Invisible Sentinel Announces Issuance of Second U.S. Patent Application for Rapid Diagnostic Technology to Detect Harmful Pathogens in Food

Invisible Sentinel Expands Intellectual Property for Company’s Diagnostic Technology

Philadelphia, Pennsylvania, May 22, 2012 - Invisible Sentinel Inc., a life sciences company that develops rapid diagnostics for the detection of foodborne pathogens, announced today it has been issued a second U.S. Patent, No. 8,183,059, entitled, “Device for Detection of Target Molecules and Uses Thereof.” This patent provides further protection for Invisible Sentinel’s proprietary diagnostic device capable of rapid and selective identification of pathogenic bacteria from contaminated food samples. The Company also has additional patent applications pending both in the United States and abroad.

“We are proud to announce the issuance of a second U.S. patent that protects our diagnostic devices and it marks yet another important milestone in the growth of our intellectual property portfolio,” said Benjamin Pascal, CEO and co-founder of Invisible Sentinel. “The company is currently pursuing regulatory approval of its patented and patent pending diagnostic devices and we are looking forward to commercializing our technology later this year.”

Invisible Sentinel’s diagnostic system provides a robust, sensitive, reproducible, and easy-to-interpret assay. The Company’s internally developed technology is designed to address the growing need for rapid, practical, and cost-efficient detection methods for foodborne pathogens at the point of care. The food industry is the first market that the Company is targeting, but its patented and patent pending technology has the potential to provide valuable tools for additional industries including healthcare, veterinary, biodefense, and environmental testing, where rapid detection of target analytes from unrefined samples is critical.
