DuPont Sues SunEdison For Patent Infringement

E. I. du Pont de Nemours and Co. (DD: Quote) said Thursday that it has filed a patent infringement lawsuit against SunEdison and its affiliate NVT LLC in the U.S. District Court for the District of Delaware.

In its complaint, DuPont alleges that by sourcing and using photovoltaic cells and solar modules containing Samsung SDI Co., Ltd. front side metallization paste, SunEdison infringes DuPont's patented tellurium paste technology. The complaint also identifies Neo Solar Power of Taiwan as the cell manufacturer and Flextronics International Ltd. (FLEX) as SunEdison's contract manufacturer.
