Bayer CropScience has filed a patent infringement lawsuit in the US District Court for the Eastern District of Virginia against Dow AgroSciences (DAS) based upon DAS's unauthorised use of Bayer patents related to glufosinate-tolerance technology (Liberty Link).
The lawsuit asserts infringement of four Bayer patents and follows two previous claims involving seven Bayer glyphosate-tolerance technology patents and Bayer's 2,4-D herbicide tolerance patent.
Those proceedings are currently underway before federal courts in Delaware and New Jersey (US). As part of the lawsuit, Bayer has requested a permanent injunction against DAS's unauthorised use of its glufosinate resistance technology.
Margaret Keating, associate general counsel for Bayer CropScience, said: "Bayer CropScience invests heavily to provide growers with innovative technology solutions and remains resolute in our determination to enforce our intellectual property rights."
Bayer's actions in defence of its glufosinate-tolerance, 2,4-D herbicide tolerance and glyphosate-tolerance technology patents and stacking of such technologies followed announcements made by Dow AgroSciences regarding its Enlist Weed Control System.
