  • MGM, Universal, Paramount, and other major motion picture studios in the landmark MGM v. Grokster copyright case against the providers of file-sharing services.*

Securities Litigation

  • A mortgage servicing company before the Delaware Supreme Court and Delaware Chancery Court. Mr. Boyle argued the appeal that led to the landmark Central Mortgage decision clarifying Delaware’s pleading standard.*
  • Sprint-Nextel in a breach of contract action in Los Angeles brought by former Australian Prime Minister Paul Keating and a group of investors seeking US$200 million in connection with a mobile phone joint venture. After Sprint obtained sanctions twice against the plaintiffs, the plaintiffs dismissed their case with prejudice and made a payment to Sprint.*

The favorable verdict was reported in The Financial Times, Forbes, and Bloomberg.*
  • NBA Hall of Fame Coach Larry Brown in his US$50 million ad hoc arbitration against The New York Knicks, which was resolved after the merits hearing. The New York Post described Boyle as a “legal pit bull.”*
