TORONTO (AP) — BlackBerry-maker Research In Motion has been forced to change the name of its new operating system from BBX after the company lost a trademark ruling.

The name change is the latest in a string of bad news for the Canadian company.

RIM said in a statement Wednesday that "BlackBerry 10" will be the new brand name for its next generation mobile platform. Analysts say RIM's future depends on a successful launch of the new platform which RIM dubbed BBX just months ago.

A U.S. federal court judge in Albuquerque, New Mexico, banned RIM from using the BBX name at a conference being held in Singapore this week after finding that software company Basis International Ltd. had registered and used the trademark for 26 years.
