Describe a drug candidate. Get a ranked list of blocking Orange Book patents + AI risk assessment — grounded in our 16,724 enriched patent database. Pro tier: 5 assessments / 24h.

Best results: include target, modality, and indication. e.g. "oral small molecule KRAS G12C inhibitor for NSCLC". Output is decision-support, NOT legal advice — get an outside-counsel opinion before acting.

FTO Risk Assessment

Top blocking patents

FTO ScorePatentDrugTypeVulnYears leftAssignee

How the FTO score works

For each candidate, we pull every Orange Book patent that potentially blocks (matches on target, competitor drug names, or assignee). Each patent gets a 0-100 FTO Risk score blending:

  • Blocking strength (50%) — derived from 100 − vulnerability_score. Patents that are hard to invalidate or design around block harder.
  • Relevance (30%) — keyword overlap with target / modality / drug names + drug-substance flag boost.
  • Runway (20%) — years to patent expiry, capped at 20 points.

Patents with FTO score ≥70 are high-risk blockers. Patents with vulnerability ≥70 (regardless of FTO score) are flagged as design-around / IPR opportunities.

Disclaimer: AI-generated FTO analysis is decision-support, not legal advice. Verify with patent counsel before committing R&D spend.
