February 8, 2012 - Completed National patent application filings of foundational lead patent application (Canadian Patent No 2735739). These filings apply to the United States, Mexico, Brazil, China, Japan, Korea, Singapore, the 37 countries of the European Patent Organization (EU), Great Britain, India and Australia.
Nov 22, 2011 - Granted foundational lead patent application, Canadian Patent No. 2735739 - Healthcare Facility Disinfection Process and System with Oxygen/Ozone.
September 15, 2011 - Filing of Insect Infestation Control application.
September 23, 2010 - Medizone International, Inc. filed a fourth U.S. Provisional patent application involving what it terms, “Advanced Oxidative Sterilization Processes.”
September 16, 2010 - Medizone International, Inc. filed a US Provisional patent application covering the use of AsepticSure for disinfecting sports equipment and training facilities.
September 14, 2010 - Medizone International, Inc filed a U.S. Provisional patent application covering the use of AsepticSure in food processing plants and related facilities for the sterilization of food-borne pathogens such as Listeria, Salmonella and other human harmful, food poisoning-causing bacteria.
September 9, 2010 - Medizone International, Inc. filed an additional international patent application covering recent developments in its variant of AsepticSure designed for government use in bio-terrorism countermeasures. The application, filed under the Patent Co-operation Treaty, extends coverage to over 120 countries, including all major industrialized countries for this government variant of the AsepticSure sterilization system.
July 7, 2010, - Medizone International, Inc. filed an international patent application under the auspices of the Patent Co-operation Treaty (PCT) to secure international patent protection for its Asepticsure technology.
The international patent application consolidates the two previously filed patent applications titled “Healthcare Facility Disinfecting System” and “Disinfecting Process and Apparatus.” It brings up-to-date and expands the technical evidence, both laboratory scale and practical scale, supporting the effectiveness of the technology in clearing healthcare and other critical infrastructure of bacterial infections such as C. difficile, MRSA, E coli, Pseudomonas aeruginous and VRE down to complete sterilization standard.
After the international patent application has been searched and examined by the International Patent Office authorities, Medizone can register it in any or all countries of the world that have ratified the PCT (of which there are over 140 such countries, which includes all major industrialized countries), and secure grant of patents on the application in countries of its choice.
January 20, 2010 - Medizone International, Inc. filed a second patent application was filed in combination with its previous patent application for AsepticSure filed in July of 2009. This patent application affords the Company greatly enhanced protection for both the hospital version of AsepticSure and the government variant intended for bio-terrorism countermeasures.
The integration of several complimentary technologies, each with their own antimicrobial effects, which in combination were shown not to be additive, but multiplicative motivated this filing.
Third Round Testing Delivered Unprecedented Kill Rates
Medizone International announced unprecedented success in being able to predictably achieve 6 log (99.9999%) kill rates for the causative agents of Hospital Acquired Infections (HAIs) represented with AsepticSure.
All samples tested during the third round of trials were either completely destroyed, that is no growth compared to the control samples, or so significantly reduced that the effect met the 6 log definition for sterilization.
The actual results of this series of tests indicate reductions in pathogens, commonly associated with HAIs, can reliably be achieved by AsepticSure as follows:
> 6.5 log for C difficile
> 7 log for MRSA
7 log for E-coli
6.6 log for VRE
7 log for Pseudomonas aeruginous
> 7 log for Bacillus subtilis
The sterilization of contaminated hospital spaces with a fully portable unit is now within reach without enormous expense, which will translate into greatly reduced suffering, thousands of lives saved and a dramatic cost benefit for the health care system globally.
July 2009 Patent Application
During July 2009, the Company filed a patent application for the AsepticSure technology in order to establish protection of its commercial rights to this technology internationally. The patent covers disinfection for rooms and their contents within all healthcare facilities, mobile or stationary, and other critical infrastructure such as schools and government buildings.
Medizone had two different firms specializing in patent law independently research the existing art in this area for a clear understanding on how to proceed from the beginning.
This patent filing not only identifies a number of unique technologies and their protocols, it provides the scientific data proving our ability to obtain 4.4 log/99.994% to 5 log/99.999% kill rates for all of the pathogens of concern in hospital acquired infections.
Original Application for Registration of Trademark
An application for registration of a trademark has been filed for the system with the United States Patent and Trademark Office for the mark AsepticSure™. The mark is used to describe a portable decontamination and sterilization system for hospitals, government buildings, schools and other functionally critical environments that might currently require, or need to be prepared for countermeasures capability from contamination by infectious biological agents such as C difficile, E coli, Pseudomonas aeruginous, MRSA and VRE (Vanocomycin-resistant Enterococci) another drug-resistant bacteria.
