I linked the other day to Sergio Muñoz Sarmiento's post on the art law case of the decade. Daniel Grant, author of The Business of Being an Artist, emails his choices:
"My votes would be for the [Phillips] case in Boston, which goes to the heart of what is site-specific and whether or not the law covers that art world term, and the Daniel Moore case in Alabama, which may turn back a growing effort on the part of numerous colleges to claim anything associated with them as trademarked."
