Ritonavir HIV/AIDS Drug Patents

In August 2010, PUBPAT filed formal requests with the United States Patent and Trademark Office challenging the eight patents held by Abbott Laboratories (NYSE: ABT) listed in the FDA's Orange Book for the key HIV/AIDS drug ritonavir (marketed by Abbott under the brand name Norvir). As part of its requests, PUBPAT submitted prior art that the Patent Office did not review before granting the patents to the Chicago, Illinois based pharmaceutical giant. PUBPAT also explained how the submitted prior art invalidates the patents and, as such, asked that the Patent Office undertake a review of all eight patents and revoke them.
