Google v. Sonos (337-TA-1329): ITC finds no violation after 973-day investigation
Google filed an ITC Section 337 complaint against Sonos in August 2022, asserting three patents covering hotword detection across multiple devices and wireless charging technology. After nearly three years of proceedings before ALJ McNamara, the Commission found no violation — a full merits win for Sonos.
Google’s ITC counterattack against Sonos ends in complete defendant victory
Google LLC filed ITC Investigation No. 337-TA-1329 on 9 August 2022, asserting that Sonos, Inc. imported and sold products that infringed three US patents: US10593330B2 (hotword detection on multiple devices), US10134398B2 (a related hotword detection method), and US7705565B2 (wireless charging systems). The complaint targeted Sonos smart speakers and related audio products — devices at the commercial heart of the ongoing rivalry between the two companies. The case was presided over by Administrative Law Judge MaryJoan McNamara.
After 973 days of proceedings — nearly three years — ALJ McNamara issued a finding of no violation on the merits. The basis of termination is recorded as a judgment on the merits for the defendant, meaning the Commission did not find that Sonos infringed any of the three asserted patents to the degree required to constitute a Section 337 violation. No exclusion order or cease-and-desist order issued against Sonos. This outcome represents a full substantive win for Sonos, not a procedural dismissal or settlement.
The 973-day duration substantially exceeds the ITC’s stated 15–18 month target timeline, suggesting protracted claim construction disputes, technical complexity across two distinct technology areas, or extensive discovery and expert proceedings. The public record does not disclose the specific grounds — non-infringement, invalidity, or both — on which the finding rested. The result is notable context given the broader Google-Sonos patent dispute history, in which Sonos had previously filed its own ITC and district court actions against Google.

ITC finds no violation: what the merits ruling means for both parties
A Section 337 merits finding — not a dismissal or settlement
At the ITC, a ‘no violation’ finding on the merits means the Administrative Law Judge determined that the complainant failed to establish the elements of a Section 337 violation — typically requiring importation, infringement of a valid and enforceable patent, and a domestic industry. This is the most complete form of defendant victory available at the Commission, and is distinct from a consent order, settlement, or procedural termination.
Full merits adjudicationGoogle’s ITC route closed — no exclusion order, no cease-and-desist
The no-violation finding means Google obtained no exclusion order barring Sonos imports and no cease-and-desist order restricting domestic sales. Google retains the asserted patents and could pursue parallel district court infringement actions, but the ITC’s fast-track remedy — import exclusion — is foreclosed for this investigation. A finding on the merits also creates a factual record that may affect any co-pending district court proceedings.
No ITC remedy issuedSonos clears all three patent claims at the ITC
Sonos prevailed on the merits against all three asserted patents — covering both hotword detection and wireless charging technology. This finding protects Sonos’s current product import stream from ITC-based exclusion. The public record does not specify whether the ruling was grounded in non-infringement, invalidity, or failure to establish a domestic industry, but the breadth of the win across multiple patents and technology areas is commercially significant.
Full defendant victorySonos supply chain secured; Google-Sonos patent rivalry continues
Sonos can continue importing and selling its smart speaker lineup without ITC-imposed restrictions following this ruling. However, the broader Google-Sonos IP dispute involves multiple proceedings across multiple venues, and this ITC result does not necessarily resolve parallel district court exposure. For the smart speaker and voice-AI sector, the ruling suggests that hotword detection and wireless charging patent claims of this scope face meaningful validity or infringement hurdles at the Commission.

Official order — verbatim text
The verdict — ‘No Violation Found’ on a basis of judgment on the merits for the defendant — is the most complete outcome Sonos could have achieved at the ITC. It forecloses the specific remedies Google sought (import exclusion and cease-and-desist) for the patents at issue. Because this is a first-instance ITC determination, the Commission may review ALJ McNamara’s findings, and either party may seek review before the Federal Circuit thereafter. The merits basis of the ruling distinguishes it from a procedural termination and may carry persuasive weight in any co-pending district court proceedings involving the same patent claims.
US10593330, US10134398 & US7705565 — hotword detection and wireless charging
The three asserted patents span two distinct technology domains. US10593330B2 and US10134398B2 relate to hotword detection — specifically, coordinating which device in a multi-device environment responds to a voice trigger such as ‘Hey Google’. These patents address the suppression and coordination logic that prevents multiple smart speakers from simultaneously activating. US7705565B2 covers wireless charging systems, relevant to Sonos products with wireless power capabilities. All three patents are granted US utility patents assigned to Google.
The hotword detection patents are strategically significant because they address a core functional layer of modern voice-assistant ecosystems — the competition between Google Assistant and Sonos’s integrated assistant features. Asserting these patents at the ITC reflects Google’s effort to use its foundational AI-interface IP as a competitive weapon. The inclusion of a wireless charging patent alongside voice-AI patents suggests Google identified a broad range of technical touchpoints in Sonos hardware. The no-violation finding across all three patents limits the immediate enforcement value of this portfolio against Sonos, though the patents remain in force.
Should you run an FTO against US10593330, US10134398, and US7705565?
Any company developing multi-device voice assistant products, smart speaker hardware, or wireless charging–enabled audio devices should assess freedom-to-operate against this patent family. The ITC’s no-violation finding protects Sonos specifically in this investigation but does not dedicate these patents to the public or formally limit their scope against other parties. Hardware and software teams building hotword arbitration logic or wireless charging receivers in consumer electronics remain exposed.

ITC no-violation rulings create durable factual records for parallel litigation
A merits-based no-violation finding at the ITC, unlike a settlement or consent order, generates a substantive record on claim construction, infringement, and potentially validity. Parties in co-pending district court actions involving the same patents should assess whether ALJ McNamara’s findings carry preclusive or persuasive weight in those forums.
Hotword detection patents face growing scrutiny at the Commission
Google’s failure to establish a Section 337 violation on hotword-detection claims (US10593330 and US10134398) suggests that these patent claims face meaningful challenges around infringement scope or domestic industry requirements. Companies building voice-assistant features should monitor the claim construction positions adopted in this record.
Google v Sonos — key questions answered
ALJ MaryJoan McNamara issued a no-violation finding on the merits in favor of Sonos, Inc. The basis of termination is judgment on the merits for the defendant. No exclusion order or cease-and-desist order issued. The investigation closed on 8 April 2025 after 973 days.
Google asserted three US patents: US10593330B2 and US10134398B2, both directed to hotword detection coordination across multiple devices, and US7705565B2, covering wireless charging systems. The products at issue included Sonos smart speakers and wireless charging–enabled audio hardware.
A no-violation finding on the merits means the ITC determined Google failed to establish a Section 337 violation — requiring infringement of a valid patent and a qualifying domestic industry. Sonos faces no import exclusion order from this investigation. The ruling is a full merits win, not a settlement or procedural dismissal.
Yes. ITC ALJ initial determinations are subject to review by the full Commission. Following any Commission review, either party may appeal to the US Court of Appeals for the Federal Circuit. The public record does not indicate whether Google has filed or intends to file a petition for review as of the case close date.
This no-violation finding closes Google’s ITC enforcement route for the three asserted patents but does not resolve any parallel district court actions involving the same or related patents. The Google-Sonos dispute has involved multiple ITC and district court proceedings initiated by both parties. IP strategists should monitor co-pending actions for ongoing exposure in either direction.
