China-based solar manufacturer and spun off of SunPower, Maxeon Solar Technologies Ltd has filed a lawsuit in the Tokyo District Court, Japan against Canadian Solar Japan K.K., the Japanese unit of Chinese-Canadian PV for patent infringement.
The plaintiff alleges that the defendant violated its Japan patent No. JP6642841B2 for shingled solar modules without permission or license.
The plaintiff reportedly accused the defendant infringed on its shingled solar cell panel technology used to deploy solar panels it manufactures and sells under the SunPower Performance brand name.
Canadian Solar Japan is a wholly-owned subsidiary of Canadian Solar Inc., which is headquartered in Canada with operations and production facilities in China and in South-East Asia.
The plaintiff reportedly that the Performance panel architecture and manufacturing processes were pioneered by Silicon Valley-based Cogenra Solar that was acquired by SunPower in 2015.
The plaintiff reportedly said that it has continued to use the SunPower brand in over 100 markets, manufactures Performance solar panels in China through a joint venture with Tianjin Zhonghuan Semiconductor Co Ltd (SHE:002129).
“We’ve built our business on a 35-year foundation of pioneering solar innovation. The intellectual property behind our shingled solar cell technology was developed by our talented design and engineering teams and is the result of substantial investment, the resultant Performance technology outperforms conventional panels in efficiency, power, reliability, and aesthetics.” Jeff Waters, Maxeon CEO reportedly said.
The plaintiff reportedly said that the legal action is meant to safeguard its valuable assets and prevent unauthorized use of its intellectual property.
The plaintiff seeks a jury, permanent injunction, and payment for damages.
The case is ongoing.
