The SBIR program exists in three phases. The purpose of Phase I is to prove the scientific or technical feasibility of the proposed research and development effort. Phase I projects typically are for 8 months. Phase II is the principal research and development effort and often involves moving the project from the laboratory to the field or the development of prototypes. Phase II projects typically are for 24 months. Phase III is the commercialization phase and there is no SBIR support provided for this phase. Phase I applications are due on September 3, 2009. This SBIR program funding opportunity is for Phase I applications.
