BASF Sues MANA, Cheminova Over Fipronil

NEW YORK — BASF SE has sued rival chemical manufacturers Makhteshim Agan North America and Denmark-based Cheminova over patent infringement for fipronil, reports Reuters. Both company’s were preparing to sell generic versions of the insecticide, which is scheduled to go off-patent in August this year. BASF says it has another set of patents related to the manufacturing process. These patents prevent a competitor from marketing a generic version of the pesticide.

Bayer CropScience, which originally manufactured fipronil and kept some patent rights after BASF purchased the business in 2003, has joined BASF in the lawsuits.


Fipronil is used for control of insects that attack potato crops, as well as for residential use on termites.
