When DuPont wasn’t able to create a product that could compete with “Roundup Ready,” it created a product that combined its own technology with that of Monsanto, the original “Roundup Ready” manufacturer. Monsanto sued DuPont for patent infringement, resulting in a settlement in which DuPont agreed to pay Monsanto $1.7 billion over ten years in exchange for a licensing agreement. One of DuPont’s stockholders, a Pennsylvania pension fund, brought a derivative suit against DuPont for breach of fiduciary duty in connection with DuPont’s “combined technology” product. In May 2015, the Delaware Chancery Court dismissed the derivative lawsuit, but another investor attempted to revive the derivative suit. The Chancery Court said the investor failed to show that the board’s refusal to take legal action was an invalid exercise of business judgment. On January 28, 2016, the Chancery Court affirmed the dismissal of the derivative suit.
