Novartis Pharmaceuticals Corp v. West-Ward Pharmaceuticals International, Ltd.
The Novartis 131 patent claims methods of using the compound everolimus to treat advanced renal cell carcinoma (RCC). Advanced RCC is a cancer of the kidneys that has spread to other parts of the body. Everolimus is the active ingredient in Novartis’s Afinitor product. West-Ward’s predecessor filed an Abbreviated New Drug Application (ANDA) seeking to manufacture and sell generic versions of Afinitor. Novartis filed an infringement suit in response. The district court ruled that West-Ward failed to prove by clear and convincing evidence that claims 1–3 of the 131 patent are invalid as obvious in light of prior art, 35 U.S.C. 103(a). The Federal Circuit affirmed. While the district court erred in its analysis of whether there was a motivation to combine, a person of ordinary skill would not have reasonably expected success in using everolimus to treat advanced RCC as of February 2001.
