A monopoly power is defined as the ability of a business to control a price within its relevant product market or its geographic market or to exclude a competitor from doing business within its relevant product market or geographic market. It is only necessary to prove the business had the "power" to raise prices or exclude competitors. The plaintiff does not need to prove that prices were actually raised or that competitors were actually excluded from the market.
Today, a general definition of a monopoly is where nearly all of one product type or service is owned by one person or group of people within a community or area. Thereby, the sole control of this product or service is given to one party to the elimination of all others within the marketplace. To determine whether purchasing a competitor's business or creating an agreement with a competitor may result in a monopoly within your market place, please seek the advice of an attorney.
