Wisconsin Loses Round in Stem Cell Patent Battle
The U.S. Patent and Trademark Office ruled Wednesday in favor of the two consumer groups that challenged one of the patents held by the Wisconsin Alumni Research Foundation. Two other patents, which also cover discoveries made by UW-Madison scientist James Thomson, were not challenged and are not affected by the decision. Consumer Watchdog in Santa Monica, Calif., and the Public Patent Foundation in New York City argued that Thomson's work should not qualify for patents and that patent enforcement has hindered U.S. stem cell research.
