Further Expands NIMBUS' International Intellectual Property Protection

GAINESVILLE, FL -- (MARKETWIRE) -- 07/23/12 -- Quick-Med Technologies, Inc. (PINKSHEETS: QMDT) (OTCQB: QMDT), a life sciences company that is developing innovative technologies for the healthcare and consumer markets, announced today that the patent office of Mexico, Instituto Mexicano de la Propiedad Industrial (IMPI), has issued a new patent that expands the international intellectual property coverage of Quick-Med's NIMBUS® technology.

Mexico patent No. 297,242 is titled "Method of Attaching an Antimicrobial Cationic Polyelectrolyte to the Surface of a Substrate." It remains in effect until August 22, 2026. Similar patents have been granted in the United States, Australia, and South Africa and are pending in Canada, China, Europe, India, and Japan.

The new patent covers the method of production that non-leachably bonds NIMBUS antimicrobials to various treated substrates. It addresses the process of attaching members of the NIMBUS family of antimicrobials to substrates that are whole or in part cellulosic or any of a list of other substrates including such polymerics as polyurethane, polyester, nylon and acrylics, as well as silk, linen, rubber, alginates and collagen among many others. These are materials that are commonly used in textile and medical products, filters, absorbent products, and packaging.

"Our non-leachable bonding of the antimicrobial agent distinguishes NIMBUS from other antimicrobial materials which require release of the active agent in order to function," said Dr. Jerry Olderman, Quick-Med's vice president of Research & Development. "This patent covers the process of treating materials such that they become permanent barriers to the transmission of microorganisms."

While NIMBUS antimicrobials remain at full strength, the active agent in most other antimicrobial technologies is depleted gradually while in use. These other antimicrobials carry the risk of irritation or interference with healing in products such as wound dressings and textile applications in which the treated material is next to or used on the skin.

The bonding of an antimicrobial to a substrate is a paradigm shift from the current state-of-the-art which fosters release of the active agent. The value of a non-leaching antimicrobial is that it does not allow depletion of the active agent which can lead to damage to human skin or tissue cells such that they can cause irritation, delay healing and possibly initiate the development of bacterial resistance.

Quick-Med's patented technology, NIMBUS, is a cutting-edge antimicrobial technology that has been custom designed for wound care and other medical applications. NIMBUS received De Novo FDA clearance in 2009 and has been commercialized in traditional wound care applications. It is the only non-leaching antimicrobial dressing which, by design, poses no risk of bacteria developing resistance. NIMBUS technology is protected by twelve U.S. patents and patents pending and 24 foreign counterparts. Additional applications under development include advanced wound dressings, medical adhesives, catheters, and contact lenses.
