MDL 2738 · Pharmaceutical & product liability
Federal claims alleging that talc products caused ovarian cancer or mesothelioma are coordinated in New Jersey.
Open the case trackerTalc litigation timeline
The federal talc docket has moved through centralization, expert-evidence rulings, three bankruptcy attempts, and a renewed Rule 702 review. This dated timeline separates those procedural events from state trials, settlements, and scientific findings.
Talc docket data
MDL 2738 grew from 58,205 pending federal actions in January 2025 to 68,435 in July 2026. The trend is real, but it does not measure state cases, validated claims, scientific strength, settlement value, or payment timing.
Talc settlement mechanics
Three corporate bankruptcy efforts sought a broad resolution of talc claims. None produced a confirmed global personal-injury plan. This guide separates those rejected proposals from state consumer settlements, individual resolutions, and the still-active federal MDL.
Evidence review
Case-control studies, prospective cohorts, laboratory evidence, and regulatory testing answer different questions. This review explains the signal, the uncertainty, and the gap between population research and an individual claim.
MDL 2846 · Medical device
Federal cases involving certain Bard and Davol polypropylene hernia mesh products are coordinated in Ohio.
Open the case trackerSettlement process guide
MDL 2846 has a qualified settlement fund and court-supervised administration, but its public orders do not publish a universal payout grid. Here is how the process fits together.
Bard docket data
Four verified JPML snapshots show a large federal docket moving from growth to gradual decline, but the count alone cannot identify who settled, who was dismissed, or what any claim may be worth.

Open the case trackerAFFF litigation chronology
A dated, source-led guide to MDL 2873, from federal centralization through water-system settlements and the still-developing personal-injury bellwether process. Status verified July 10, 2026.
AFFF claim types explained
The AFFF MDL contains public-water, personal-injury, property, and other claims. This guide explains why a utility settlement cannot be used as a payout forecast for an individual illness claim.
AFFF docket data
Verified federal snapshots reveal a docket reshaped by both new filings and resolved public-water claims, while personal-injury work continues on a separate procedural track.
MDL 3060 · Consumer product
Federal lawsuits concerning certain hair relaxer products and alleged cancer risks are coordinated in Illinois.
Open the case trackerHair relaxer timeline
Research on uterine and ovarian cancer triggered thousands of lawsuits, but the scientific studies and MDL orders answer different questions. This timeline tracks both without treating allegations as findings.
Hair relaxer evidence
Several prospective cohorts have reported associations involving uterine, ovarian, breast, and selected non-reproductive cancers. The results are not interchangeable, and none can identify the cause of one person's diagnosis on its own.
Docket data
MDL 3060 grew while thousands of actions also left the active inventory. These dated JPML figures show the scale without turning docket arithmetic into settlements or scientific conclusions.
MDL 2789 · Pharmaceutical
The federal PPI docket coordinates claims involving certain heartburn medicines and alleged kidney injuries.
Open the case trackerPPI litigation chronology
A careful chronology of the PPI kidney-injury litigation, from the studies that sharpened the warning debate to federal centralization, bellwether planning, and the July 2026 court inventory.

Open the case trackerBair Hugger chronology

Forced-air warming evidence
The infection question spans engineering, microbiology, orthopedics, and epidemiology. This guide explains what each evidence type contributes, and why no single study settles the question.
MDL 3004 · Chemical exposure

Open the case trackerParaquat litigation chronology
A source-checked chronology of MDL 3004, including the abandoned first bellwether program, plaintiff-screening orders, and the limited facts made public about a 2025 master settlement agreement.
Paraquat docket data
The official numbers show a docket that kept growing through a major expert ruling and a later settlement agreement covering certain claims rather than the whole docket.

Docket data
Verified JPML snapshots for MDL 3140, with a plain-English explanation of pending versus historical actions and why docket growth cannot predict outcomes.
Settlement status
The court has confirmed a global agreement for some pending MDL plaintiffs. Its terms are not public, it will not resolve every case, and expert litigation is continuing.
Evidence review
A careful reading of the French national study, later U.S. research, and the FDA label, keeping population associations distinct from any individual diagnosis or legal conclusion.
FDA label history
What FDA-approved labels from 2010, 2024 and 2025 actually say, and why a label change matters without being a court finding of liability.
Court order guide
MDL 3140's orders tell a more useful story than its raw case count. They show how the court tests product use, injury documentation, preemption, expert evidence, and a disclosed agreement that does not cover every case.
MDL 2974 · Medical device
Federal lawsuits alleging breakage or complications during removal of the Paragard IUD are coordinated in Georgia.
Open the case trackerParagard litigation chronology
A dated guide to the federal Paragard breakage litigation, from centralization in 2020 through case-specific limitation rulings and the latest public bellwether schedule reviewed.

MDL 2741 · Chemical exposure
The federal Roundup docket coordinates claims alleging that glyphosate exposure caused non-Hodgkin lymphoma.
Open the case trackerFederal and state litigation
Roundup litigation runs on two tracks. This guide separates MDL 2741 from state cases, explains what a bellwether can prove, and shows why nationwide case and payout claims are often unreliable.
Litigation timeline

Docket data
Four dated JPML snapshots trace MDL 3094 from 1,521 to 3,848 pending actions, while keeping the newer NAION docket and state cases out of the total.
Evidence review
Delayed gastric emptying is an intended pharmacologic effect. Gastroparesis is a clinical disorder. Here is how trials, observational studies and current FDA labels fit together.
Vision injury litigation
MDL 3163 is separate from the gastrointestinal GLP-1 litigation. Its central question is whether specified medicines can cause NAION, a rare optic-nerve event on which current studies disagree.
FDA label history
Ozempic, Wegovy, Mounjaro, and Zepbound do not share one label. This timeline explains major approvals and safety-language changes without treating a revision as proof of an individual injury.
