ARIAD V LILLY, PART II: THE NEXT BIG PATENT BATTLE
The bell's about to sound for the next round in a patent fight that the entire pharmaceutical industry is watching. Next week the biotechnology firm Ariad Pharmaceuticals and the big drugmaker Eli Lilly & Co. head back to court in a fight over a patent that Ariad claims gives it rights to a drug pathway.
The pathway is the specific way a drug works in the human body. This is a highly
unusual case since patents tend to cover a drug's composition, not the way it
affects the body.
