Federal Circuit rules in favor of Finnegan clients Hyundai and Kia in a tire pressure monitoring system patent case

In a unanimous opinion, the U.S. Court of Appeals for the Federal Circuit ruled that MHL Tek LLC did not own three Tire Pressure Monitoring System patents, resulting in a victory for Finnegan clients Hyundai Motor Company and Kia Motors Company and other automobile maker co-defendants.  Specifically, the Federal Circuit (1) affirmed the Eastern District of Texas court’s holding that MHL Tek lacks standing to assert two of the three patents-in-suit, and (2) reversed the court’s holding that MHL Tek has standing to assert the third patent-in-suit.
