American Terbium has filed eight provisional patent applications with the United States Patent and Trademark Office, marking an important step in the company’s effort to strengthen domestic heavy rare earth supply. The applications relate to technologies and processes focused on recovering critical materials such as dysprosium, terbium, and yttrium. These metals are essential for next-generation defense systems, autonomous platforms, clean energy technologies, and advanced industrial applications. Today, the United States remains heavily dependent on imports for these elements, creating a strategic vulnerability for both national security and high-tech manufacturing. American Terbium’s approach focuses on recovering rare earth elements from already-mined tailings and waste rock rather than relying on conventional hard-rock mining. This model could shorten development timelines, reduce initial capital needs, and support remediation of legacy mining materials. The patent filings reflect the company’s broader strategy to build a faster and more secure domestic rare earth supply chain. By advancing modular direct-leach technology and targeting high-value heavy rare earths, American Terbium aims to help close a critical gap in U.S. mineral independence. ›
