The new owner of Saab said it is looking for a solution "as soon as possible" to the current block on its right to use of the Saab name and badge.
National Electric Vehicle Sweden (NEVS), a Chinese Japanese investment group, bought the Swedish automaker from administrators earlier this month after Saab was forced into bankruptcy late last year though financial problems.
The sale did not include permission to use the Saab name and logo. This can only be granted by defense company Saab AB and truck maker Scania, both of which use the same griffin logo seen on Saab passenger cars.
Scania said the agreement went back to 1990 when General Motors Co. bought 50 percent of the passenger-car division of the single company that included Saab AB, Saab Autos and Scania.
"Every use of the trademark had to be discussed," Scania spokesman Hans-Ake Danielsson told Automotive News Europe. "NEVS can't get hold of the Saab name until we've approved it. That is under discussion right now."
He added: "We have to protect our good name and brand. We have to be sure the new owner will not jeopardize that name."
