Practice area:


Michael P. Addis is a partner in Cravath’s Litigation Department. He focuses his practice on complex civil litigation related to general commercial, contractual, securities, shareholder derivative, antitrust and mergers and acquisitions disputes. 

Mr. Addis represents The Williams Companies and members of Williams’s Board in a lawsuit in Delaware relating to the company’s now terminated $37.7 billion combination with Energy Transfer Equity. He also represents Biogen in a qui tam action in Massachusetts federal court alleging violations of the False Claims Act and Anti Kickback Statute. 

Mr. Addis has also represented Qualcomm in several matters relating to the company’s patent licensing and chipset businesses, including an antitrust suit filed by the Federal Trade Commission. In August 2020, in a complete defense victory for Qualcomm, the Ninth Circuit unanimously reversed the district court’s prior judgment and vacated a permanent, worldwide injunction that had prohibited several of Qualcomm’s core business practices. 

Mr. Addis devotes a significant portion of his practice to pro bono service. Among other matters, he argued before the Third Circuit en banc and helped achieve a ruling on an important issue of criminal constitutional rights law, representing amicus curiae Amachi, Inc., a nonprofit organization that tutors children of prisoners, in connection with Jermel Lewis’s appeal of his criminal sentence. The U.S. Court of Appeals for the Third Circuit, sitting en banc, vacated Mr. Lewis’s sentence (reversing its own prior decision) and remanded for resentencing. 

Mr. Addis received an A.B. magna cum laude in English from Princeton University in 2005. He received a J.D. from Harvard Law School in 2010. Mr. Addis joined Cravath in 2011 and in 2013 he served as a law clerk to Hon. Kermit V. Lipez of the U.S. Court of Appeals for the First Circuit. He rejoined Cravath in 2014 and was elected a partner in 2019.
