美国太阳能电池板制造商第一太阳能周四起诉中国晶澳太阳能和康宁的一家太阳能子公司，扩大了其专利执法行动。此前该公司上月宣布将把重心从联邦贸易案件转向诉讼。
US solar panel maker First Solar sued China's JA Solar and a solar subsidiary of Corning on Thursday, expanding its patent enforcement campaign after announcing last month that it would shift its focus from a federal trade case to litigation.
