- Represented Qualcomm Incorporated in numerous high‑stakes disputes and investigations around the world relating to the company’s patent licensing and modem chipset businesses, including:
- FTC v. Qualcomm Incorporated: A suit filed by the U.S. Federal Trade Commission (FTC) in California federal court alleging violations of Section 5 of the FTC Act and seeking a permanent injunction against Qualcomm. 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.
- Apple Inc. v. Qualcomm Incorporated: An action filed by Apple against Qualcomm in California federal court.

Jermel Lewis: 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. The court followed the analysis set forth in Mr. Addis’s argument and Cravath’s amicus brief, holding that it was harmful error in violation of Mr. Lewis’s constitutional rights to sentence Mr. Lewis for a greater offense than that for which he had been indicted, tried, jury‑instructed and convicted.
- Tevin Benjamin v. Mississippi: Argued before the Mississippi Supreme Court in the direct appeal of 14‑year‑old Tevin Benjamin’s capital murder conviction and life‑without‑parole sentence. The Mississippi Supreme Court vacated Mr. Benjamin’s conviction and sentence, finding that Mr. Benjamin was subject to interrogation after invoking his right to counsel, in violation of U.S. Supreme Court precedent Edwards v. Arizona.
- Terry Hye, Jr. v. Mississippi: Filed a petition for writ of certiorari in the U.S. Supreme Court, asserting that by instructing the jury on the elements of an underlying offense to capital murder not charged in the indictment, and failing to instruct the jury on all of the elements of the underlying offense charged in the indictment, the trial court constructively amended the grand jury’s indictment in violation of 16‑year‑old Mr. Hye’s constitutional rights.
