American Vehicular Sciences, a subsidiary of Acacia Research, filed four separate suits against Kia Motors asserting a number of patents related to vehicular components. The first suit asserts five patents generally related to vehicle monitoring and diagnostic systems (6,738,697, 7,082,359, 7,650,210, 8,019,501, and 8,036,788) and accuses Kia’s automatic crash notification, vehicular diagnostic, and other similar systems of infringing the patents. The second suit asserts a single patent related to weight measuring (7,413,048) targeting the defendant’s occupant classification system. The third suit, which also asserts a single patent, claims that Kia’s crash detection systems – that employ methods for removing a headrest based on crash detection – infringes a patent related to rear impact detection methods (8,346,438). The final suit, which asserts three additional patents related to vehicle control, occupant protection, and vehicle diagnostic systems (8,060,282, 8,157,047, 8,229,624), alleges infringement through similar vehicular components utilized by Kia. Since June 2012, American Vehicular Sciences has filed 15 prior suits, including three against Hyundai, five against BMV, and seven against Toyota. The patents-in-suit originated with Automotive Technologies International (ATI) and were assigned to American Vehicular Sciences in April 2012. 2/13, Eastern District of Texas, 6:13cv00150; 6:13cv00149; 6:13cv00148, 6:13cv00147.
