Consumer groups file to have stem cell patents rescinded
<p class="source">Contra Costa Times (California)</p>
<p>On Tuesday, two consumer groups filed challenges with the U.S. Patent and Trademark Office seeking to have the patents rescinded. The groups maintain that the patents are overly broad and that previous work by other scientists made Thompson's breakthroughs obvious and unpatentable. "The debate in Washington is morally based, but what's at stake with the patents is essentially money," said John Simpson of the Foundation for Taxpayer and Consumer Rights, one of the groups that filed the challenge.</p>
