  12. Triggers for Conducting a SearchDiscovery and Development • Early stage landscape analysis • Overview of patentability and FTO issues • Competitor assessment • Patent drafting • Patentability analysis • Development decision points • Freedom-to-operate analysis • Competitor assessment ©2006 Millennium Pharmaceuticals, Inc.

  13. Triggers for Conducting a SearchBusiness Development • Identification of business opportunities • Competitive intelligence • Due diligence • Patentability • Freedom-to-operate ©2006 Millennium Pharmaceuticals, Inc.
