Two Chinese companies have been found to have violated patent infringement and deceptive trade laws by a US court.

Ride manufacturer Zamperla brought two separate lawsuits – against Beijing Shibaolai Amusement Equipment and Zhongshan Golden Dragon Amusement Equipment Company – which said the Chinese companies wrongfully engaged in unfair competition and patent infringement in violation of Federal law, and deceptive trade practices under Florida law.

Ruling in Zamperla’s favour, a Florida court issued permanent injunctions against the Chinese companies forbidding them from “selling or attempting to sell counterfeits, copies, or confusingly similar rides” to a number of those designed and manufactured by Zamperla.

“We will not and cannot tolerate other companies infringing on our works,” said Alberto Zamperla, head of Antonio Zamperla SpA. “We will continue to protect our company and the public from rides which appear to be Zamperla equipment, but which were not engineered or manufactured to our standards.”

The lawsuits were brought by Antonio Zamperla SpA of Italy and Zamperla Inc. of the US, with the injunction applying to the company’s Disk’O, Sky Drop, Jump Around, Flying Carousel, Flying Tigers, Moto Coaster, and Rockin’ Tug amusement rides.
