NASA has released 56 formerly patented agency technologies into the public domain, making them technologies freely available for unrestricted commercial use. In addition to the release of these technologies, a searchable database is now available that catalogs thousands of expired NASA patents already in the public domain. The technologies were developed to advance NASA missions, but may have nonaerospace applications and be used by commercial space ventures and other companies. "By making these technologies available in the public domain, we are helping foster a new era of entrepreneurship that will again place America at the forefront of high-tech manufacturing and economic competitiveness," said Daniel Lockney, NASA's Technology Transfer program executive.
