In filings to the U.S. district court in Delaware, Deere alleged that products made or sold by Precision Planting, including vSet seed meters along with SpeedTube products, infringed on its patents.

The company said the patents protected its inventions that facilitate accurate seed placement, uniform seed spacing and even crop emergence.

“Deere has suffered damages as a result of the direct and indirect infringing activities of Defendant and will continue to suffer such damages as long as those infringing activities continue,” the company said in the lawsuit.

According to the lawsuit, the company is seeking unspecified damages.

AGCO acquired Precision Planting in September 2017.

Kelli Cook, a spokeswoman for both AGCO and Precision Planting declined to comment on the litigation.

AGCO bought Precision Planting from Monsanto Co MON.N after the world's largest seed company terminated its agreement to sell the unit to Deere.

Shares of Deere closed up 2.6 percent at $153.39 on Friday. AGCO’s stock ended the day up 1.2 percent at $64.34.

The cases are: Deere & Company v. AGCO Corporation in the United States District Court for the district of Delaware, No. 1:18-cv-00827-UNA and Deere & Company v. Precision Planting LLC in the United States District Court for the district of Delaware, No. 1:18-cv-00828-UNA.
