As the jury resolved all of the liability-related questions in plaintiff's favor, the focus of his motion is solely on damages. It must be considered in light of Section 504(b) of the Copyright Act,18 which permits a successful infringement plaintiff to recover "any profits of the infringer that are attributable to the infringement" and that are not included in computing actual damages. It goes on to say that "the copyright owner is required to present proof only of the infringer's gross revenue, and the infringer is required to prove his or her deductible expenses and the elements of profit attributable to factors other than the copyrighted work.
