Vancouver, British Columbia--(Newsfile Corp. - October 20, 2022) - Burcon NutraScience Corporation (TSX: BU) ("Burcon" or the "Company"), a global technology leader in the development of plant-based proteins for foods and beverages, is pleased to announce that it has received a notice of allowance from the United States Patent and Trademark Office ("USPTO") for a patent application covering the unique process to produce high-purity protein ingredients from non-soy oilseed, which includes the use of sunflower seed as the source material. A notice of allowance from the USPTO is a written notification that a patent application has cleared internal review and is pending issuance and will grant in the near future.

"We are pleased to receive this sunflower patent allowance, which further validates Burcon's innovative capabilities to develop leading edge next-generation protein technologies," said Peter H. Kappel, Burcon's interim CEO and Chairman of the Board, adding, "We continue to strengthen our IP portfolio but more importantly, we are developing unique processes to produce upcycled protein ingredients that offer a sustainable and economical way to feed the world."

U.S. patent application 16/071,653, which covers the unique processes to produce protein isolates from canola, sunflower, hemp, safflower, cottonseed, flax, sesame, mustard and peanut or any oilseed product or by-product derived from processing of non-soy oilseeds, was allowed on July 19, 2022 and will be soon issued as a U.S. granted patent. This patent allowance adds to Burcon's existing patent portfolio of 331 issued patents in various countries, including 72 issued U.S. patents, and in excess of 175 additional pending patent applications, 26 of which are U.S. patent applications.
