Case: Patents/Obviousness (Fed. Cir.)

The Federal Circuit affirmed the decision of a federal district court in Virginia entering judgment in favor of the government on ImmunoGen Inc.'s patent application directed to a dosing regimen for administering a patented antibody drug conjugate used for treating certain ovarian and peritoneal cancers. The appeals court said that the district court didn’t clearly or legally err in holding that the claims of the application would have been obvious over prior art.
