The patent covers fuel elements manufactured via additive manufacturing (3D printing), a process that enables the production of complex multi-material zone architectures that are unachievable through conventional fuel fabrication techniques. Combined with Lightbridge&#8217;s existing U.S. and international patent portfolio, this grant meaningfully expands the Company&#8217;s IP moat in advanced nuclear fuel.<\/p>\n<p align=\"justify\">The allowed claims are directed to a fuel element comprising three distinct radial zones of different materials \u2014 a first zone extending along the central axis, a second surrounding zone, and a third outermost zone \u2014 in which the thickness of both the second and third zones in the radial direction varies along the axial direction. The manufacturing method claims cover the use of additive manufacturing to produce this multi-zone architecture using metallic, ceramic, or cermet fuel systems. The variable zone thickness along the axial direction enables engineers to tailor the radial and axial neutron flux profile within a single element, supporting optimization of reactor performance, safety margin management, and fissile material efficiency throughout the fuel cycle.<\/p>\n<p align=\"justify\">\u201cReceiving this allowance from the European Patent Office is an important validation of the technical depth and novelty of Lightbridge Fuel\u2122,\u201d said Seth Grae, President and Chief Executive Officer of Lightbridge Corporation. \u201cEurope is home to a significant installed base of nuclear generating capacity, and the countries and utilities advancing nuclear energy as part of their clean energy programs represent a natural market for Lightbridge Fuel. This patent ensures that the fuel element design at the heart of Lightbridge Fuel, with our precise multi-zone architecture and variable radial zone configuration, is protected across those markets as we advance toward commercialization.\u201d<\/p>\n<p align=\"justify\">\n        <strong>About Lightbridge Corporation<\/strong>\u00a0<br \/>Lightbridge Corporation (NASDAQ: LTBR) is focused on developing advanced nuclear fuel technology essential to delivering abundant, zero-emission, clean energy and providing energy security to the world. The Company is developing Lightbridge Fuel\u2122, a proprietary next-generation nuclear fuel technology for existing light-water 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\u00a0to deliver the same benefits, plus load-following with renewables, on a zero-carbon electric grid.<\/p>\n<p align=\"justify\">Lightbridge has entered into two long-term framework agreements with Battelle Energy Alliance, LLC, the United States Department of Energy\u2019s operating contractor for Idaho National Laboratory, the United States\u2019 lead nuclear energy research and development laboratory. DOE\u2019s Gateway for Accelerated Innovation in Nuclear program has twice awarded Lightbridge to support the development of Lightbridge Fuel over the past several years. An extensive worldwide patent portfolio backs Lightbridge\u2019s innovative fuel technology. Lightbridge is included in the Russell 2000\u00ae and Russell 3000\u00ae Indexes.
