When the patent for Zyprexa® and $2 billion in annual revenue were on the line, Eli Lilly turned to Finnegan

This ANDA case involved Zenith and two other generic drug manufacturers that attempted to invalidate Lilly's patent and thereby open the market for generic sales. The lengthy trial involved complex technical and legal issues. Lilly prevailed in the district court on all issues, protecting its exclusive marketing rights and a large revenue stream. The Federal Circuit later affirmed the lower court's decision, which upheld Lilly's patent on its blockbuster drug.
