29 Oct 2019 --- Stevia producers SweeGen and PureCircle are scheduled to be in an upcoming litigation, with results to be decided by the US Federal District Court. This follows PureCircle’s filing of a complaint alleging patent infringement by SweeGen in the production of Rebaudioside M (Reb M), a “next-generation” sweetener with a taste profile like sugar. A decision from the Patent Trial and Appeal Board (PTAB) of the US Patent and Trademark Office (USPTO) has since been issued in favor of PureCircle.
