CMI Invention Disclosures

Success for the Critical Materials Institute will be defined by how well it meets its mission to assure supply chains of materials critical to clean energy technologies. To enable innovation in U.S. manufacturing and to enhance U.S. energy security, CMI must develop, demonstrate, and deploy clean energy technology. To direct research in a way to minimize the time to discovery and the time between discovery and deployment, the CMI team includes both research and industrial partners.

One measure of progress is invention disclosures, which highlight areas where research may lead to a patent and licensing of a technology or progress.  CMI researchers have created many invention disclosures and filed dozens of patent applications, with four patents issued. CMI partners have issued four licenses covering eight technologies; one of these is an exclusive license.

Per the executed CMI Intellectual Property Management Plan, CMI Team Members have the first right of refusal to CMI Award Intellectual Property. Except for the exclusive license, the invention disclosures listed are CMI Award Intellectual Property that is available for licensing outside of the Team Members. Contact Stacy Joiner at the Ames Laboratory for information on how to license any of the listed CMI inventions or how to become a CMI TEAM Member for earlier notice of CMI inventions: 515-294-5932 or CMIaffiliates@ameslab.gov.

Technologies available for licensing can also be found online at the U.S. Department of Energy EERE Energy Innovation Portal. The Ames Laboratory provides additional information on Technology Transfer.
