Google has been trying to establish its trademark worldwide, but has encountered some problems on the way. In Europe for example the company G-Mail (www.gmail.de) has already been registered for six years. Due to this fact Google cannot use the domain gmail.de and had to rename the service in Europe to googlemail instead of Gmail.
Recently Google encountered a similar problem in China, as the domain gmail.cn is also already taken. ISM Technologies which claims to be china’s largest domain registrar and is backed by the Chinese government refuses to sell the domain. Google has also had problems with domains recently in Poland with the domain gmail.pl, however the case in China may be more problematical given that intellectual property issues in China can become complicated by politics. The Chinese gmail.cn website also offers mail services. Google has no t yet tried to sue the company.
In china Google has already owns web addresses such as google.cn or google.com.cn and is competing with the local search engine Baidu (www.Baidu.com).
