The Patent Trial and Appeal Board (the “Board”) issued a final written decision in an inter partes review determining Claims 1-5 of U.S. Patent No. 8,889,135 owned by Abbvie Biotechnology Ltd. unpatentable as obvious. Those claims cover methods of treating rheumatoid arthritis by administering—once every 13-15 days (i.e., biweekly) for a time period sufficient to treat the rheumatoid arthritis—40 mg of an antibody having certain sequences. The antibody D2E7, the active ingredient in Humira, is an antibody used in such a dosing regimen. The Board concluded that the challenged claims would have been obvious in light of two prior art references – van de Putte 2000 and Rau 2000 – which each described the results of clinical trials using D2E7.
