DEVENS, Mass. – AMSC, a global solutions company serving wind and grid leaders, announced that it has filed an appeal with China's Supreme People's Court relating to the Hainan Higher Court's decision on April 5, 2012, to uphold the Hainan Province No. 1 Intermediate People's Court's dismissal of AMSC's civil case against Sinovel Wind Group Co. Ltd. (Sinovel) and Dalian Guotong Electric Co. Ltd. (Guotong). This is the smallest of four legal actions AMSC has brought against Sinovel. In total, AMSC is seeking to recover from Sinovel more than $1.2 billion for contracted shipments and damages in these cases, which stem from Sinovel's contractual breaches and AMSC's discovery of intellectual property theft by Sinovel employees.
