A Chinese firm is suing the internet giant Google over its Chinese name, saying it is too much like its own name and is harming its business. Google's Chinese subsidiary has transliterated its name to Guge. Beijing Guge Science and Technology Ltd told Reuters news agency that people were constantly phoning its office trying to contact search engine Google. "We just want Google to change their commercial name," said Tian Yunshan of Beijing Guge. Mr Tian said that people looking for Google in a local telephone directory assistance service were directed to his company because Google is not listed.
