A graduate of Harvard University and Yale Law School, John began his legal career at O’Melveny & Myers LLP.  He is the author of dozens of articles and two books:  Infringement Nation (Oxford University Press, 2011), which the Harvard Law Review has praised for its “insightful critique of the copyright regime” and “convincing case for . . . reform,” and Whitewashed (New York University Press, 2009), which Publisher’s Weekly has lauded as a “consistently informative” work that “covers fresh legal and social territory.” His work has appeared in such publications as the Yale Law Journal, Northwestern University Law Review, George Washington Law Review, Iowa Law Review, Berkeley Technology Law Journal, and the Chronicle of Higher Education.

A frequent commentator for the broadcast and print media, he has appeared on such television programs as ABC’s Nightline and has been quoted as an expert on legal issues in such publications as The New York Times, Harper’s Magazine, Financial Times, Los Angeles Times, Hollywood Reporter and Christian Science Monitor.  He has spoken at numerous national and international conferences and venues, from the National Baseball Hall of Fame and Museum, MAK Center for Art & Architecture and the American Intellectual Property Law Association to the Royal Institute of Technology (Stockholm), Humboldt University (Berlin) and Monash University (Melbourne).  His work has been widely cited, from testimony before the United States Congress and decisions of the Israeli courts to briefs before the United States Supreme Court in such landmark intellectual property cases as MGM v. Grokster, Tiffany v. eBay, and Golan v. Holder and such leading legal publications as the Yale Law Journal, Harvard Law Review and Nimmer on Copyright.
