Kyocera Sues Hanwha Q CELLS Japan For Solar Modules Patent Infringement

(RTTNews) - Kyocera Corp. (KYO) said Thursday that it filed a complaint in Tokyo District Court today against Hanwha Q CELLS Japan Co., Ltd., for infringement of a Kyocera patent relating to solar modules.

The complaint was filed after extensive negotiations regarding Kyocera's Japanese patent for a "three-bus-bar electrode structure" that increases energy conversion efficiency in solar modules.

Kyocera noted that it is negotiating with other parties regarding the patent.

Kyocera said it has conducted continuous research and development of solar energy technologies since 1975. The "three-bus-bar electrode structure" patented by Kyocera in March 2012 has been a key technology utilized in the company's solar cells since setting a world record for energy conversion efficiency in 2004.
