Google China has registered 44 Google-like domain names in China so far, an act to prevent speculators to grab some other Chinese characters, but similar pronunciation to Google, such as 咕咕, 库高, 古歌, and 谷果. Meanwhile, a Chinese firm based in Beijing with the same 谷歌 name has sued Google China 谷歌信息技术（中国）有限公司, i.e. www.google.com.cn over the same name used, according to this article in China (in Mandarin), claiming that the name Google China used, i.e. 谷歌 has interrupted its daily office operations due to numerous calls received everyday for the Google search engine’s inquiry. Both companies used 谷歌 as the main name of the company.
