A lesson for marketers taking their brands global, especially relating to the Chinese market.

French luxury goods group LVMH said on Wednesday it is looking into a report that a Chinese man has won patent approval for the Chinese translation of the Louis Vuitton brand.

Wang Jun, a businessman in the central city of Wuhan, had won the right to the brand name Lu Yi Wei Deng despite protests from Louis Vuitton, a local newspaper reported.

"Our legal department is looking at this," Janie Zhuang, a Louis Vuitton spokeswoman in Shanghai, said.
