Boston Dynamics sues rival Ghost Robotics for allegedly copying its robot dog

Competition in the robot dog market is getting ugly. As The Robot Report explains, Boston Dynamics is suing Ghost Robotics for allegedly infringing seven patents linked to its Spot quadruped. The Spirit 40 and Vision 60 (shown above) purportedly borrow key technologies from Spot, including systems for self-righting and climbing stairs. Boston Dynamics says it asked Ghost Robotics to review Spot-related patents in July 2020, five months after the launch of the Spirit 40. After that, Boston claims to have sent two cease-and-desist letters asking Ghost to stop marketing its robot canines.
