Tiffany Lipscomb-Jackson is a seasoned commercial litigator with substantial experience in the petroleum, pharmaceutical, and agricultural industries, with a focus on antitrust and competition issues. She has extensive experience with multijurisdictional and multiparty matters alleging bid-rigging, price-fixing, and illegal monopolization brought by private plaintiffs and state attorneys general.

Tiffany has more than a decade of experience defending clients in bet-the-company class action litigation in a wide range of cases, including antitrust, consumer protection, civil RICO, and breach of contract. She recently won dismissal for Chamberlain University in a breach-of-contract class action arising out of COVID-19 and successfully defended the dismissal on appeal to the Sixth Circuit. Other exemplary experience includes obtaining summary judgment for Marathon and excluding Kentucky's sole expert in a Sherman Act Section 1-2 case; obtaining summary judgment for a large client on Lanham Act claims; and representing National Beef in class action litigation involving its cattle procurement practices.

Tiffany has a robust pro bono practice, which includes successfully representing immigrants seeking relief before the United States Immigration Court and federal courts of appeal. She is also a board member for Lawyers Without Borders.
