Lightbridge received a Notice of Allowance for its U.S. Patent Application No. 18/383,668, covering a spirally twisted, multi‑lobed fuel element design for pressurized heavy‑water reactors, including CANDU plants. The allowance covers 16 claims and also includes a reactor incorporating the assembly.
The patent protects elongated fuel elements with a spirally twisted, multi‑lobed profile, each containing a fissile kernel in a metal matrix surrounded by cladding. The allowance extends Lightbridge’s IP into both fuel and reactor design, positioning the company to pursue licensing or manufacturing partnerships for its metallic fuel technology.
Lightbridge’s metallic fuel technology offers higher thermal conductivity and power density than conventional ceramic fuel, potentially improving reactor safety, economics, and proliferation resistance. The allowance strengthens the company’s portfolio in the United States, Canada, and other key jurisdictions, and supports its strategy to commercialize fuel for heavy‑water reactors and small modular reactors.
CEO Seth Grae emphasized the strategic importance of the patent, stating: "This Notice of Allowance further strengthens our U.S. intellectual property portfolio, particularly for our multi‑lobed fuel element design optimized for pressurized heavy water reactors. The CANDU reactor fleet represents a significant global market opportunity, and this patent further reinforces our technology’s applicability to heavy‑water reactor designs. Our growing patent portfolio, spanning the United States, Canada, and other key jurisdictions worldwide, underscores the foundational and differentiated nature of Lightbridge Fuel™."
Investors responded positively to the announcement, reflecting confidence in Lightbridge’s expanded IP and its potential to capture a share of the global CANDU reactor market. The allowance is part of a broader strategy to build an extensive worldwide portfolio, with existing patents in Canada, Eurasia, Australia, Japan, South Korea, and the European Union.
Lightbridge’s market capitalization is $347 million, and the company has no debt and a high current ratio. The company faces challenges related to profitability and insider selling activity, but the new patent allowance positions it to pursue licensing or manufacturing partnerships and to strengthen its competitive position in the nuclear fuel market.
