BlackBerry maker Research in Motion (RIM) has been temporarily banned from using Basis International's BBX trademark.
Basis International obtained a temporary restraining order from a U.S. federal court in Albuquerque, which bars RIM from using the BBX trademark at its Asian DevCon conference this week in Singapore.
RIM has appeared to backtrack on using the trademark.
"RIM doesn't typically comment on pending litigation, however RIM has already unveiled a new brand name for its next generation mobile platform," RIM said in a statement.
"As announced at DevCon Asia, RIM plans to use the 'BlackBerry 10' brand name for its next generation mobile platform."
BBX, the operating system that Research In Motion is counting on to revive its BlackBerry franchise, has run into trouble even before the company could install the system in its smartphone line.
Albuquerque-based Basis International claims the "BBX" name is protected by trademarks it holds and had earlier threatened to take legal action against RIM unless it stopped using the moniker.
Basis said RIM had refused requests to stop using the moniker at the DevCon conference, which resulted in the company filing for the temporary restraining order.
