I know there are several teachers on my f'list; I'm hoping some of them (or their associates) will have stories or even documented incidents related to this.

Seeking stories of copyright misuse:The Glushko-Samuelson Intellectual Property Law Clinic at American University is working with the Computer & Communications Industry Association (CCIA) on a FTC complaint against major content providers including the NFL, the MLB, Universal, DreamWorks, Harcourt Inc., and Penguin Group. The CCIA alleges that these corporations have engaged in a nationwide pattern of unfair and deceptive trade practices by misrepresenting consumer rights under copyright law by posting misleading and overreaching copyright warnings.
The Clinic is looking for anyone who has been injured or affected by these overreaching copyright warnings. That is people who chose not to use a particular work or modified their use of that work after reading the attached overreaching copyright warning. For example, a teacher who chose not to use a television, movie, or music clip in the classroom out of fear that his or her actions violated copyright law.
