BEIJING - A government official said Thursday that China's crackdown on infringements of intellectual property rights (IPR) had scored successes and China will work harder to protect the rights and interests of Chinese and foreign trademarks.

Since the Chinese authorities launched a campaign in October to improve the protection of IPR, a total of 3,010 cases of infringement and counterfeiting had been reported, said Fu Shuangjian, vice-minister of the State Administration for Industry and Commerce (SAIC).

The crackdown had also resulted in the revocation of 103 business licenses in the country, said Fu at a news conference.

Li Jianchang, head of the department of trademarks with the SAIC, said at the briefing that a total of 38,000 applications for trademark registration have been rejected for infringing existing trademarks, including foreign ones, during the two months.

"We will work hard, as always, to safeguard the interests and rights of the trademarks of both Chinese and foreign-invested enterprises," Li said.

In the five years from 2006 to 2010, Chinese authorities had dealt with 242,000 cases of infringement and counterfeiting of trademarks, and foreign trademarks were involved in 49,000 cases, Fu said.
