DuPont files lawsuit against SunEdison, alleges infringement

file

On Thursday, DuPont (NYSE: DD) filed a patent infringement lawsuit against SunEdison (NYSE: SUNE) and its affiliate NVT LLC in the U.S. District Court for the District of Delaware.

DuPont alleges that SunEdison infringed DuPont's patent tellurium paste technology by sourcing and using photovoltaic (PV) cells and solar modules containing Samsung SDI Co. Ltd. front side metallization paste.

"DuPont will enforce its patent rights to protect our substantial investment in innovation to improve solar energy efficiency," said Peter Brenner, global PV business marketing manager, Microcircuit Materials, DuPont Electronics & Communications.  "Our patented tellurium technology is available only from DuPont; no other PV paste manufacturer has a license to use our patented technology."

The complaint also identifies Neo Solar Power as the cell manufacturer and Flextronics as SunEdison's contract manufacturer.
