Short Summary
Samsung has filed an IPR petition seeking cancellation of all 20 claims of Network‑1’s eUICC security patent, alleging obviousness over a combination of prior‑art references covering secure profile provisioning and IMSI encryption.
Detailed Summary
In a petition for inter‑partes review, Samsung Electronics and its U.S. affiliate request that the Patent Trial and Appeal Board institute a review of claims 1‑20 of U.S. Patent No. 12,166,869, which covers methods for eUICC provisioning, key derivation, and authentication in mobile devices. Samsung contends that each claim is obvious in view of a predictable combination of prior‑art references—including Nakhjiri’s secure profile delivery, Bradley’s IMSI and key handling, Jeong’s privacy‑preserving authentication, Ala‑Laurila’s Diffie‑Hellman‑based IMSI encryption, the ANSI X9.63 key‑derivation standard, Pierce’s entropy‑based key generation, and GlobalPlatform’s TLV connection parameters. The petition lists seven grounds of obviousness, each targeting specific claim groups, and asks for cancellation of all claims. No claim constructions or expert testimonies beyond Dr. Sundeep Rangan are presented, and the proceeding is currently awaiting a decision on institution.
