Cadbury might be a household name for chocolate in most of the world, but some mainland farmers are more familiar with it as a brand of fertiliser. And that's got Kraft Foods, owner of the famous chocolate brand, embroiled in a trademark dispute in a Beijing court. Gaosheng Science and Technology, a firm based in Changsha, Hunan, has registered a line of fertiliser products under the trademark Ji Bai Li, the Chinese translation of Cadbury. Cadbury China has taken the case to the Beijing No 1 Intermediate People's Court, demanding the State Administration of Industry and Commerce's Trademark Appeals Board rule on whether Cadbury qualifies for well-known trademark status on the mainland. The board earlier ruled against Cadbury's demand to invalidate the fertiliser trademark. Cadbury argued it should be withdrawn on the grounds that it misled consumers and diluted the Cadbury brand. However, the board said the Chinese trademark in dispute would not lead to confusion and harm Cadbury's business, because fertilisers and confectionery were two very distinct product categories. But if Cadbury is deemed to have well-known trademark status, it may resort to a clause under Chinese trademark law that protects well-known trademarks even if products in dispute are of different nature, the Legal Daily reported. Both Kraft and Gaosheng were unavailable for comment yesterday, Hangzhou lawyer Xu Zhihui , who specialises in the protection of intellectual property rights, said Cadbury should have sought to register as many categories of products under its brand as possible for better protection. 'My suggestion is that Cadbury should argue for a well-known trademark status and then its trademark will be much better protected in China,' Xu said. However, he said a global brand did not automatically become a well-known trademark in China. For example, South Korean carmaker Hyundai had been forced to buy its Chinese-language trademark from a Chinese client before it could enter the local market. IPR specialist Professor Li Shunde , from the Chinese Academy of Social Sciences, said the need to consider well-known trademark status for an international brand was open to interpretation by the industry and commerce administration.
