Eli Lilly Sues Sandoz for Infringement of Pharmaceutical Patent

Indianapolis, Indiana – Patent attorneys for Eli Lilly and Company of Indianapolis, IN, have initiated litigation alleging Sandoz, Inc. of Princeton, NJ, is infringing Patent No. 5,464,826, as issued by the U.S. Patent Officeand titled METHOD OF TREATING TUMORS IN MAMMALS WITH 2′,2′-DIFLUORONUCLEOSIDES.

The ‘826 patent covers the drug marketed under the name GEMZAR(R) for the treatment of abnormal masses of tissue known as neoplasms. The complaint states that, in a separate lawsuit, the ‘826 patent was found invalid on grounds of obviousness-type double patenting, but that Lilly has appealed to the Federal Circuit and believes the ruling will be reversed. Lilly also holds approved New Drug Application No. 20-509 for the use of GEMZAR(R) as a treatment for certain types of cancer.


The defendant allegedly filed a New Drug Application in the hopes of marketing a generic version of GEMZAR(R) before the expiration date of the ‘826 patent. Accordingly, in this case, Lilly requests that the court declare the ‘826 patent is valid and enforceable and that the defendant’s threatened acts would infringe the patent.

This case has been assigned to Judge Jane E. Magnus-Stinson and Magistrate Judge Tim A. Baker in the Southern District of Indiana, and assigned case no. 1:10-cv-01057-JMS-TAB.

Practice Tip: In the United States, because an application to protect a pharmaceutical via a utility patent is filed before clinical trials begin, the effective life of a drug patent is often considerably less than the patent term, which is twenty years from the application date. However terms for pharmaceutical patents may be extended to account for delays in obtaining FDA approval.
