He regularly represents clients in state and federal court, in private arbitration and before the Better Business Bureau’s National Advertising Division.

The advertising disputes in which Mr. Jirgal is involved often turn on cutting-edge technological issues, and the effective presentation of complex testing and statistical analysis. As an essential part of his practice, Mr. Jirgal also regularly oversees the design and critique of consumer perception surveys that can be dispositive in an advertising dispute involving implied claims.

Loeb & Loeb LLP‘s competitor versus competitor-focused practice spans its New York and Chicago offices, which house co-chairs David Mallen and Thomas Jirgal respectively. Mallen, a former deputy director of the National Advertising Division, is particularly notable for his work in relation to green or environmental claims, product testing, consumer surveys, and social media or influencer issues, as well as receiving instructions in the field of FTC and state regulatory investigations. Jirgal, meanwhile, focuses more on technological claims involving testing and statistical analysis, along with consumer perception issues in relation to implied claims. More broadly, the team handles federal Lanham act litigation, NAD representation and related appeals, along with its work in advertising-related IP, class actions, and investigations. Brian Heidelberger chairs the firm’s advertising, marketing and promotions group.
