WARF Stem Cell Patents

In July 2006, PUBPAT filed formal requests with the United States Patent and Trademark Office on behalf of the Foundation for Taxpayer and Consumer Rights, now known as Consumer Watchdog, to revoke three patents owned by the Wisconsin Alumni Research Foundation that purport to cover stem cells that are looting taxpayer funds and forcing research overseas. In its filings, PUBPAT submitted previously unseen prior art showing that the patents were - in fact - not new and, as such, should be revoked. The USPTO granted each of the requests in September 2006 and rejected all claims of each of the patents on March 30, 2007. The patent holder later amended its claims to narrow them over the original ones and the Patent Office then, incorrectly, decided to reissue those amended claims. In the one challenge where Consumer Watchdog had the right to appeal the Patent Office's erroneous decision to the Court of Appeals for the Federal Circuit, it did so in 2013.
