SINTX Technologies Expands Patent Protections for Antipathogenic Fabrics, Strengthening Biomedical IP Portfolio

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) 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.
