Dispute Summary
Google has filed a petition for Director Review seeking to overturn the PTAB’s denial to institute an IPR against Dialect’s voice‑command patent. The petition contends the Board misapplied the Coffman reference and ignored unrebutted expert testimony, arguing that the disputed claim steps are obvious. Google requests that the decision be vacated and the IPR be instituted.
