Madison, Wis. – Claiming that patents and publications used to uphold a challenge to its stem cell patents are irrelevant to the isolation and proliferation of human embryonic stem cells, the Wisconsin Alumni Research Foundation has filed a response refuting an initial determination by the U.S. Patent and Trademark Office.
Those observations on relevancy, made by Carl Gulbrandsen, managing director of WARF, were supported by Dr. Colin Stewart, a stem cell researcher at the Institute of Medical Biology in Singapore.
