Attorneys evaluating mass tort litigation in 2026 focus first on eligibility, causation proof, and filing deadlines. Mass torts are individual injury claims that share product or exposure facts and move through coordinated pretrial proceedings. This guide explains how that coordination works and what documents decide whether a claim can proceed. It covers proof of use and diagnosis, medical causation evidence, and cutoff dates that bar late claims.

How does coordinated federal litigation work?
Federal cases that share product or exposure facts are centralized in multidistrict litigation for coordinated pretrial work. According to the Judicial Panel's September 1, 2026 pending MDL statistics, 21 large MDLs held 94.5% of pending actions, including about 69,250 Johnson and Johnson talc cases. Under 28 U.S.C.
Sec. 1407, MDL judges handle discovery and motion practice and select bellwether cases for trial. A 2008 bellwether paper by Fallon, Grabill and Wynne hosted by the Judicial Panel explains that those trials test evidence and claim value. Results generally do not bind non-tried plaintiffs absent consent.
Who qualifies as an eligible claimant?
Eligibility turns on place, time, product use, and diagnosis, not on joining a headline case. The Department of Veterans Affairs' Camp Lejeune eligibility page requires at least 30 days at Camp Lejeune or MCAS New River from Aug. 1, 1953 to Dec.
31, 1987 plus a listed presumptive condition. That VA model shows the records attorneys request in other product cases: Bring complete pharmacy, medical, and work records to review. Gaps in use dates or alternate causes often decide whether counsel accepts the claim.
- proof of presence, prescription, purchase, or employment exposure
- dose, duration, dates of use, and product identification
- diagnosis records linking the listed injury to the exposure period
How is causation tested?
Causation evidence centers on the specific injury mechanism for each product, coordinated separately by MDL. For Ozempic and GLP-1 cases, the focus is gastric injury. The FDA-approved Ozempic label adds ileus risk and states Ozempic is not recommended in severe gastroparesis, as shown in the FDA's January 2025 Ozempic prescribing information, with cases coordinated in MDL 3094 in Pennsylvania. For Depo-Provera, the issue is meningioma after repeated long-term use.

HMF Law's summary of FDA action reports that the FDA approved a U.S. meningioma warning in Dec. 2025 directing clinicians to monitor for signs and discontinue the drug if diagnosed. Ask how your prescription history, imaging, and pathology match the warned-for use pattern.
Which deadlines control your options?
Some litigation tracks are closed to new administrative filings even while pending cases continue. The Navy states the Camp Lejeune Justice Act filing deadline was Aug. 10, 2024 and it is no longer accepting new administrative claims, detailed on the Navy's Camp Lejeune Justice Act claims page, so only timely filers can advance existing litigation-track cases. Other tracks remain active but move through staged bellwether work.
The JPML Aug. 3, 2026 count and an Oct. 2026 TorHoerman Law update report about 15,246 pending actions in AFFF firefighting-foam MDL 2873 in South Carolina, with personal-injury bellwether work continuing and no global personal-injury settlement reached. Filing, tolling, and court-ordered cutoff dates still control individual rights during that work.
What should you ask counsel before filing?
Ask how the firm will prove individual use, dose and duration, diagnosis, and alternate causes. The text of Federal Rule of Evidence 702 published by GovInfo requires sufficient facts and reliable methods for expert testimony, so ask which expert supports your injury theory and what records that expert needs. Confirm case handling in writing: Bring pharmacy records, work history, and prior imaging to that first review.

- who handles intake, expert development, and court appearances
