Methodology & data sources

  • Drugs in class: aggregated from drug.pharmClassEpc field. Drugs without EPC tags are not included here (data gap, not coverage limitation).
  • Patent data: per-drug patent thickets from FDA Orange Book / Purple Book + BigQuery family expansion. See individual drug patent pages for source detail.
  • LOE waterfall: sorted by latestPatentExpiry from Orange Book. Reflects US patent term adjustments (PTA) but not exclusivity overlays (ODE, NPP, PED).
  • Class-level analysis: sums across per-drug thickets. Same patent family may appear in multiple drugs (e.g., Jakafi + Opzelura share composition family) — counted once per family per drug for OB totals.
Intelligence, not legal advice. Class-level summary reflects what's listed publicly. Generic launch dynamics depend on per-drug NCE/ODE/PED overlays, ANDA Para IV outcomes, and BPCIA settlements not captured here.
