Following the US ITC's ruling in favor of Sonos, Google changes Assistant device setup and Speaker Groups, which now require adjusting speakers individually
Following the US ITC ruling in favor of Sonos, Google this afternoon announced a series of changes to how Speaker Groups and its Assistant devices work.
Context & Ripple Effects
Google and Sonos had a long-running Assistant relationship before the dispute: Sonos delayed its planned integration before bringing Google Assistant to Sonos One and Beam in 2019. The ITC’s finding that Google infringed five Sonos audio patents turned that interoperability history into a product-design constraint.
The constraint was not permanent: after a judge invalidated the relevant patents, Google restored support for multiple Speaker Groups in 2023. That reversal makes the 2022 changes a clear example of software capabilities tracking the status of underlying IP rights.
First-order effects
- Google Assistant and Speaker Groups users lose group-level adjustment workflows, with speakers requiring individual changes.
- Sonos gains an ITC-backed infringement finding against Google, while Google must alter affected device setup and multi-speaker behavior.
Second-order effects
- Google’s hardware and Assistant teams must treat multi-device audio controls as a legal-design issue rather than a purely usability-driven feature.
- The ruling gives Sonos stronger leverage in a connected-audio market where Google’s service integration had been part of Sonos’s product roadmap.
Third-order effects
- The later restoration of multiple Speaker Groups shows that patent validity can make connected-device features reversible, requiring platforms to maintain workarounds and re-enable capabilities as litigation changes.
- If this pattern persists, interoperability in smart-home audio will be shaped not only by platform compatibility but also by which interface and synchronization techniques remain enforceable.
The trend: Smart-home platforms are increasingly designing and withdrawing interoperability features in response to patent enforcement, then restoring them when legal constraints lift.
