IP - Copyright & Trademark
Where a first sale defense to copyright infringement is argued, the party asserting the defense has the burden to prove the sale, but the party claiming infringement has the burden to prove that the apparent sale was actually a license.
General testimony and generic licensing templates do not suffice for proof that a specific transaction was a license.
An assertion that goods were sold under the correct mark, but without the consent of the owner of the mark speaks to unfair competition, not infringement.
