Company continues to advance its placental-derived product portfolio with the first patent granted in the fenestrated wound care market

POMPANO BEACH, Fla., Nov. 25, 2024 – PRISM MediaWire – BioStem Technologies, Inc.  (OTC: BSEM), a leading MedTech company focused on the development, manufacturing, and commercialization of placental-derived products for advanced wound care, today announced that the United States Patent and Trademark Office (USPTO) has issued a Notice of Allowance for Biostem’s patent application No. 18/591,883 for STERILE HUMAN PLACENTAL ALLOGRAFTS HAVING A PLURALITY OF SLITS, OPENINGS, AND/OR FENESTRATIONS FORMED THEREON. The patent application will grant as U.S. Patent No. 12,144,831 on November 19, 2024.

This patent will be used in the development of novel placental allografts designed for advanced wound care using BioStem’s BioREtain® process, which preserves essential natural factors. The allografts using this technology will feature flaps that open to allow exudate to escape without sacrificing surface area, making them suitable for both acute and chronic wound settings. This technology is unique, as there are no other fenestrated allografts on the market that offer the same benefits.

“BioStem continues to drive innovation in the wound care space, and we are pleased to enhance our intellectual property portfolio with the issuance of this significant patent. This is the first and only patent granted for use in tabular fenestrated allografts, which will support our commercial efforts and expands our IP portfolio. With 27 patents pending and 42 issued, BioStem has a strong portfolio across the wound care landscape that will protect the company as we advance in the market.”

A product using this technology is under development and is currently not commercially available and will be introduced using the HCT/P regulatory pathway. Once developed, the new allografts could be used as a protective covering for exudating wounds across the acute or chronic setting.
