BEIJING - China registered 4.6 million trademarks at the end of 2010, with the number of trademark applications exceeding 1 million last year, according to the State Administration for Industry and Commerce.

Despite the huge number, only one out of eight economic entities in China had a trademark and there are not many famous brands, according to the administration.

Meanwhile, trademark infringement cases took place often as a lot of enterprises were not fully aware of trademark protection, according to official sources.
