National dispute resolution boutique MoloLamken LLP continues to strengthen its formidable record before the US Supreme Court; it argued three SCOTUS cases during the 2022/23 term, despite the Court’s shrinking docket overall. The firm’s emphasis on high-profile appeals involving IP, energy, telecoms and sovereign immunity also ensures that it is frequently engaged to represent clients before various courts of appeals. Highlighted by sources as a ‘great senior partner’, appellate chair Jeffrey Lamken has argued twenty-seven cases before SCOTUS. Among Lamken’s recent cases, he represented The Humane Society of the United States before the US Supreme Court in a successful defense of California’s Proposition 12 against a constitutional challenge. Next-generation partner Lucas Walker recently argued—and won—his first case before SCOTUS, when he represented Abitron Austria in a precedent-setting trademark case holding that US trademark law is not extraterritorial and applies only to uses of trademarks within the US. The team also includes experienced appellate litigator Michael Pattillo, who is noted for his record in patent appeals before the Federal Circuit; Robert Kry, whose practice spans trial and appellate litigation; and Rayiner Hashem, who focuses on appellate and patent litigation. Named attorneys are based in Washington DC.
