Ohio Rev. Code § 1333.30
If a customer does not take possession of a die, mold, pattern, or form located in this state within three years of the date it was last used, and no agreement in writing between the customer and the molder is made to the contrary, all of the customer's rights and title to, and interest in the die, mold, pattern, or form may be transferred to the molder for the purpose of destroying such die, mold, pattern, or form. In order to effect a transfer, a molder shall send notice by certified mail, return receipt requested, to the customer at the address, if any, indicated in the agreement pursuant to which the molder gained possession of the die, mold, pattern, or form, and to the customer's last known address indicating the molder's intention to transfer all of the customer's rights and title to, and interest in a die, mold, pattern, or form. All of a customer's rights and title to, and interest in a die, mold, pattern, or form shall transfer to the molder unless within a period of one hundred twenty days of the date the molder receives a completed return receipt or a report of nondelivery of the notice, the customer takes possession of or arranges with the molder to take possession of or store the die, mold, pattern, or form. Subsequent to such period and consistent with federal patent and copyright law, and any applicable state or federal law pertaining to unfair competition, a molder may destroy a die, mold, pattern, or form.
