Eight patents on HIV/AIDS medicines are being challenged by the Public Patent Foundation (PUBPAT), a US-based nonprofit legal service group working to “protect the public from the harms caused by errors within the patent system, particularly the harms caused by undeserved patents and unsound patent policy,” the group has announced.
The patents, held by US-based Abbott Laboratories, relate the antiretroviral drug ritonavir, brand name Norvir. PUBPAT says that prior art should have prevented the patents from being granted. If they are revoked, ritonavir will be able to be marketed and distributed by other drug companies in the United States.
The challenged patents are: U.S. Patents Nos. 5,541,206, 5,635,523, 5,648,497, 5,674,882, 6,037,157, 6,703,403, 7,148,359, and 7,364,752 and were approved on 10 February 2010, PUBPAT’s release said.
