BASF files a lawsuit against DuPont for infringement of BASF's patented technology.

BASF files a lawsuit against DuPont for infringement of BASF's patented technology that confers tolerance to a key class of herbicides.

It claims DuPont's Optimum GAT corn product incorporates BASF's patented promoter which is an important genetic component that enables successful tolerance toward the herbicide class known as AHAS or ALS inhibitors.

BASF Plant Science seeks to declare invalid and unenforceable DuPont patents for technology relating to herbicide tolerance.

DuPont tiles a lawsuit against BASF claiming it is infringing four patents relating to biotechnology traits similar to those used in DuPont's proprietary Optimum GAT trait.

The patents listed in the lawsuit confer tolerance to a herbicide class with characteristics known as ALS inhibitors and pertain to certain methods for controlling weeds.

Through the lawsuit, DuPont is requesting BASF acknowledge the validity of DuPont's patents related to the ALS tolerance trait and provide the company reasonable compensation for their use. DuPont is also asking the court to declare BASF patents on a trait promoter invalid and rule that DuPont does not infringe those patents when it uses its own proprietary trait in ALS tolerant crops.
