PureCircle Confirms Scientific Leadership with Industry's First Published Commercially Viable High Purity Stevia Patents

CHICAGO, Dec. 9, 2010 /PRNewswire/ -- PureCircle (LSE: PURE) the world's leading producer and marketer of high purity stevia products today confirms the continued expansion of its patent portfolio with the grant of three patents by the U.S. Patent and Trademark Office.

The three patents cover a wide range of process and methods across PureCircle's entire stevia product portfolio and date back as early as December 21st, 2004, which pre-dates any other published patents relating to commercially viable high purity stevia manufacturing process or product application. As a result, to its customers'  and partners' benefit, PureCircle is in a strong position to operate freely with its market pioneering processes and defend its patents against any potential infringements across all aspects of the high purity stevia industry.

Specifically, the technologies in these patents establish the process that can be used for manufacturing high purity steviol glycoside extract (SG95) and different components, such as Reb A and Stevioside, that could not be achieved with earlier technology on a commercial scale.  As part of these patents, the processes and methods for developing PureCircle's highly consistent products such as Reb A 97, SG95 and enzyme treated stevia products are covered, including their usage across the entire breadth of product categories, from food and beverage to cosmetics.

The approval of all three patents to PureCircle confirms formally the Company's clear scientific leadership in the global high purity stevia industry.

Commenting on the publication of the patents, Magomet Malsagov said, "The publication of these patents confirms clearly our prior science across the high purity stevia industry and underpins our global market leadership. The USA patent grant is a strong endorsement in PureCircle as the right partner of choice for our strategic customers and sugar partners. PureCircle continues to invest in the science of high purity stevia and we have a strong portfolio of applications in development."
