U.S. Patent Office Rejects Key HIV/AIDS Drug Patents at PUBPAT Request: Government Finds Prior Art Submitted By PUBPAT Invalidates All of Gilead Scienc...(patents to either berevoked or changed m...),Health

"We are extremely pleased that the Patent Office has agreed with us that Gilead's TDF patents are invalid," said Ravicher. "This means that we are now well on the way towards ending the harm being caused to the public by Gilead's use of the patents to prevent anyone else from offering TDF to HIV/AIDS patients in the United States."

The Gilead Sciences TDF patents challenged by PUBPAT that have now been rejected by the Patent Office are U.S. Patents No. 5,922,695, 5,935,946, 5,977,089 and 6,043,230. Gilead has applied for similar patents on TDF in other countries throughout the world, including India, where they have received fierce opposition by non-profit AIDS patient groups.

More information about the reexaminations of the four Gilead Sciences TDF patents challenged by PUBPAT, including copies of the official Office Actions issued by the Patent Office rejecting all of the claims of each of the four patents, can be found at http://www.pubpat.org/gileadhivaidsdrug.htm.
