The distinction between a new product and a minor modification to an existing product is not always clear. Certain products have a product life cycle in which the supply and demand for the product increases then decreases over time. The demand for certain food products such as bread will tend to increase with population, but the supply and demand for a specific brand of bread may decline over time. In the United States, a patent for a product is recognition that the product is new in a legal sense. Product identification codes such as Universal Product Code, Global Trade Item Number and International Standard Book Number allow multiple businesses to use a single product identification code to indicate one unit of a mass-produced product.
