DuPont Co. on Thursday filed a patent infringement lawsuit
against SunEdison Inc. and its affiliate NVT LLC, alleging the
solar technology company is infringing on DuPont's patented
tellurium paste technology.
A representative for SunEdison didn't immediately respond to a
request for comment.
DuPont alleged that by sourcing and using photovoltaic cells and
solar modules containing Samsung SDI Co. front-side metallization
paste, SunEdison was infringing on DuPont's patent.
"DuPont will enforce its patent rights to protect our
substantial investment in innovation to improve solar energy
efficiency, " said Peter Brenner, global photovoltaic business
marketing manager, Microcircuit Materials, DuPont Electronics
Communications.
The Wilmington, Del., chemical and agricultural company has been
pivoting away from lower-growth commodity businesses toward
higher-growth areas, such as nutritional products and agriculture.
As part of the effort, DuPont last year said it plans to spin off
its performance-chemicals segments, which makes materials for
nonstick frying pans and house paints.
Profits at DuPont climbed 3.9% in the second quarter, though
operating earnings fell due to lower profits from the seed
business, the company reported last month.
