Fitzpatrick Cella Wins Appeal on Behalf of Merck & Co. in Trusopt Patent-Infringement Case

NEW YORK, April 2, 2007 – Leading intellectual property law firm Fitzpatrick, Cella, Harper & Scinto announced that it won an appeal on behalf of client Merck against generic patent challenges by Hi-Tech Pharmacal Co. in a case involving glaucoma eye drug Trusopt® (dorzolamide HCl opthalmic solution).

 

The U.S. Court of Appeals for the Federal Circuit held that a patent term extension under 35 U.S.C. §156 may be applied to a patent that is subject to a terminal disclaimer.  Hi-Tech had argued that Merck's patent on Trusopt® expired in 2004 because a patent term extension on the patent was invalid.

 

A Merck loss would have had drastic effects on pharmaceutical companies and patent owners, since the Patent Office has routinely granted patent term extensions on patents that are subject to a terminal disclaimer.  Brand-name drug companies could have lost years of patent protection on some of their best-selling drugs if the Federal Circuit had decided that a terminal disclaimer precludes a patent term extension 

Fitzpatrick, Cella attorneys representing Merck are Robert Baechtold and Paul Maier. The case was appealed from U.S. District Court for the District of New Jersey.
