Regeneron Pharmaceuticals, Sanofi Win Court Ruling in Patent Case Against Amgen

5:11PM ET 8/28/2019 MT Newswires
Regeneron Pharmaceuticals (REGN) and Sanofi said that a federal court ruled that Amgen's (AMGN) patent claims were invalid in litigation against the drug makers.

Amgen's claims related to antibodies aimed at PCSK9, Regeneron and Sanofi said in a statement. PCSK9 is a gene that gives instructions for producing a protein that aids in regulating cholesterol, according to the US National Library of Medicine.

"Today's decision by the U.S. District Court for the District of Delaware validates our position that Amgen's patents are overly broad and invalid," Joseph LaRosa, Regeneron's general counsel said in a statement.
