Short Summary
Microsoft has filed a petition for inter‑partes review of Dialect’s ’367 patent covering natural‑language speech processing. The petitioner asserts that the claims are obvious over Belfiore, Kennewick, and Ross prior‑art references and seeks institution of the IPR.
Detailed Summary
In a petition for inter‑partes review (IPR2025‑01193), Microsoft Corporation challenges claims 11, 12, 15, 17, and 18 of U.S. Patent No. 7,917,367, which relate to synchronizing context across multiple devices in a natural‑language speech processing system. The petitioner contends that the claimed subject matter is obvious in view of three prior‑art references: Belfiore (EX1004), Kennewick (EX1005), and Ross (EX1007), each teaching similar device registration, event subscription, and context‑matching mechanisms. No objective evidence of non‑obviousness is presented, and Microsoft requests that the Board institute the IPR and find the challenged claims unpatentable.
