Pegfilgrastim Challenged Claim Types in IPR and Litigation: Claims include those challenged in litigations and IPRs. Claims are counted in each litigation and IPR, so claims from the same patent challenged in multiple litigations/IPRs are counted more than once. Within each litigation a claim is counted only once. Within each IPR, claims are counted only once, whether they are challenged under § 102, § 103, or both. Claims in litigations are determined based on claims alleged to be infringed or invalid in Complaints.
