US marshals have raided a Chinese company’s booth at Las Vegas tech show CES – seizing all of the hoverboard-maker’s one-wheeled vehicles.
Onlookers said people working on the Changzhou First International Trade Co stall were stunned.
A team of marshals were seen confiscating products and merchandising material, which the US Department of Justice say is related to a civil case.
It follows a patent infringement claim filed by a Silicon Valley-based rival, and the case is set to reach court in the next few days.
The firm’s hoverboard model – featuring a single central wheel rather than one at each end – is similar to California-based Future Motion’s Onewheel vehicle.
The Onewheel uses sensors and computer controls to balance the board, which are covered by two key patents stopping rivals using similar technology for free.
