Burcon Announces Further Patent Grant; Provides Update On Activities

    VANCOUVER, Jan. 22 /CNW/ - Burcon NutraScience Corporation (TSX-V: BU)
announces today that it has been granted a United States patent over a process
for the production of flax protein isolates. The U.S. Patent - entitled
"Process for Preparation of Flax Protein Isolate" (US Patent No. 7,309,773)
covers an improved process for the production of flax protein isolates and
includes an initial step of removing mucilage from flax seed prior to flax oil
and protein removal. The innovations protected by this patent result in a
higher protein yield and an improved product.
    Burcon now holds a total of 8 U.S. patents which cover canola and flax
protein processing technologies and canola protein isolate applications and
has a further 34 patent applications currently filed with the U.S. Patent and
Trademark Office.
    Burcon has filed applications for most of its inventions internationally
under the Patent Cooperation Treaty of the World Intellectual Property
Organization. Together with patents issued in other countries, Burcon now
holds a total of 44 issued patents covering inventions that include the 8
granted U.S. patents. Countries in which Burcon holds issued patents or has
filed patent applications include Australia, Brazil, Canada, China, Hong Kong,
Japan, the European patent office, Mexico, New Zealand, Poland, South Africa,
South Korea and the United States. Currently, Burcon has approximately 200
additional patent applications that are being reviewed by the respective
patent offices in various countries worldwide. Although Burcon expends
significant resources and efforts to patent its discoveries and innovations,
there can be no assurances that any of Burcon's patent applications will
result in the issuance of patents, or any patents issued to Burcon will
provide it with adequate protection or any competitive advantages, or that
such patents will not be successfully challenged by any third parties.
    Mr. Johann Tergesen, Burcon's President and C.O.O. noted "Burcon's
strategy is to ensure that our innovative protein extraction technology,
applications of our proteins and the signature characteristics of Burcon's
proteins are protected on a worldwide basis. The U.S. patent office's grant of
our latest patent further strengthens our intellectual property portfolio."
    Burcon, in conjunction with Archer Daniels Midland ("ADM"), continues to
focus its development efforts on commercializing its lead canola protein
isolate products, Puratein(R) and Supertein(TM). Current development efforts
include the large-scale production of Puratein(R) and Supertein(TM) to
facilitate continued work with ADM's customers through the previously
announced material transfer agreements. Burcon's other main initiative is the
continuous pursuit of additional intellectual property opportunities. Burcon
continues to engage in research activities at its Winnipeg Technical Center
directed at optimizing its technologies with the goal of providing additional
patenting opportunities in the areas of processing, applications and compound
    In June 2007, Burcon announced its intention, in conjunction with its
license partner, to pursue regulatory recognition for Puratein(R) and
Supertein(TM) which process would include certain scientific studies,
including toxicology assessments -- such as feeding trials -- to be undertaken
by third party contract research organizations. Those feeding trials, along
with the required scientific studies, were initiated during the second
    The scientific studies are expected to be completed within the next
quarter and are being prepared to a standard to support the United States GRAS
affirmation process as well as to enable their use in making application for
regulatory approval under the Novel Foods process in the European community
and in other countries such as Canada.

    About Burcon NutraScience

    Burcon is a research and development company developing a portfolio of
composition, application, and process patents around its plant protein
extraction and purification technology. The goal of Burcon's research is to
develop its patented process to utilize inexpensive oilseed meals for the
production of purified plant proteins that exhibit valuable nutritional,
functional or nutraceutical profiles. Burcon, in conjunction with Archer
Daniels Midland, is currently focusing its efforts on developing the world's
first commercial canola proteins, Puratein(R) and Supertein(TM). Canola,
recognized for its nutritional qualities, is the second-largest oilseed crop
in the world after soybeans. Burcon's goal is to develop Puratein(R) and
Supertein(TM) to participate with soy, dairy, and egg proteins in the
expanding multi-billion-dollar protein ingredient market, with potential uses
in prepared foods, nutritional supplements, and personal care products.
