Google LLC v. Sonos, Inc.: All Five Patent Claims Fail After 1,635 Days
Google sued Sonos in the Northern District of California asserting five patents against the full Sonos smart speaker and audio streaming product line. After more than four and a half years, Sonos prevailed on every claim — through a combination of invalidity, subject-matter ineligibility, and summary judgment of non-infringement — with each party bearing its own attorneys’ fees.
Google’s five-patent offensive against Sonos ends in complete defeat
Google LLC filed this infringement action on 11 June 2020 in the U.S. District Court for the Northern District of California, asserting five patents — US7899187B2 (‘187), US7065206B2 (‘206), US8583489B2 (‘489), US10140375B2 (‘375), and US10229586B2 (‘586) — against the full range of Sonos smart speaker and audio streaming products, including the Sonos One, Five, Beam, Arc, Move, and the S1/S2 controller apps.
Each patent fell by a different legal route. The ‘489 patent was dismissed under Rule 12(b)(6) for subject-matter ineligibility under 35 U.S.C. § 101. The ‘206 patent was dismissed with prejudice at an early stage. The ‘375 and ‘586 patents had all asserted claims cancelled by the USPTO in inter partes review, with those cancellations affirmed by the Federal Circuit in May and June 2024 respectively. The ‘187 patent — the last remaining — was eliminated by two successive summary judgment rulings of non-infringement in May and October 2024, leading to a stipulated final judgment entered 2 December 2024.
The 1,635-day duration reflects the complexity of coordinating district-court litigation with parallel USPTO IPR proceedings that ultimately gutted two of Google’s five patents. The fee-neutral outcome — each party bearing its own costs — is consistent with neither side seeking or obtaining an exceptional-case finding under 35 U.S.C. § 285. The public record does not disclose any licensing agreement or commercial settlement, suggesting Sonos secured a clean litigated win rather than a negotiated resolution.

Sonos wins on all five patents: what the final judgment means for both parties
Five separate legal routes extinguished every Google claim
No single ruling ended this case — Sonos defeated each patent on its own terms. The ‘489 fell on § 101 subject-matter ineligibility. The ‘206 was dismissed with prejudice early. The ‘375 and ‘586 were cancelled at the USPTO and affirmed by the Federal Circuit. The ‘187 — the last to survive — was disposed of by two successive summary judgment rulings of non-infringement, with final judgment stipulated in December 2024.
Multi-pathway defenseGoogle exits with no injunction, no damages, and cancelled patents
Google’s outcome is materially adverse. Two patents (‘375 and ‘586) are permanently cancelled — they cannot be reasserted against anyone. The ‘489 patent is judicially declared subject-matter ineligible. The ‘187 and ‘206 are dismissed with prejudice, closing off future Sonos claims on those patents. Google bears its own legal fees after more than four years of litigation, consistent with no exceptional-case finding.
Complete plaintiff defeatSonos secures clean litigated win with no royalty obligation
Sonos prevailed on every asserted claim without paying any damages or royalties. Critically, Sonos’s defenses related to the ‘375 and ‘586 patents were dismissed without prejudice, preserving flexibility. The fee-neutral ruling means no cost shifting to Sonos. The outcome removes these five patents as enforcement tools against the current Sonos product line, providing meaningful commercial certainty for the smart speaker maker.
Full defense victoryCancelled patents cannot be wielded against the broader audio ecosystem
The cancellation of the ‘375 and ‘586 patents by the USPTO — affirmed by the Federal Circuit — has sector-wide effect. Any competitor previously exposed to those patents benefits from their permanent removal. The § 101 invalidity of the ‘489 patent similarly erases that enforcement vector. For smart speaker and audio streaming product teams, the outcome suggests that coordinated IPR filings alongside district-court litigation can be an effective total-defense strategy.

