SINTX Technologies, Inc. (NASDAQ:SINT) ("SINTX" or the "Company"), an advanced ceramics innovator specializing in biomedical applications of silicon nitride (Si₃N₄), today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for a patent application containing method claims covering the Company's antipathogenic fabric technology.
This development builds upon SINTX's previously announced patent allowance for its Antipathogenic Fibrous Materials composition patent, expanding the Company's Intellectual Property (IP) to protect both the material itself and the processes that bring it to market. This dual coverage strengthens the Company's competitive advantage, enhances licensing and partnership opportunities, and broadens potential applications across medical textiles, filtration media, and other infection-prone surfaces.
These two patent families create a comprehensive IP competitive barrier around SINTX's surface-level pathogen-inactivation technology, covering applications in wound dressings, surgical drapes and gowns, filtration media, personal protective equipment (PPE), and high-touch clinical surfaces.
"We are excited to announce the allowance of our Method Patent for Antipathogenic Fibrous Materials, marking a significant milestone that strengthens and broadens the protection of our proprietary silicon nitride technology platform." said Eric K. Olson, Chairman and CEO of SINTX Technologies. "This newly allowed patent complements the recently issued U.S. Patent No. 12,433,356, granted on October 7, 2025, which covers the composition of silicon nitride for antipathogenic fibrous materials. Together, these patents reinforce SINTX's leadership in infection-resistant material innovation and expand the Company's IP protection to cover both the composition of its fabrics and methods by which they are produced and applied. We believe this dual-layer IP foundation significantly enhances the licensing and commercialization potential of our platform."
Lisa Marie, Del Re, Chief Commercial Officer, added, "With method claims, we can now defend and license the manufacturing and application pathways that unlock silicon nitride's antipathogenic performance in textiles and surfaces. This is crucial as we engage with potential wound-care, filtration, and medical-textile partners."
