The U.S. Small Business Administration (SBA) is amending its Small Business Technology Transfer (STTR) Program Policy Directive in response to public comments SBA received on the final STTR and Small Business Innovation Research (SBIR) Policy Directives, published on August 6, 2012. SBA is also making several minor clarifying changes to ensure that the STTR participants clearly understand certain program requirements. Additionally, the changes to the STTR Policy Directive are made to maintain concordance with the SBIR program.
