ABA: Our Curious Amalgam: Where to Draw the Line? Intersection of 1st Amendment and Antitrust Under Noerr-Pennington Doctrine

October 13, 2025

O’Melveny partner Sergei Zaslavsky co-hosted this episode of the American Bar Association’s podcase series, ‘Our Curious Amalgam’ with Derek Jackson. 

“The Noerr-Pennington doctrine is rooted in the First Amendment and exempts certain activities involving petitioning the government from the normal rules of antitrust enforcement. But where do we draw the line on what activity is and is not protected? Abraham Chang, partner at Norton Rose Fulbright, joins Derek Jackson and Sergei Zaslavsky to discuss the Noerr-Pennington doctrine's roots, its limits, and how it gets applied (and sometimes litigated) in practice.”
