Fred Hutchinson Cancer Research Center defeats IPR petition brought by Miltenyi Biomedicine GmbH

Client(s) Fred Hutchinson Cancer Research Center

Jones Day represented patent owner Fred Hutchinson Cancer Research Center, on behalf of exclusive licensee Bristol Myers Squibb, in successfully defeating a patent challenge in an inter partes review (IPR) proceeding brought by petitioners Miltenyi Biomedicine GmbH and Miltenyi Biotec Inc. ("Miltenyi") in the U.S. Patent and Trademark Office Patent Trial and Appeal Board (PTAB). The proceeding involved U.S. Patent No. 9,987,308 related to an adoptive cellular immunotherapy composition. The PTAB ruled in favor of the patent owner by denying institution in September 2023, thereby avoiding a full trial. Miltenyi filed a request for rehearing, which the PTAB denied in February 2024.
