Dispute Summary
Liberty Energy has filed an IPR petition seeking cancellation of 20 claims of U.S. Patent 11,459,863 covering electric‑powered multi‑plunger fracturing pump systems. The petition relies on multiple prior‑art references, chiefly Fischer, to argue obviousness under 35 U.S.C. §103 and argues that discretionary denial is unwarranted.
