Any excess shall next be paid to the molder who possesses a lien under this act in an amount sufficient to extinguish that interest. Any remainder shall then be paid to the customer.

  (2) A sale shall not be made under this act if it would be in violation of any right of a customer under federal patent or copyright law.
