Sonos gains after winning US import ban on some Google devices

Sonos Inc rose in post-market trading after it won a US trade agency ruling that will limit the imports of some phones, laptops and speakers made overseas by Alphabet Inc’s Google because they infringe patents for home audio technology.

The US International Trade Commission issued the ban Thursday after affirming a judge’s findings that the devices were using Sonos’ patented inventions without permission. The Biden administration can veto the exclusion order on public-policy grounds, though that rarely happens. Otherwise, the ban takes effect in 60 days.
