Short Summary
Elong International and Xiamen Longstar have filed an IPR petition seeking cancellation of 16 claims of Feit Electric’s white‑light LED patent, arguing the claims are obvious over several LED‑lighting references. The petition cites Basin‑2007, Krummacher, Hussell and others as prior art.
Detailed Summary
In Petition IPR2025‑00258, Elong International USA Inc. and Xiamen Longstar Lighting Co. Ltd. request inter‑ partes review of U.S. Patent No. 8,604,678, owned by Feit Electric Company, Inc. The petition challenges claims 1‑3, 6‑7, 9‑10, 16‑21, 25‑26 and 29, asserting that each is obvious under 35 U.S.C. § 103 in view of prior‑art references such as Basin‑2007 (combined with Basin‑2005), Krummacher (combined with Shimizu and Stokes), and Hussell (combined with Van Woudenberg). The petition argues that the examiner was not aware of these teachings, that there is no evidence of non‑obviousness, and that the claims should be cancelled. No institution decision has been made yet; the proceeding remains at the petition stage.
