North Charleston, South Carolina – March 9, 2005 – Argolyn Bioscience announced today the addition of a fifth issued patent to its growing intellectual property portfolio. U.S. Patent Number 6,858,396 titled “Positively charged non-natural amino acids, methods of making and using thereof in peptides” covers the structure and uses of another set of amino acid analogs invented by Dr. Thomas A. Dix and exclusively licensed to Argolyn Bioscience for the optimization of peptide-based pharmaceutical candidates.

“This patent completes the second series of compounds devised by Dr. Dix, and creates a sizeable footprint around the intellectual property that is key to Argolyn’s future growth,” said Pearce Gilbert, president of Argolyn Bioscience. “Foreign equivalents are still pending, but the success in prosecuting the US cases suggests a good probability that the foreign cases also will issue in due course.”
