Dispute Summary
Liberty Energy petitions the PTAB to institute an IPR against U.S. Well Services' 11,959,533 patent covering multi‑plunger hydraulic fracturing pumps. The petition asserts that all 25 claims are obvious under §103, relying on a series of prior‑art combinations and argues that institution is proper under the Fintiv and Becton factors.
