the US Patent and Trademark Office. Clients entrust her to navigate complex scientific and technical issues arising in intellectual property disputes. Hana has also skillfully managed teams, experts, and co-counsel through many phases of litigation, from pre-filing investigation, pleadings, complex discovery, and motion practice to settlement negotiations and pre-trial filings. She is fluent in Korean, and serves as an effective advisor to Korean clients regarding litigation in the U.S. and licensing issues. As a former researcher and engineer, Hana understands the importance of protecting a company’s valuable IP assets. Before working as an attorney, Hana designed microfluidic devices to study cellular mechanics, using both mathematical modeling and experimental approaches. She conducted postdoctoral research at a leading biotechnology company. She also prosecuted patents and developed portfolios in a wide range of technology industries. Her research and prosecution experience enables her to bring a critical and deep-probing approach to all litigation matters. Hana’s tireless advocacy extends to her active pro bono practice, particularly in advocating for domestic violence victims. For example, she argued for and obtained asylum in the U.S. on behalf of three siblings from Guatemala, who were victims of domestic abuse. She also successfully obtained a U Visa for a sexual abuse victim and his family. Hana is active in the legal and tech communities. She has served on the board of the Markey Intellectual Property Inn of Court, OCKABA (Orange County Korean-American Bar Association), and the Planning Committee for Human Options (nonprofit serving victims of domestic abuse). An effective speaker who is particularly adept at discussing various IP issues tailored to attorneys and scientists, she has spoken at national conferences and PLI (Practicing Law Institute).
