Google Infringed on Speaker Technology Owned by Sonos, Trade Court Rules

Sonos seems to patented the concept of "paired" speakers itself, and the protocol used to synchronize speaker's clocks for synchronous playback.

I wonder how Bose manages to produce their own multiroom system. Do they license the patents or do they somehow work around them?
