Pressure BioSciences, Inc. Issued First Patent in Canada

WEST BRIDGEWATER, Mass., Aug. 30 /PRNewswire-FirstCall/ -- Pressure BioSciences, Inc. (Nasdaq: PBIO) ("PBI") today announced that it has been issued its first patent by the Canadian Intellectual Property Office. Entitled "Pressure-Mediated Binding of Biomolecular Complexes" (Number 2,259,318), this issuance extends the coverage of the Company's pressure cycling technology (PCT) patents previously issued in the United States, Japan, Germany, Italy, France, Sweden, Switzerland, and the U.K. The PCT methods covered by this patent relate to the association and disassociation of biomolecular complexes (such as antigen/antibody complexes) and the separation of biomolecules (such as proteins) from complex mixtures. Such methods may better enable the separation and purification of biomolecules (procedures that are performed routinely in pharmaceutical, biotechnology, and research laboratories) and may also improve the speed and sensitivity of both research and diagnostic tests, such as those used worldwide in the cancer, endocrine, and infectious diseases areas.

Richard T. Schumacher, Founder, President, and CEO of PBI said: "We continue to focus our primary PCT efforts in the potentially large and rewarding area of sample preparation. We concomitantly look to add value by reviewing our extensive patent portfolio outside of sample preparation to determine if our PCT intellectual property may help others improve their efforts in the therapeutic, diagnostics, or research areas."

Schumacher continued: "The PCT methods covered by this patent have the potential to play a significant role in improving the speed, ease-of-use, and sensitivity of both diagnostic and research tests currently used in laboratories today. The addition of Canada to the list of countries in which patents with similar claims have already been issued adds measurably to the value of this exciting PCT application."
