Answer:
patented products
Explanation:
A patented product is one that has gone through a public concession process that has ruled that a particular company or manufacturer has exclusivity in the manufacture and distribution of that product on the market.
There is a concern about the existence of patented products in relation to genetically modified organisms, because this may prohibit the manufacture of similar products.
