What an MDL is
When many people file similar federal lawsuits against the same company, the Judicial Panel on Multidistrict Litigation (JPML) can send them all to one judge for pretrial work such as evidence gathering and expert rulings. Each case stays a separate lawsuit, unlike a class action. A few cases are often tried first as “bellwether” trials, and cases that don’t settle or get dismissed can be sent back to the court where they were filed for trial.
The case counts above only include federal cases. Similar claims can also be filed in state courts, and those are not counted here.
Thinking about a claim? Whether you can join depends on your own facts and on deadlines that vary by state. A lawyer who handles class actions cases can tell you whether you qualify.

Source: case counts, judges and courts come from the monthly “Pending MDL Dockets” reports published by the United States Judicial Panel on Multidistrict Litigation. We update them each month. “Pending” means cases still open in the MDL; “total” counts every case ever sent to it, including those since dismissed, settled or sent back to their original courts.
