South Korean auto parts maker Mando Corp. challenged German rival Robert Bosch GmbH with a countersuit in a U.S. court, claiming that it was the German company that had infringed on two of its patents on braking components and not the other way around, according to multiple industry sources Friday.
In a suit filed with a U.S. district court for the Eastern District of Michigan, Mando defended itself in the charge that it had violated four of Bosch-owned patents in brake control systems.
Mando submitted a response Monday to the U.S. court firmly denying Bosch’s claims and instead insisting that the German auto parts supplier infringed its two patents on an electronic brake control system and a solenoid valve for a brake system.
The Korean car parts supplier claimed Bosch had been aware of the patents from Dec. 2 but kept on with manufacturing and sales. It accused Bosch had been using its patented technology in Antilock Brake Systems (ABS) and Electronic Stability Control (ESC) parts. ABS is an automobile safety system that helps drivers from avoiding crashes by reducing the danger of skidding while braking, preventing the wheels from locking up. ESC is a computer controlled technology that prevents a car from unwanted skidding or losing control from over-steering.
Mando requested the U.S. court to prohibit Bosch from further infringing its patents without specifying the damage value.
