U.S. Rare Earth Magnet Patents Table
CMI reviewed the U.S. patent database to better understand what is known about rare earth magnets and to identify potential areas to explore. Based on this, CMI created a table of more than 460 recent U.S. patents that address rare earth magnet compositions and processes. The table is available as a searchable pdf document (updated August 29, 2016).
Information in the table includes:
- Patent number
- Dates of filing, issue and projected expiration
- Assignee name and country of origin
- Patent tile, abstract and illustrative claims
As noted in the Grand Challenges, the Critical Materials Institute works to reduce the time to discover and implement advanced materials for specific uses, and to close the gap on the timeframe on which materials criticality typically emerges.
Disclaimer: This U.S. Rare Earth Magnet Patents Table contains a sample of the rare-earth-magnet patents issued by the U.S. Patent and Trademark Office. It was created with key word searching. The Table is not all inclusive of US magnet patents and does not include foreign patents. Some cells in the Table contain estimates, approximations or assessments. Please consult with a professional patent attorney or patent agent, possessing license to represent clients before the United States Patent and Trademark Office, before proceeding from informal patent database searches to formal patent actions.
