Short Summary
RØDE Microphones and Freedman Electronics have filed an IPR petition seeking cancellation of 11 claims of Zaxcom’s ’207 patent, arguing obviousness over four prior‑art references and invoking collateral estoppel from earlier PTAB decisions.
Detailed Summary
In Petition IPR2025‑00232, RØDE Microphones, LLC and Freedman Electronics Pty Ltd request inter‑partes review of U.S. Patent No. 10,276,207, challenging claims 17‑19, 21‑23, 33, 34, 59, 60, and 66. The petition asserts that the claimed wearable audio‑recording system is obvious in view of the Strub, Woo, Nagai, and Gleissner references, and that Zaxcom is estopped from contesting the PTAB’s earlier findings in the Lectrosonics IPRs. It further argues that the examiner never meaningfully considered these references, supporting institution, and contends that discretionary denial under §§325(d) and 314(a) is unwarranted. The petition is pending before the PTAB.
