Detailed Summary

In IPR2025‑00385, Zhuhai CosMX Battery Co., Ltd. sought Director Review of the PTAB’s earlier decision to deny institution of an inter partes review of Ningde Amperex Technology Limited’s battery‑related patent (U.S. Patent No. 10,964,927 B2). After considering the petition and the patent owner’s authorized response, the Office, under Director John A. Squires, concluded that the petition failed to meet the statutory criteria for review and therefore ordered the request denied. The denial upholds the original institution decision, meaning the IPR will not proceed.
