A US judge throws out a $32.5M jury verdict for Sonos in its smart speaker patent case against Google after finding that the Sonos patents were unenforceable

Context & Ripple Effects
The dispute had already been narrowed before trial: a federal judge invalidated two of four asserted Sonos patents while allowing the remaining claims to proceed in the May trial against Google. A California jury then found infringement of a Sonos patent and awarded $32.5 million to Sonos.
The new ruling removes that jury result because the patents at issue were found unenforceable, shifting the case from a damages question to whether Sonos can rely on those patents at all.
First-order effects
- Sonos loses the $32.5 million jury award, while Google no longer faces liability under the vacated verdict.
- The unenforceability finding undercuts Sonos' ability to enforce the patents involved in this case against Google.
Second-order effects
- Google gains leverage in the parties' patent dispute, while Sonos must rely on any claims and patents that remain viable after the court's earlier narrowing of the case.
- The outcome shows that a favorable infringement verdict can still be undone by a later ruling on patent enforceability, raising the importance of validity and enforceability defenses alongside trial damages arguments.
Third-order effects
- If courts continue to closely test asserted patents after jury trials, smart-device companies may place less value on single-case damages wins and more on portfolios that can survive multiple legal challenges.
- The case illustrates a broader shift in technology-patent litigation: verdicts are not necessarily final leverage when threshold patent defenses remain available.
The trend: Technology patent disputes are increasingly decided not only by infringement findings, but by whether the underlying patents remain enforceable through post-verdict review.
