A more thorough explanation:

A legal monopoly is a situation where a business or individual has exclusive control over the production or sale of a particular product or service within a given region. This means that there is no competition in the market, and the monopolist can set prices and control supply without fear of losing customers to competitors.

Examples of legal monopolies include:

• Public utilities, such as electricity, gas, and water, which are granted exclusive rights by the government to provide these services to consumers.
• Patents, which give inventors the exclusive right to make, use, and sell their inventions for a certain period of time.

For instance, a company that holds a patent for a new drug can charge high prices for it because there are no other companies producing the same drug. Similarly, a public utility company can charge whatever rates it wants because it is the only provider of that service in the area.

Legal monopolies can be beneficial in some cases, such as when they encourage innovation and investment in new technologies. However, they can also lead to higher prices, reduced quality, and less choice for consumers.
