USPTO Grants Quick-Med Technologies 6th NIMBUS® Patent Covering PUR-modified Polycation

Published on 2012-01-12. Author : SpecialChem

GAINESVILLE, Fla. -- Quick-Med Technologies, Inc. (OTCQB:QMDT), a life sciences company that is developing innovative technologies for the healthcare and consumer markets, announced that it has been awarded a sixth U.S. patent for its novel, non-leaching NIMBUS® antimicrobial technology.

The U.S. Patent and Trademark Office has issued Quick-Med Technologies U.S. Patent No. 8,088,400 entitled "Disinfectant with Quaternary Ammonium Polymer and Copolymers." The new patent covers the Company's novel polyurethane-modified polycation, the newest member of the NIMBUS technology family of antimicrobials. NIMBUS technology encompasses the chemistry of antimicrobials that comprise a high charge density polycation which is built into the backbone of various polymers such as polyurethane in this case.

The newly granted patent is a key "composition-of-matter" patent that covers incorporation of a NIMBUS polycation into main chain of a urethane polymer. The physical state of the polyurethane polycation can be modified to alter the strength of the antimicrobial, the breathability of the film or coating and its flexibility or rigidity. The patent provides protection for various claims regarding the efficacy and durability of an antimicrobial polyurethane.

"This patent adds an exciting new dimension to our NIMBUS technology," says Dr. William Toreki, co-inventor and Quick-Med's Chief Chemist. "Our new polyurethane polycation is well suited for a wide range of applications including films and coatings, adhesives, catheters and other types of extruded tubing, and as a durable hand sanitizer."

"This sixth NIMBUS patent is strategically important because it significantly expands our proprietary NIMBUS technology," said Dr. Jerry Olderman, Quick-Med's vice president of Research & Development and a co-inventor. "It protects the underlying chemistry for several of our cutting-edge developments including applications for advanced wound dressings, medical adhesives, and catheters."

NIMBUS technology employs a safe, eco-friendly active agent that remains in full concentration on any of several substrates. It controls a broad range of both Gram-positive and Gram-negative bacteria. NIMBUS antimicrobials are not depleted in use, maintain effectiveness even in the presence of large amounts of blood or body fluids, and by design, pose no risk of bacteria developing resistance.

NIMBUS non-leaching antimicrobial technology was cleared by FDA in 2009 and is available in the BIOGUARD® barrier dressings from Derma Sciences, Inc. (Nasdaq:DSCI). NIMBUS is the only non-leaching antimicrobial wound dressing. NIMBUS technology is protected by ten U.S. patents and patents pending and 24 foreign counterparts.
