The plaintiff claimed that the several models of Sonos's smart speakers allow this functionality via Google Assistant, these can also be used to control other connected smart devices. In this circumstance, the Sonos speaker would be the first device and the other smart device, such as a smart TV or smart oven would be the second device. The plaintiff also claimed that the Sonos app can control music played on the Sonos smart speaker. In particular, Cedar Lane Technologies asserted that, as described in the patent, the Sonos App on a Google Assistant device is the first device that "(a) obtains auditory information from external to the first device where the information comprises a human-understandable device command directed toward an operation of the second device, (b) manipulates the obtained information, and (c) transmits the manipulated information to a distal computer system."
