The "E-Commerce and TechLaw Blog" has a nice summary of a court decision released today. In short, it affirms that plagarism detection services (like turnitin.com, the defendant in this suit) do not violate the copyrights of students when they archive their papers in order to compare them to other papers for detecting plagarism.
The page above has a nice brief summary, along with links to the Fourth Circuit court decision (which is surprisingly readable!). It applies the famous "four-part test" for determining fair use, exploring all the arguments for and against each test. It's a really nice piece of work.
This may end up being a part of my Computing Professional course next term.
