Short Summary
Murata has filed an IPR petition seeking to invalidate claims 1‑2 and 4‑20 of U.S. Patent 7,489,914 on the basis of obviousness over prior art references Yeh, Dalmia, and Hashemi. The petition argues no discretionary denial factors apply and requests institution of the trial.
Detailed Summary
In IPR2025-00384, Murata Manufacturing Co., Ltd. challenges claims 1‑2 and 4‑20 of U.S. Patent 7,489,914, which covers a multi‑band RF device with embedded passive components on an organic substrate. The petitioner relies on two statutory grounds of obviousness under 35 U.S.C. §103(a): (1) the combination of Yeh (U.S. Patent 5,995,814) and Dalmia’s dissertation, and (2) the combination of Dalmia and Hashemi’s IEEE article. Both grounds are argued to render the challenged claims unpatentable, and the petition contends there is no basis for a discretionary denial under §§325(d) or 314. The filing seeks institution of the IPR to cancel the claims, aiming to resolve parallel district‑court litigation.
