This appeal concerned 10 inter partes reviews (IPRs) filed by petitioners Neptune Generics, Fresenius Kabi USA and Mylan Laboratories against all of the claims of U.S. Patent No. 7,772,209, which is owned by Eli Lilly & Co. The ’209 patent concerns methods of administering pemetrexed disodium, an antifolate chemotherapeutic agent, in combination with folic acid and a methylmalonic acid (MMA) lowering agent, such as vitamin B12. The co-administration of the folic acid and the MMA lowering agent was represented as reducing the toxicity of the antifolate chemotherapy.
