Pratt & Whitney has hit back at Rolls-Royce patent suit against it, filing a lawsuit against the UK-based engine manufacturer. The US company, a unit of United Technologies Corp, has filed a suit in a US Federal Court in Connecticut claiming that Rolls-Royce has misled the US Patent and Trademark Office to obtain a patent and then unlawfully used that patent to enter litigation against Pratt & Whitney, interfering with its business and engaging in unfair business practices.
