Dispute Summary
Microsoft has filed an IPR petition challenging eight claims of Dialect’s 8,195,468 patent covering multimodal voice‑assistant technology, asserting obviousness over the Maes, Coffman, and Ittycheriah references. The petition argues the examiner never considered these references, creating a material error, and urges the Board to institute review.
