Geron Supports WARF´s Claims to Human Embryonic Stem Cell Patents
MENLO PARK, Calif., Apr. 2, 2007 – 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).
It is routine for the USPTO to grant patent re–examination requests. Furthermore, it is common for the USPTO to issue preliminary rulings that reject patent claims, only for the USPTO to terminate re–examinations and uphold patent claims in later stages of the review and appeals process.
As the world leader in the development of human embryonic stem cell–based therapeutics, Geron holds a broad portfolio of intellectual property rights. This portfolio includes the WARF patents in re–examination, additional WARF patents that are not subject to the re–examination proceedings and patents exclusively licensed from the University of California and the University of Oxford. In addition, Geron’s portfolio includes patents and patent applications filed by Geron covering technologies developed internally by Geron scientists for the production and differentiation of human embryonic stem cells.
Geron is developing first–in–class biopharmaceuticals for the treatment of cancer and degenerative diseases, including spinal cord injury, heart failure, diabetes and HIV/AIDS. The company is advancing an anti–cancer drug and a cancer vaccine that target the enzyme telomerase through multiple clinical trials. Geron is also the world leader in the development of human embryonic stem cell–based therapeutics, with its spinal cord injury treatment anticipated to be the first product to enter clinical development.
