Lightbridge Receives Notice of Allowance on New Patent from the Eurasian Patent Office

RESTON, Va., Nov. 03, 2025 (GLOBE NEWSWIRE) -- Lightbridge Corporation (“Lightbridge” or the “Company”) (Nasdaq: LTBR), an advanced nuclear fuel technology company, today announced that it has received a Notice of Allowance from the Eurasian Patent Office for its innovative multi-zone nuclear fuel rod design. Specifically, this patent covers methods and apparatus for fabricating fuel rods using additive manufacturing techniques, enabling the creation of distinct radial and axial zones with varying compositions of refractory metals and alloys, as well as fuel materials, such as zirconium alloys combined with uranium, plutonium, or thorium. The allowed claims, stemming from PCT application WO2023034173A1, which was filed in August 2022, describe a multi-zone fuel element structure where material properties and thicknesses vary along the axial or radial direction, thereby optimizing performance in nuclear reactors. Seth Grae, President and Chief Executive Officer of Lightbridge Corporation, commented, “This Notice of Allowance strengthens our intellectual property portfolio in Eurasia, a key region for nuclear energy deployment, home to over 40 operating reactors and ambitious expansion plans. Our patented additive manufacturing approach for multi-zone fuel rods represents a key innovation in producing next-generation Lightbridge Fuel™ rods, which can improve reactor economics, safety, and fuel utilization in both existing light-water reactors and emerging SMRs.” About Lightbridge Corporation Lightbridge Corporation (NASDAQ: LTBR) is focused on developing advanced nuclear fuel technology essential for delivering abundant, zero-emission, clean energy and providing energy security to the world. The Company is developing Lightbridge Fuel™, a proprietary next-generation nuclear fuel technology for existing light water reactors and pressurized heavy water reactors, significantly enhancing reactor safety, economics, and proliferation resistance. The Company is also developing Lightbridge Fuel for new small modular reactors (SMRs) to bring the same benefits plus load-following with renewables on a zero-carbon electric grid. Lightbridge has entered into two long-term framework agreements with Battelle Energy Alliance LLC, the United States Department of Energy’s operating contractor for Idaho National Laboratory, the United States' lead nuclear energy research and development laboratory. DOE’s Gateway for Accelerated Innovation in Nuclear program has twice awarded Lightbridge to support the development of Lightbridge Fuel over the past several years. Lightbridge is participating in two university-led studies through the DOE Nuclear Energy University Program at Massachusetts Institute of Technology and Texas A&M University. An extensive worldwide patent portfolio backs Lightbridge’s innovative fuel technology. Lightbridge is included in the Russell 2000® Index and the Russell 3000® Index.
