Tesla Motors are now selling Model S sedans in China, but without a local name for its brand because of an old trademark dispute.

Tesla originally wanted to use “Te Si La”, the Chinese name best known among local consumer, but the name has been registered by a Chinese businessman who has been refusing to give up the trademark.

Zhan Baosheng registered “Te Si La” in 2006 and has no intentions to sell the trademark despite a series of requests from potential buyers, his agent said. A Tesla salesman quoted by Reuters said the carmaker has no Chinese name yet and there’s no information regarding when or whether there will be one.
