Hon. Leonard B. Sand, U.S. District Court, S.D. New York (2011-2012)
Hon. John T. Noonan, Jr., U.S. Court of Appeals, Ninth Circuit (2013-2014)

Pieter de Ganon focuses his practice on complex commercial and intellectual property litigation and arbitration, with a particular emphasis on patent licensing disputes. Mr. de Ganon litigates cases relating to a wide range of technologies, including semiconductor design and manufacture, wireless broadband communications, rare-earth magnets, and optical lithography. He represents companies in suits arising from actual or potential mergers, acquisitions, and other strategic transactions. And he defends clients in commercial disputes in arbitration proceedings seated in common law and civil law jurisdictions under the rules of the ICC, ICDR, JCAA, and JAMS. Resident in the firm’s Tokyo office through 2017, Mr. de Ganon’s representative Japan-based clients include SoftBank, Hitachi, Toshiba, Renesas, Yahoo Japan, Sanyo, Nikon, and Fujifilm.

Mr. de Ganon is also involved in the firm’s extensive pro bono practice in Japan and the United States. He was part of the Tokyo-based pro bono team that secured asylum in Japan for an Afghan engineer—a significant victory given that Japan grants refugee status to just 0.3 percent of applicants. More recently, he was part of the core team that secured a preliminary injunction requiring the U.S. Customs and Border Patrol to improve conditions in its Arizona detention facilities. Through court-ordered expedited discovery, the team obtained photos of the conditions, which were later widely publicized. For this work, Mr. de Ganon was awarded the Wiley W. Manuel Certificate for Pro Bono Legal Services by the State Bar of California. The MoFo team was awarded the MLK Award for Civil Rights Advocacy by The Lawyers' Committee for Civil Rights of the San Francisco Bay Area, The American Heritage Award by The American Immigration Council, the Courageous Luminaries Award by the National Immigration Law Center. 

Before entering private practice, Mr. de Ganon served as law clerk to Judge Leonard B. Sand of the U.S. District Court for the Southern District of New York and Judge John T. Noonan, Jr., of the U.S. Court of Appeals for the Ninth Circuit.

Mr. de Ganon graduated from the New York University School of Law, where he was a Furman Academic Scholar, received the David Friedman Memorial Award in evidence law, and served as an articles editor for the New York University Law Review. Mr. de Ganon received a B.A., magna cum laude and Phi Beta Kappa, from Columbia University and a Ph.D. from Princeton University. He also attended Tokyo University as a Japanese Ministry of Education Scholar and Kyoto University as a Fulbright Scholar.

While in Tokyo, Mr. de Ganon taught law at Hitotsubashi University’s Graduate School of International Corporate Strategy. He speaks Japanese and Dutch.

SanDisk v. Toshiba Corporation (multijurisdictional litigation).
Represented Toshiba Corporation in its litigation and arbitration against SanDisk regarding a dispute over the Japanese firm’s plans to sell its $18 billion chip unit. The dispute involved three California state court proceedings, two Tokyo district court cases and three International Chamber of Commerce arbitrations. The matter was settled favorably after Toshiba successfully obtained favorable rulings before the California state court and the arbitral tribunal.

Confidential Arbitration.
Represented a multinational corporation in a multibillion dollar contractual dispute regarding the scope of a patent cross-license agreement.

Certain Sintered Rare-Earth Magnets and Products Containing Same (ITC, 337-TA-855).
Represented complainant Hitachi Metals and its U.S. affiliate in a landmark investigation involving 29 respondents before the U.S. International Trade Commission regarding infringement of certain Hitachi Metals patents by the sale into the United States of certain sintered rare-earth magnets. Following favorable settlements with virtually all respondents, the investigation was terminated by Hitachi Metals prior to trial.
