DSM wins patent infringement case against Lallemand related to low-glycerol yeast technology applicable in ethanol production

Parsippany NJ, US, 16 May 2018 18:45 CEST

Royal DSM, a global science-based company active in health, nutrition and materials received unanimous jury verdict in a Federal Court in Wisconsin concluding that all glycerol reducing ethanol yeast products sold by Lallemand infringe DSM’s US Patent 8,795,998.

After several failed attempts between the parties to settle out of court, DSM filed suit against Lallemand for infringement of its patent in US Federal Court in Wisconsin. DSM alleged that Lallemand’s glycerol reducing yeast products including Transferm Yield+ and YP3 used in the production of ethanol, infringes DSM’s US 8,795,998 patent. After 7 days of trial the jury concluded that the DSM patent is valid and is being infringed by Lallemand’s glycerol reducing yeast products.

DSM’s yeast technology for starch conversion provides consistent increased ethanol yields and significantly reduces glycerol production. DSM’s yeast is commercially available in dry and cream forms, serviced by our local technical team, and manufactured in the United States.

We are happy with the outcome of the case. Our focus is to bring customers the latest in yeast technology allowing them to deliver the best fermentation results,” says Atul Thakrar, President of DSM Bio-based Products & Services. “Continual development and protecting this intellectual property is a key component of our strategy that supports our significant biofuel investments. We are committed to deliver differentiating yeast and enzyme technologies that enable biofuel plant owners to optimize their processes and maximize their yields and profits in a sustainable way.”

DSM remains committed to growing and protecting its portfolio of more than 35 patent families for the biofuels industry in the United States and around the world.
