Burcon Awarded Third U.S. CLARISOY Patent In Two Months

VANCOUVER, British Columbia, April 11, 2013 (GLOBE NEWSWIRE) -- Burcon NutraScience Corporation (TSX:BU) (Nasdaq:BUR), a leader in functional, renewable plant proteins, has been awarded U.S. patent No. 8,409,654 for a process used to produce CLARISOY ™ soy protein.

The award marks the third U.S. patent received by Burcon within the last two months for processes used to produce CLARISOY soy protein, and it supports CLARISOY as the first plant-based protein extraction technology able to deliver high-quality nutrition in low pH beverages, like sports drinks and juices, along with unmatched transparency, solubility and clean taste.

"Our patent strategy for CLARISOY since day-one has been to protect our valuable intellectual property through a comprehensive patent structure," said Johann F. Tergesen, Burcon's president and COO. "Burcon's major asset is our intellectual property, as demonstrated by the license agreement we signed with Archer Daniels Midland Company for the worldwide production, distribution and sale of CLARISOY soy protein."

Burcon's intellectual property strategy for CLARISOY focuses on protecting the commercial opportunity of having the world's first plant-based protein capable of offering both clarity and high-quality protein nutrition in low pH beverages. "CLARISOY's unique functional and nutritional attributes are what drive its strong commercial value," noted Tergesen. 

To protect this commercial value, Burcon has filed numerous patent applications along three patent categories:

Process: covering technologies for protein extraction and purification.

Use: covering various commercial applications, e.g., CLARISOY as a functional nutrient in sports drinks.

Composition of matter:  covering the "signature characteristics" of its products, e.g., the specific measure of CLARISOY solubility at various pH ranges.

In addition to U.S. patent applications, Burcon has applied for international protections of its intellectual property in some 35 countries under the Patent Cooperation Treaty of the World Intellectual Property Organization, including in the European Union, Japan, China, India, Australia, New Zealand and Canada. 

Burcon's patent portfolio now consists of 225 issued patents in various countries, including 39 in the U.S., as well as more than 400 active patent applications, including 80 additional U.S. patent applications.

CLARISOY soy protein is the world's first plant-based protein capable of offering both clarity and high-quality protein nutrition in low pH beverage systems.  CLARISOY is under exclusive license to Archer Daniels Midland Company (ADM), which offers a range of products for both low and neutral pH applications, allowing food and beverage companies to easily include up to 10 grams of CLARISOY per 500mL serving. 

ADM's CLARISOY-based products include CLARISOY 100, a premier vegetable-based protein that offers both clarity and high-quality protein nutrition for beverages with a pH of less than four. Extremely heat stable, CLARISOY 100 requires no homogenization or stabilizers in low pH beverages. It is specifically designed to enable beverage manufacturers to meet the demand for great-tasting, nutritionally enhanced beverages by the growing number of health and wellness oriented consumers. Applications include sport nutrition beverages, citrus-based drinks, fruit-flavored beverages, fruit-juice blends, lemonades, powdered beverage mixes and fortified waters.

CLARISOY 150 is a revolutionary soy protein for neutral pH beverages and low pH beverages with cloud systems. The clean flavor and smooth mouth-feel makes CLARISOY 150 a formulator's ideal protein ingredient.
