Nicci represents companies big and small in competition-related disputes.


Nicci's experience in some of the largest class action cases in the U.S. has taught her how to find effective solutions for her clients, even in large-scale litigation.

A self-professed nerd, Nicci has a passion for helping clients understand how antitrust and other trade practices laws apply to new and emerging technologies. Clients benefit from the unique insights Nicci has gained by litigating both antitrust and intellectual property claims. Her devotion to writing a winning brief is matched only by her zeal for conducting a strong cross examination. 


Fortune 500 companies and other corporate clients trust Nicci’s advice on antitrust issues such as pricing, internet sales, grey-market goods, and licensing issues.

Nicci is currently defending clients in two nationwide antitrust and consumer-protection class actions related to alleged information sharing in two different agricultural industries.

She defended a pharmaceutical manufacturer against claims related to the settlement of intellectual property litigation.

She also defended a national health care insurer in multi-district litigation brought by putative nationwide classes of medical providers and insurance subscribers asserting RICO and antitrust claims.

Nicci’s other trade practices work spans from representing a high-tech financial services company in a Federal Trade Commission investigation to defending companies in litigation involving allegations of software trade secret misappropriation, unfair-trade-practices claims, and claims under the Lanham Act.

Nicci has successfully defended a number of companies against claims brought under the Missouri Merchandising Practices Act.

Nicci took the lead in writing the brief that persuaded the Seventh Circuit to vacate the largest class ever certified in an ERISA class action.

Twice, she represented three former U.S. Attorneys General as amicus curiae before the U.S. Supreme Court.

She also represented media organizations as amicus curiae before the Missouri Supreme Court.
