Giang Son Joint Stock Company has announced it intends to sue the Big C supermarket chain for violating the trademark of Yen The chicken.

"We found that BigC Supermarket chain has developed a range of Yen The branded chicken as its own product, but they’re cheaper than ours. The supermarket sells the chickens for just VND120,000 (USD5.7) per kilogramme compared to VND150,000 (USD7.14) at other supermarkets,” he said, raising doubt over the supermarket’s chicken sources.

The company has urged management agencies to stop the supermarket’s Yen The chicken sales to protect its rights.

As of January 22, the supermarket had continued to sell Yen The chicken.

Meanwhile, Luu Xuan Vuong, Chairman of Yen The People's District said the district had not yet signed any contracts with the BigC Supermarket over the Yen The chicken trademark.

BigC's communication officer Nguyen Thi Thanh Huyen said her department was not responsible for answering media questions and that the company would issue a statement at a later date.

Yen The district has a reputation for free-range chicken.

The district alone produces 13-15 million fowl a year with an annual output of 17,000 tonnes of chicken. The business involves more than 3,000 local households.
