Dispute Summary
Liberty Energy and Liberty Oilfield Services filed a detailed response defending the institution of IPR2025‑00139 against U.S. Well Services’ request for a Director’s discretionary denial. The brief leans heavily on Fintiv precedent and argues that the Board’s factual findings are correct and that the patent’s claims remain vulnerable to three prior‑art combinations.
