SEATTLE, March 7 /PRNewswire-FirstCall/ --
ENBREL(R) (etanercept) has been on the market since 1998 and under
development for over ten years.
Over at least the past two years, ZymoGenetics has raised their patents
with Immunex, but has never charged Immunex with infringement, even though
Immunex has, on numerous occasions, requested that ZymoGenetics explain their
patent position.
Immunex believes ZymoGenetics' allegations are without merit and will
vigorously defend itself against this lawsuit.
Immunex Corporation is a biopharmaceutical company dedicated to improving
lives through immune system science innovations.
