MUMBAI, Oct. 11 -- The Bombay High Court has temporarily restrained two taxi operators in Delhi and Dehradun from using the brand name JioCabs or any other name similar to JIO, a trademark owned by Reliance Industries Limited (RIL). In an interim order passed on October 7, the court observed that the Mumbai-headquartered conglomerate has made out a strong, prima facie case of trademark and copyright infringement against the taxi operators.
