DuPont sues BASF over herbicide patents
June 1, 2009
According to MarketWatch, Wilmington, Del.-based DuPont Co., has filed a lawsuit charging BASF with infringing four patents tied to a class of herbicides. In a statement on Monday, DuPont said it filed the suit in U.S. District Court for the District of Delaware. In the lawsuit, DuPont asks BASF, the Ludwigshafen, Germany, chemicals producer, to recognize the patents as valid and pay "reasonable compensation" for using them. At the same time, DuPont said it is asking the court to declare certain BASF patents invalid and to rule that DuPont does not infringe those patents when it uses its own technologies. DuPont said it tried to negotiate the issue with BASF, to no avail.
