Cedar Lane Technologies Inc. has filed a lawsuit in the District of Delaware against Sonos Inc. for allegedly infringing the patent-in-suit via its smart speakers and app that utilize voice commands.

The plaintiff alleges that the defendant infringed on its patent-in-suit with United States Patent No. 8,165,867 (the ’867 patent) covering methods for translating a device command.

According to the lawsuit, the plaintiff reportedly said that the defendant’s smart speakers with Sonos app and Google Assistant infringe at least claim 1 of the ’867 patent which uses a method where a first electronic device is used to operate a second electronic device in real-time, while the second device is not physically connected to the first device, and is only intermittently local to the first device.

The plaintiff alleges that several models of Sonos’s smart speakers allow this functionality via Google Assistant, these can also be used to control other connected smart devices which infringe the ’867 patent.

The plaintiff reportedly said that the Sonos App on a Google Assistant device is the first device that 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, manipulates the obtained information, and transmits the manipulated information to a distal computer system.

The plaintiff is accusing the defendant of direct and induced infringement, as well as knowingly and willfully infringing the patent-in-suit.

The plaintiff is seeking a declaratory judgment in its favor; an award for damages, costs, and fees; and other relief.

The case is ongoing.
