SETTLEMENT STATUS
None — MDL dismissed on Daubert
📋 Case Overview

The federal MDL alleging prenatal acetaminophen use causes autism and ADHD in children was dismissed in September 2023 after Judge Denise Cote excluded all plaintiffs’ general causation experts under Daubert. Without general causation, all cases fail as a matter of law. Some state court cases survive but face significant headwinds. This is effectively a dead mass tort at the federal level.

⚗ CAUSATION SUMMARY

The Daubert ruling found plaintiffs’ causation experts were unreliable. The science on acetaminophen and autism/ADHD is disputed — observational studies show correlation but multiple confounders exist. After MDL dismissal, this tort is not recommended for new campaigns.

⚖️ Litigation Status CLOSED — FEDERAL MDL DISMISSED

MDL 3043 — DISMISSED (S.D. New York)
Active Plaintiffs
N/A — MDL dismissed

MDL 3043 was dismissed in September 2023 after Judge Denise Cote excluded all plaintiffs' general causation experts under Daubert. Without general causation, all federal cases failed. Some state court actions survive but face the same causation headwind.

Key Verdicts & Settlements
❌
MDL dismissed on Daubert — September 2023
Judge Cote excluded all plaintiff causation experts. Catastrophic loss for the MDL. Federal claims are effectively over.
⚠️
State court cases survive — for now
Some state court cases proceed under different evidentiary standards, but face the same causation science challenges.
📉
Filing trend: Closed. Federal MDL is dead. Do not take new federal Tylenol-autism cases. State court campaigns are extremely high risk given the Daubert outcome.

Jacob Score™ — Methodology & Legal Disclaimers
The Jacob Score is a composite 1–100 litigation opportunity index for mass torts, produced by the TortIntel editorial team at Mass Tort Ad Agency. It is updated periodically as litigation conditions change.

Score Dimensions (each rated 1–5)

Science — Peer-reviewed study quality and quantity, relative risk magnitude, replication across independent research groups, FDA or regulatory action taken, and estimated Daubert survivability based on published expert testimony and prior rulings.

Momentum — MDL formation and phase, plaintiff count trajectory, case consolidation activity, and overall litigation velocity.

Campaign — Current filing window status, case saturation, defendant solvency, estimated qualifying population size, and co-defendant dynamics.

Timeline — Proximity to first expected resolution or bellwether trial, current discovery or Daubert phase, and estimated time-to-value for a signed plaintiff.

Verdicts — Confirmed plaintiff jury verdicts, bellwether trial win/loss record, and size or certainty of any established settlement fund. 1 = pre-trial · 2 = mixed early results · 3 = partial settlements or initial wins · 4 = confirmed large verdicts or funded settlement · 5 = landmark verdicts with formal settlement program.

LEGAL DISCLAIMERS

The Jacob Score and all associated content on TortIntel.ai is provided solely for mass tort business intelligence and law firm marketing decision-making purposes. It does not constitute legal advice, litigation strategy advice, or a recommendation to file or refrain from filing any lawsuit.

The Jacob Score is an editorial opinion based on publicly available data including court filings, published scientific literature, regulatory actions, and reported settlement information. It is not a guarantee of future litigation outcomes. Past verdicts and settlements are not predictive of future results in any specific case.

TortIntel.ai and Mass Tort Ad Agency make no representation that any score is complete, accurate, or current. Litigation conditions change rapidly. Attorneys must conduct independent due diligence and consult qualified co-counsel before making any case acquisition or litigation funding decisions based on this or any other intelligence tool.

This score must not be used to evaluate, accept, or reject any individual plaintiff’s case. Case-specific merit depends on individual facts, applicable state law, expert medical and scientific analysis, and jurisdiction-specific statutes of limitations — all of which are beyond the scope of this tool.
