Major joint authorship decision in the Second Circuit this week in Davis v. Blige. Summary in the New York Law Journal here. Shorter summary from Eugene Volokh: "You can get a nonexclusive license up front from just one [co-owner], without the others' permission. But once you infringe you can't get a retroactive license from just one -- you'd have to get forgiven by all of them."
Bill Patry says the decision is "disastrous" and is hoping for a do-over.
