MENLO PARK, Calif.--(BUSINESS WIRE)--Geron Corporation (Nasdaq:GERN) supports the position of the Wisconsin Alumni Research Foundation (WARF) that U.S. patents covering Dr. James Thomson’s pioneering work with human embryonic stem cells were properly granted. Thomson’s success in isolating human embryonic stem cells is recognized by the scientific community as a significant breakthrough, and the scope of the patents granted to WARF is commensurate with that achievement. Three patents issued to WARF based on Dr. Thomson’s research are being re-examined by the U.S. Patent and Trademark Office (USPTO).
