DuPont announced recently that it has settled patent infringement litigation against Bio-Rad Industries of Hercules, California.



The patents-in-suit related to low-heat generating fluorometer devices usable in assays based on Polymerase Chain Reaction (PCR) technology, such as the BAX System from DuPont Qualicon.



Under the settlement, Bio-Rad was granted a non-exclusive license to the DuPont patents. Other terms of the settlement were not disclosed.



‘DuPont has a long heritage and commitment to developing sustainable products for this industry,’ said Kevin Huttman, president of DuPont Qualicon. ‘To continue with future innovations, we must protect our investment in this technology through aggressive assertion of our patent rights when we believe they are being violated.’


DuPont Qualicon sells DNA-based microbial detection systems covered by the DuPont patents under the trade name BAX System. In the food industry, this system can be used to test samples for contamination with microorganisms.
