The case will proceed to trial Sept. 4, 2007 where the court will hear Amgen's claim of infringement for additional patents and also hear other Roche arguments on the validity and enforceability of Amgen's patents. Amgen continues to believe that its patents are valid and enforceable, and that Roche's peg-EPO product will infringe other Amgen patents relating to recombinant erythropoietin and its production.
In addition to infringing its EPO patents, Amgen firmly believes Roche's peg-EPO product provides no clinical or patient benefit over Amgen's innovative therapies, EPOGEN(R) (Epoetin alfa) and Aranesp(R) (darbepoetin alfa).
