Protection in focus with Danyang Glasses mark

To many Chinese consumers, especially those who wear spectacles, the city of Danyang in Jiangsu province is known as "the city of glasses".

But it wasn't until the end of last year that the Danyang Glasses collective mark was approved for local manufacturers and retailers to protect their rights.

Some 2,600 companies and 60,000 employees produce and retail eyeglasses in Danyang, making it the biggest industry in the city. More than 2,800 trademarks have been registered in the sector including eight national well-known trademarks.
