Teva Pharm. Indus., Ltd. v. Astrazeneca Pharm., LP, No. 11-1091 (Fed. Cir. 2011)
Annotate this CasePlaintiff's 502 patent for a statin drug is a reissue of a patent that claims the benefit of a provisional application filed on April 10, 2000. The earliest date by which plaintiff asserts that it conceived and reduced to practice its claimed invention is December 1, 1999. In 2008 plaintiff sued for infringement by the drug Crestor. The district court found the 502 claims invalid, based on defendant's showing that it had conceived and reduced its drug to practice prior to plaintiff's first conception of the claimed subject matter (35 U.S.C. § 102(g)(2)). The Federal Circuit affirmed.
