DuPont (DD) filed a lawsuit against Heraeus Materials Technology LLC and its customer SolarWorld Industries America, Inc. in U.S. Federal Court for the District of Oregon for infringing a recently issued DuPont patent regarding front-side metallization paste compositions used in solar cell technology. DuPont, in its complaint, stated that Heraeus and SolarWorld infringe DuPont U.S. Patent No. 8,158,504 B2, by manufacturing, selling and/or using Heraeus front-side silver pastes.
David Miller, president, DuPont Electronics & Communications noted, "The advances we have made in the field of front- and back-side metallization contacts have resulted in significant efficiency gains for solar cell technology. This case demonstrates that DuPont will act swiftly to enforce our intellectual property rights against any infringers and protect our investment and commitment to DuPont shareholders and customers."
The lawsuit follows another patent infringement suit DuPont filed against Heraeus in September 2011, which is ongoing.
