Detailed Summary

In this petition for inter partes review, Google LLC challenges U.S. Patent No. 11,080,001 owned by Sonos, Inc., which claims methods for synchronizing audio playback among multiple zone players. Google asserts that claims 1‑3, 6‑14, 17‑25, and 28‑33 are unpatentable as obvious over the combined teachings of Janevski, Kawamura, Okamura, and Kono. The petition details how each claim limitation is disclosed in the prior art, provides claim constructions agreed upon by the parties, and argues that discretionary denial under 35 U.S.C. §§ 314(a) and 325(d) would be inappropriate. Google requests that the PTAB institute the IPR and cancel the challenged claims.
