PureCircle, an American sweetener producer, is the "godfather" of the sweetener industry, founded in 2001

Prior to this, PureCircle was in constant

In 2018, PureCircle accused Sweegen of infringing a patent (U.

According to PureCircle, Sweegen's Reb M sweetener is manufactured through a biotransformation process developed by partner Conagen that PureCircle claims infringes its patents

At the time, Sweegen responded that it had been granted 13 patents and more than 130 patent applications for stevia sweeteners worldwide, including at least seven "new methods"

Reb M is a zero-calorie, zero-calorie sweetener that is 300 times sweeter than sugar and 300 times sweeter

Of the 30 steviol glycosides in stevia, Reb A is the highest, while Reb M is very low in plant dry leaves (about 0.

Of the 30 steviol glycosides in stevia, Reb A is the highest, while Reb M is very low in plant dry leaves (about 0.

Reb A is the sweetest of all natural compounds in stevia leaves, but with a slightly bitter licorice or fennel flavor; The main advantage of Reb M is that it is completely bitter

This has prompted companies to produce more cost-effectively through genetic engineering, or to use enzymes to convert more abundant steviol glycosides extracted from stevia leaves into scarcer glycosides, such as Reb M

In late 2019, after the U.

However, after four years of deliberation, the U.

In response, Sweegen CEO Steve Chen said, "The court's may 24 judgment effectively ended the lawsuit

In recent years, the production methods of stevia sweeteners have included a variety of: direct extraction from stevia; A sweetener made from stevia extract, and then undergoes an enzymatic transformation process to obtain a better taste of steviol glycosides; Made from genetically engineered microbial fermentation sugars, Cargill and DSM collaborate in this area to produce Eversweet Reb M through the Avansya joint venture; Ingredion has an exclusive license to sell and market Amyris' "Realsweet" Reb M, which is also produced

In 2020, Japanese stevia pioneer Morita Kagaku Kogyo Co even issued a press release highlighting the scope of its intellectual property around Reb M and naming the three partners that licensed the technology (Cargill/DSM JV Avansya, Ingredion, and Tate & Lyle).

Nonetheless, PureCircle has lost the case temporarily and plans to appeal
the relevant judgment.
"We are disappointed by the court's ruling and we intend to appeal to continue to vigorously defend our intellectual property," a relevant spokesperson for Ingredion said
