ATLANTA, GA and WARSAW, POLAND--(Marketwired - August 27, 2014) - Perma-Fix Medical S.A. (WARSAW: PFM), a subsidiary of Perma-Fix Environmental Services, Inc. (NASDAQ: PESI), and developer of a reliable, cost effective, non-uranium process to produce technetium-99 (Tc-99m), the most widely used medical isotope in the world, today announced that in mid-August 2014, the US Patent Office issued a notice of allowance to Perma-Fix Environmental Services, Inc. allowing all claims in its recent patent application for preparation of its Microporous Composite Material and its derivatives. Perma-Fix Medical has a Patent License Agreement with Perma-Fix Environmental Services, for the production of Tc-99m.

Dr. Louis F. Centofanti, of Perma-Fix Medical, commented, "Issuance of this patent is a major milestone for the company. The U.S. Patent and Trademark Office has granted us protection for our intellectual property to produce Tc-99m. With this patent in hand, we look forward to advancing our cost-effective, non-uranium process, which we believe will reshape the global supply chain of Tc-99m."

The claim of the patent addresses the proprietary resin that Perma-Fix manufactures and includes:

  • Selective separation of Tc-99m pertechnetate from Mo-99
  • Enhanced sorption of Mo with a holding capacity in excess of 60% of the dry weight of the sorbent
  • Sorbent and generator resistant to degradation by gamma and beta radiation and acid environments
  • Sorption of selective isotopes from radioactive waste streams
  • Removal of heavy metals, such as mercury and arsenic, from waste water streams

About Perma-Fix Medical S.A.

Perma-Fix Medical was formed to develop, obtain FDA and other regulatory approval and commercialize a new process to produce Technetium-99 (Tc-99m), the most widely used medical isotope in the world. The new process is expected to solve worldwide shortages of Tc-99m as it is less expensive, does not require the use of government-subsidized, weapons-grade materials and can be easily deployed around the world using standard research and commercial reactors, thereby eliminating the need for special purpose reactors.
