Here are the lecture materials for Class 4 and the Attendance Certificate. There is a video lecture and also an audio-only lecture, as well as some external videos. In this class we move into how traditional areas of private law relate to the Internet. First, we look at online contracts and the problem of clickwrap and browsewrap agreements, then we discuss the role of patents and copyrights in cyberspace. Think about how to connect these legal regimes with the various theoretical considerations we discussed over the past two weeks. Note that the audio lecture mentions trademarks and domain names, but we will cover those IP aspects of cyberspace next week.
