Dispute Summary
Zhuhai CosMX Battery has filed a corrected IPR petition seeking cancellation of 21 claims of Ningde Amperex’s 2023 lithium‑ion battery electrolyte patent. The petition relies on multiple foreign and U.S. references that allegedly disclose the same dinitrile, trinitrile and propyl propionate compositions. The petitioner argues that the claims are obvious under 35 U.S.C. § 103.
