Sonos Company has accused Google of patent infringement for the second time this year. The first claim was filed early this year.
In a new lawsuit to the original list of violations in “some audio players and controllers, components and products containing them” Google added five more patents. They cover technologies that serve as the basis for some of Sonos’ most famous functions, in particular, Trueplay, a tool to improve sound by calibrating the speaker to the acoustic characteristics of the room.
The source recalls that the first lawsuit also includes five patents related to Sonos speakers. One of these patents is for technology that allows wireless speakers to synchronize with each other.
In June, Google filed a countersuit claiming that Sonos, without a license, used Google’s search, software, networking and sound processing technologies.