Official order — verbatim text
The stipulated final judgment reflects a structured disposition of five patents across four distinct legal mechanisms. The ‘187 non-infringement judgment is the only merits finding by the district court; the ‘375 and ‘586 dismissals with prejudice follow Federal Circuit-affirmed USPTO cancellations, making those dispositions res judicata. The ‘489 § 101 dismissal with prejudice is a judicial invalidity finding. The ‘206 dismissal with prejudice forecloses any future reassertion against Sonos. The fee-neutral order is notable given Sonos’s comprehensive win and warrants monitoring of any post-judgment cost proceedings.
US7899187B2 and four further patents — smart speaker audio streaming and control
The five asserted patents span core technologies in networked audio and smart speaker control. US7899187B2 covers encrypted and authenticated audio streaming to networked speakers — the claim set that ultimately survived longest in litigation. US8583489B2 relates to software-implemented audio playback control, which the court found patent-ineligible under § 101. US7065206B2 and the two ’10-series patents address distributed audio synchronisation, content routing, and playback coordination across wireless speaker groups.
Collectively, these patents represent a Google effort to assert foundational audio-networking IP against Sonos’s market-leading smart speaker ecosystem. The cancellation of the ‘375 and ‘586 patents by the USPTO narrows Google’s remaining enforcement arsenal in this technology space and signals that the PTO scrutinised and rejected the broadest claims in the portfolio. For competitors building multi-room audio, voice-assistant integration, or wireless speaker products, the survival and subsequent defeat of the ‘187 authentication claims is the most instructive data point.
Should you run an FTO against US7899187B2 and the Google audio streaming portfolio?
Any company developing wireless speaker systems, multi-room audio platforms, smart home controllers, or audio streaming applications should assess residual risk from Google’s audio-networking patent portfolio. While the ‘375, ‘586, and ‘489 patents have been cancelled or invalidated, and the ‘187 and ‘206 dismissed with prejudice as to Sonos, Google holds a broader patent estate in this space that may cover adjacent product architectures. Companies that were not parties to this litigation are not bound by these judgments.

What this case signals for the smart speaker and audio streaming IP landscape
A complete litigated defense win against a major technology plaintiff, achieved through parallel IPR and § 101 challenges, reshapes enforcement risk in the connected-audio sector.
Parallel IPR filings can be the decisive weapon in speaker-tech patent defense
Sonos’s success in cancelling the ‘375 and ‘586 patents via USPTO IPR — both affirmed by the Federal Circuit — eliminated two of Google’s five claims entirely, without needing to litigate them on the merits at trial. Companies facing multi-patent assertions in the audio and smart-home space should assess IPR viability as the primary defense track, not a secondary one.
§ 101 eligibility challenges remain a viable early-exit route for software-adjacent patents
Google’s ‘489 patent was dismissed at the pleading stage on subject-matter ineligibility grounds — one of the earliest and least costly dispositions available. The result reinforces that § 101 motions under Rule 12(b)(6) remain a strategically valuable first move against patents that claim abstract data-handling or signal-processing concepts in the audio streaming and smart-home domains.
Google v Sonos — key questions answered
Sonos prevailed on all five asserted patents. The ‘489 patent was dismissed for § 101 ineligibility, the ‘206 dismissed with prejudice, the ‘375 and ‘586 patents were cancelled by the USPTO and affirmed by the Federal Circuit, and the ‘187 patent was disposed of by summary judgment of non-infringement. Final judgment was entered 2 December 2024 with each party bearing its own attorneys’ fees.
Google accused the Sonos One, One SL, Five, Play:1, Play:3, Play:5, Playbar, Playbase, Beam, Arc, Move, Connect:Amp, Amp, Connect, Sub, and the Sonos S1 Controller App and S2 App of infringing its five asserted patents covering audio streaming, encryption, and smart speaker control technology.
All asserted claims of both patents were cancelled by the U.S. Patent and Trademark Office through inter partes review proceedings. The PTO’s cancellation judgments were affirmed by the Federal Circuit — the ‘586 in May 2024 and the ‘375 in June 2024. Google’s district court infringement claims for these patents were subsequently dismissed with prejudice, as no valid claims remained to enforce.
The ‘489 patent was dismissed under Rule 12(b)(6) — at the pleading stage — on the grounds that it is subject-matter ineligible under 35 U.S.C. § 101. The court found the patent covered patent-ineligible subject matter, resulting in a dismissal with prejudice. This was one of the earliest dispositions in the case and did not require claim construction or merits discovery.
No. Google received no damages award, no injunction, and no royalty payment. The final judgment specified that each party shall bear its own attorneys’ fees, which is consistent with neither party obtaining an exceptional-case finding under 35 U.S.C. § 285. Taxable costs were to be addressed by separate order, but the public record does not indicate any monetary recovery by Google.
