must be a written agreement between the parties specifying that the work is a work made for hire by use of the phrase "work for hire" or "work made for hire." In other words, mutual agreement that a work is a work for hire is not enough. Any agreement not meeting all of the above criteria is not a valid work for hire agreement and all rights to the work will remain with the creator. Further, courts have held that the agreement must be negotiated, though not signed, before the work begins. Retroactive contractual designation as a work for hire is not permitted. When relying on agreements in which creators transfer rights to a hiring party (copyright transfer agreement), a hiring party often finds that it has only limited scope to alter, update, or transform the work. For example, a motion picture may hire dozens of creators of copyrightable works (e.g., music scores, scripts, sets, sound effects, costumes) any one of which would require repeated agreements with the creators if conditions for showing the film or creating derivatives of it changed. Failing to reach agreement with any one creator could prevent the showing of the film entirely. To avoid this scenario, producers of motion pictures and similar works require that all contributions by non-employees be works made for hire. On the other hand, a work for hire agreement is less desirable for creators than a copyright transfer agreement. Under work for hire, the commissioning party owns all rights from the very start even if the contract is breached, whereas under a transfer of rights, the creator can hold back the rights until all terms of the contract are fulfilled. Holding back the rights can be a forceful tool when it is necessary to compel a commissioning party to fulfill its obligations. An author has the inalienable right to terminate a copyright transfer 35 years after agreeing to permanently relinquish the copyright. However, according to the US Copyright Office, Circular 9 "the termination provisions of the law do not apply to works made for hire." These restrictions, in both the work for hire doctrine and the right of termination, exist out of recognition that artists frequently face unequal bargaining power in their business dealings. Nonetheless, failure to secure a work-for-hire agreement by commissioning organizations can create difficult situations. One such example is the artist Raymond Kaskey's 1985 statue Portlandia, an iconic
