Work highlights
Delivered a blockbuster $407m jury verdict for Regeneron Pharmaceuticals in a high-profile antitrust case involving cholesterol-lowering drugs.
Won a decisive dismissal of PepsiCo in a novel lawsuit, alleging that PepsiCo, and several of the nation’s most iconic food manufacturers, intentionally designed and marketed so-called “ultra processed” foods (UPFs) to be addictive to children, causing chronic diseases. This “first-of-its-kind,” high-stakes case is expected to test novel legal theories that could shape future decisions in similar cases and open the door to a wave of similar cases against food manufacturing companies worldwide.
Secured a landmark victory for Sirius XM Radio, securing a precedent-setting dismissal in a highly publicized litigation filed by SoundExchange over Sirius XM’s royalty calculations. It marked the first time a court has ruled that SoundExchange—the entity designated by Congress to collect and distribute royalties for music artists—lacks the enforcement authority to bring a litigation for alleged underpayment of royalties. This remarkable win, involving more than $150m+ in disputed royalties, is poised to reshape copyright enforcement and foster a more cooperative, less adversarial regime for resolving disputes.
