Kyocera, Q Cells Japan settle patent infringement lawsuit


Last July, Kyocera filed a lawsuit at the Tokyo District Court against Q Cells Japan for allegedly infringing on its three-busbar solar PV technology, following a breakdown in negotiations between the two parties.

Kyocera patented the technology (Japanese patent no. 4953562) for the three-busbar electrode structure, which increases solar module efficiencies, in March 2012. Following the lawsuit, Q Cells issued a statement reassuring its customers that its products, applications and solutions would remain unaffected.

In a statement today, Kyocera said the two parties had settled the dispute, having concluded a technology licensing agreement. "The agreement features a license for Kyocera’s Japanese patent related to a ‘three-bus-bar electrode structure’ that increases energy conversion efficiency in solar modules … and also includes a mutual exchange of patent licenses between the two companies to be executed in the future," said Kyocera.
