2 years from discovery of injury
Where to File in Illinois
Dupixent CTCL cases in Illinois are filed in the Northern District of Illinois (Chicago) or in Cook County Circuit Court. The Northern District has a dedicated complex litigation program and has managed major pharmaceutical MDLs. Cook County is historically one of the most plaintiff-favorable state court venues in the country. Illinois eliminated its tort reform damage caps when the state Supreme Court struck them down in Lebron v. Gottlieb Memorial Hospital (2010), meaning there are no statutory caps on compensatory or punitive damages in product liability cases.
