If a customer does not claim possession of the particular die, mold, or form within 120 days following the date the notice was sent, or does not make other contractual arrangements with the molder for storage thereof, all rights and title of the customer shall transfer by operation of law to the molder. Thereafter, the molder must destroy the particular mold, die, or form as the molder’s own property without any risk of liability to the customer, except that this Section shall not be construed in any manner to affect any right of the customer, under federal patent or copyright law or any state or federal law pertaining to unfair competition.
