SpectraScience is also the exclusive licensee through the Massachusetts General Hospital of U.S. Patent 5,843,000 entitled, “Optical Biopsy Forceps and Method of Diagnosing Tissue”. We believe that this patent, in combination with our other optical forceps patents, provides the Company an advantage in marketing biopsy forceps that contain optical fiber. The above patents expire between 2015 and 2022. Each of the international patents designates several countries for patent protection.

The Company believes that it holds one of the strongest patent portfolios of its kind in the field of optical methods for the diagnosis and detection of tissue abnormalities, particularly for identifying cancer and its precursors. Management also believes that its intellectual property portfolio will protect the core technology and methods embodied in the WavSTAT4 Optical Biopsy System as well as for many of the Company’s future products and can create a substantial barrier to entry for others pursuing similar approaches.
