Monsanto sues DuPont/Pioneer over Optimum GAT

Monsanto has filed a lawsuit against DuPont and its seed subsidiary, Pioneer Hi-Bred International, over the use of its technology in Pioneer’s genetically modified herbicide-tolerant Optimum GAT soybeans and maize. Monsanto claims that Pioneer’s stacking of Monsanto’s Roundup Ready glyphosate tolerance trait with Optimum GAT lines infringes Monsanto patents and breaches existing licensing deals. The companies have been seeking to resolve the issue out of court since December 2008 ( Agrow No 566, p 2).
