Microsoft Corporation v.Dialect, LLC
Microsoft has filed an IPR petition seeking to invalidate claims 1‑3 and 6 of Dialect’s ‘409 patent on dynamic speech sharpening. The challenger relies on the Bazzi paper and the Sabourin and Epstein patents to argue obviousness under 35 U.S.C. § 103.
Amazon.com, Inc. et al. v.KAIFI LLC
Amazon has filed an IPR petition seeking to invalidate KAIFI’s U.S. 8,930,196 patent covering a two‑step voice‑activation system. The petition argues that all 20 claims are obvious over Bou‑Ghazale combined with token‑passing, phoneme/anti‑phoneme models, and adaptive filtering. It also contends that discretionary denial under §314(a) and §325(d) is unwarranted.
Samsung Electronics Co., Ltd. et al. v.Cerence Operating Company
Samsung’s request for Director Review of the PTAB’s denial of institution for its IPR against Cerence’s voice‑control patent was rejected. The Board affirmed that all Fintiv factors favored discretionary denial, rendering the review request untenable.
Google LLC v.Dialect LLC
Google LLC successfully initiated an IPR challenge against Dialect LLC's patent (9031845) covering natural language speech processing in vehicles. The Board found a reasonable likelihood of prevailing, focusing on obviousness under 35 U.S.C. § 103 using prior art references like Coffman, Julia, and Cooper.
