Can copyright termination rights be addressed through mediation?

Yes. Under U.S. copyright law, authors (or their heirs) have the ability to terminate certain prior grants of rights after a statutory period, which can bring a creator and a company that has long exploited a work back to the table. Assuming the work qualifies and the notice is properly filed, there's no ownership dispute and no defect to cure. It simply creates an opportunity for a new deal that reflects the change in leverage: a renegotiated royalty, buyout, or renewed license. These situations are often better resolved by negotiation than litigation, because both sides usually have an interest in continuing to exploit the work profitably. Mediation allows them to negotiate a new arrangement giving each party the opportunity to create mutually desirable outcomes without the cost and uncertainty of litigating the underlying validity of the termination.
