The patent-in-suit is U.S. Patent No. 8,941,363 (the ‘363 patent). Titled “Device Battery Management,” the patented invention “comprises a system and method for providing battery management for a device.” Sony’s Xperia XZ3 is accused of infringing upon the ‘363 patent by “determining a device battery top-off charge trigger associated with the device” and its battery. This means that the mobile phone learns a user’s charging habits and approximates when the device will be disconnected from its charger.
According to a chart in the complaint, keeping a mobile device perpetually charged to 100% can damage its battery, so it is optimal to keep the charge at 90% over longer periods of time (like when a user is asleep). The Xperia XZ3 phone learns a user’s charging habits to determine when to keep the battery level at 90% and when to provide a full charge. Syclone accused Sony’s phone of including “a machine readable non-transitory medium having stored therein instructions that, when executed, cause the machine to provide battery management for the device.”
As a result of Sony’s alleged patent infringement, Syclone seeks an award of compensatory damages and an order permanently enjoining the company from further violations.
