An anti-plug molding law is a statute, usually a state law, that prohibits the use of an original product, such as a boat hull, as a "plug" for making a mold to use to make copies of the original product. The "plug" is the core around which the walls of the mold are formed and the contours of which the mold replicates in reverse.
This law prohibits people from unfairly copying a product
Definitionally, it prevents the production of the mold for copying an existing product
