On 10 April, AMSC lodged an appeal claim with the Supreme People’s Court in Beijing, mainland China’s highest court, over the Hainan Higher Court’s 5 April dismissal of one of AMSC’s suits accusing Sinovel of intellectual property (IP) theft.
The original judgement dated back to February, when AMSC's lawsuit against Sinovel over infringement of computer software copyright was rejected.
In October 2011, Sinovel was added by Hainan first intermediate people’s court as a third party into an AMSC lawsuit against Dalian Guotong Electric and Huaneng Hainan Electric Power Generation. In December, Sinovel was added as a defendant.
In response, Sinovel objected to its inclusion in the lawsuit to the Hainan court stating it was outside the court's juristiction.
At the time, AMSC downplayed the Hainan case. It described it as the "smallest" of its actions against Sinovel because it involves a demand for 'only' $200,000 damages.
Overall, AMSC is seeking a total of $1.2 billion from Sinovel in damages and lost shipment payments in three civil cases and one arbitration dispute.
