Why should I file a utility patent application?

Although inventors generally understand that they should patent their work, most do not understand why. The main reason to file for protection is that a utility patent gives an inventor a limited monopoly - it grants him or her the right to prevent anyone else from making, selling or using the invention without the inventor's consent. If someone makes, sells or uses the patented item without permission, a patent holder can bring an infringement lawsuit and often collect significant damages.
