:MAXM) today announced that the United States Patent and Trademark Office The United States Patent and Trademark Office (PTO or USPTO) is an agency in the United States Department of Commerce that provides patent protection to inventors and businesses for their inventions, and trademark registration for product and intellectual property  has issued a key patent supporting the company's MaxDerm(TM) technology for the treatment of topical maladies such as oral mucositis and herpes.

The patent, U.S. Patent Number 6,080,395, is entitled "Method and Composition for Topical Treatment of Damaged Tissue Using Histamine as Active Ingredient." This patent encompasses a pharmaceutical formulation underlying the company's MaxDerm technology, as well as the use of that formulation in the treatment of topical maladies such as oral mucositis, herpes labialis herpes labialis (hur´pēz lā´bēal´is),

Moderate exposure to ultraviolet radiation is followed by a red blush, but severe exposure may result in blisters, pain, and constitutional symptoms. , decubitus ulcers and shingles.

"Our research has suggested that MaxDerm's active agent, histamine, is an important molecule in the healing process for certain topical maladies, and we are pleased with the additional protection provided by this most recent patent," said Dr. Kurt Gehlsen, Maxim's senior vice president, development and chief technical officer. "Our preclinical work, and the results of pilot human studies, have shown promise in a number of indications, including oral mucositis and oral herpes. We are currently undertaking activities associated with the preparation of this drug candidate for human studies in oral mucositis."

Maxim now owns or has the rights to six issued U.S. patents and one U.S. patent application relating to MaxDerm. Corresponding international patents or patent applications have been issued or are pending.

Such statements are only predictions and the Company's actual results may differ materially from those anticipated in these forward-looking statements. Factors that may cause such differences include the risk that products that appeared promising in early research and clinical trials do not demonstrate safety or efficacy in larger-scale clinical trials, the risk that the Company will not obtain approval to market its products, the risk that clinical trials may not commence when planned, and the risk that if we fail to secure adequate protection of our intellectual property our products and technologies may not provide us with any competitive advantage. These factors and others are more fully discussed in the Company's periodic reports and other filings with the Securities and Exchange Commission.
