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.
