Bauer Energy Design® Inc. ("Bauer" or the "Company") is pleased to announce today that the U.S. Patent and Trademark Office has granted US Patent No. 7,547,413 to Bauer. This U.S. patent includes broad claims to novel methods and systems and their use in disinfecting or sterilizing a surface, an object or an environment with a special treated water steam.

Advanced Vapor Technologies LLC provides a 'water-only' steam vapor process, scientifically proven to rapidly eradicate MRSA, VRE and C. difficile spores and much more. This process is safer and faster than chemical disinfectants, non-consumptive, while using green, clean technology

Bauer Energy Design® Inc. ("Bauer" or the "Company") is pleased to announce today that the U.S. Patent and Trademark Office has granted US Patent No. 7,547,413 to Bauer. This U.S. patent includes broad claims to novel methods and systems and their use in disinfecting or sterilizing a surface, an object or an environment with a special treated water steam.

The issuance of this patent provides broad patent protection for our water and steam vapour processing system and creates commercial opportunities for Bauer and his licensees in a broad commercial space. "Our system has applications in industry, including health care, livestock farms, meat processors, food manufacturers, food service facilities, schools and universities, as well as in domestic households," said Walter J. Bauer, President of the Company. Bauer's patent portfolio now includes one issued patent and two patent applications pending in multiple jurisdictions throughout the world.

Surface-mediated infectious disease transmission is a major concern in a variety of settings, including schools, hospitals, and food-processing facilities. Chemical disinfectants frequently used to reduce contamination pose significant risks to humans and the environment. Some microorganisms have natural resistance to chemical disinfectants which operate over a narrow range of pathogens. Additionally, the chemical formulations require long dwell or exposure times which are often overlooked during application. Autoclave-based sterilization does not create natural resistance and it consists of exposing a material to very high temperatures for a long period of time. However, not all materials and environments can be autoclaved.

Bauer's new U.S. patent includes claims to an enhanced type of steam vapour that can effectively kill a broad range of microorganisms within 3 - 5 seconds, reduce surface-mediated infection risks, and serve as a green, more effective alternative to chemical disinfectants and steam-autoclaves.

Advanced Vapor Technologies LLC (AVT) of Edmonds, WA pioneered the use of this patented steam as a hard surface disinfection protocol (TANCS®), and is the licensee for this application. The protocol is suitable for a wide range of cleaning and disinfection issues not readily addressed by traditional chemical disinfectants.

This U.S. patent was filed based on the successful results demonstrated in numerous studies across a variety of surfaces and environments susceptible to microbial infection.

The steam vapour protected by this U.S. patent is "unique." The studies included in the U.S. patent show that this "unique" steam has superior ability to reduce growth of microorganisms to that of untreated water vapour at lower temperatures (50oC). Furthermore, microorganisms are unable to grow on surfaces sprayed with water treated in accordance with the methods of the patent, but they can grow on surfaces sprayed with untreated water.

Results achieved in disinfecting contaminated hard surfaces with this novel steam vapor system with TANCS®, and protected by the U.S. patent, were peer reviewed and published in the scientific American Journal of Infection Control (AJIC, 2009 Feb;37(1):20-7).
