Professor Nimmer has a good post
on the Supreme Court's decision in the much-discussed EBay patent case
yesterday (which includes some discussion of copyright as well). His bottom line: "So, what happened here? Very little. In my view, the most important result is that the Court affirmed the right of a property owner to prevent use of its property in most cases. The risk avoided by the Court was that this case would be a vehicle to diminish the strength of patents and copyrights as property. The Supreme Court got it right by rejecting that result."
