Lex Machina is excited to announce the release of its Law Firms Activity Report. The report looks back at the last three years and analyzes law firm activity in 15 practice areas and in cases caused by COVID-19. The final section of the report includes a comprehensive look at civil litigation in federal district court. 

Highlights from the report:

  • The Department of Justice was far and away the most active counsel in the last three years, filing nearly 9,000 cases on behalf of plaintiffs and defending over 27,000 cases when excluding multidistrict litigation associated cases. 
  • Gottlieb & Associates filed the most lawsuits caused by COVID-19 on behalf of plaintiffs in 2020 (230 cases). The firm filed many lawsuits under the Americans with Disabilities Act (ADA), which are part of Lex Machina’s Remaining Federal case type. 
  • Multidistrict litigation, class actions, and suits related to one particular event were influential in the overall landscape of litigation. These suits account for big case counts particularly in product liability, torts, and insurance practice areas.
  • While law firms with big case counts tended to have dedicated specializations, there were several national litigation firms that appeared across different practice areas.
