Moderated by Professor Michael Carroll

American University Washington College of Law regularly invites counsel of record and counsel for selected amici to offer post-argument reflections in intellectual property (and related) cases heard by the Supreme Court. These events are held on the afternoon of oral argument before the Court. 


Issues: (1) Whether a defendant that provides generic, widely available services to all its numerous users and “regularly” works to detect and prevent terrorists from using those services “knowingly” provided substantial assistance under 18 U.S.C. § 2333 merely because it allegedly could have taken more “meaningful” or “aggressive” action to prevent such use; and (2) whether a defendant whose generic, widely available services were not used in connection with the specific “act of international terrorism” that injured the plaintiff may be liable for aiding and abetting under Section 2333.
