BEIJING, Nov. 14 (Xinhua) -- Beijing has cracked down on 2,334 trademark infringement and fake commodity production cases and confiscated over 102 million yuan (about 14.67 million U.S. dollars) so far this year, local authorities said Wednesday.

According to the Beijing Administration for Industry and Commerce, 237 cases that infringed the trademarks of companies including Apple, Mercedes-Benz, BMW and Royal Dutch Shell have been investigated and punished.

A Beijing-based company was slapped with a fine of over 55.87 million yuan for illegally using the trademark of Japanese footwear company Onitsuka Tiger, which is the biggest trademark infringement case in Beijing in the past 20 years, the sources said.

Recently, Beijing has been deepening law enforcement cooperation in the Beijing-Tianjin-Hebei region to crack down harder on online copyright infringement and to strengthen protection of the exclusive use of foreign trademarks.
