Hubei Feilihua Quartz Glass (SHE:300395) received a retrial response notice from China's Supreme People's Court after defendants Wuhan Xinyoutai Optoelectronics, Xiao Zhengfa and Chen Yiping filed for retrial challenging a previous Supreme Court ruling.
The case concerns alleged infringement of technical secrets, with 202.4 million yuan at stake, according to a Thursday filing with the Shenzhen bourse.
The original second-instance judgment, which was favorable to the company, remains enforceable during the retrial review.
