This course covers how law regulates the content of Internet (cyberspace) communications. Half the course deals with the protection of content by intellectual property laws and half to forms of liability for supposedly objectionable or harmful content. Various themes recur : the liability of ISP and other third parties for actions by others; the role of technology in providing protection; self-regulatory and co-regulatory models; the emergence of international standards; problems of jurisdiction and regulatory arbitrage. Topics will include: Copyright and related protections (hypertext linking, search engines, etc); Internet process patents; database protection (copyright and sui generis rights); law concerning technological protection (DRMS, anti-circumvention and RMI laws); censorship; defamation; and tortious liability (negligent misstatements; 'trespass to chattels).
