Sun Pharmaceuticals, Inc. v. Eli Lilly, Co.
Sun Pharmaceutical Industries, Ltd.
In a case that garnered national press attention, Winston & Strawn defeated a patent covering one of Eli Lilly & Co.’s leading cancer drugs. On behalf of client Sun Pharmaceutical Industries, Winston asserted that Lilly engaged in improper double patenting to protect Gemzar®, a blockbuster drug with annual sales exceeding $2 billion per year. Both the district court and the Federal Circuit agreed with Winston and invalidated the offending patent, which will allow generic competition to Gemzar® two-and-a-half years early.
