Patents provide the exclusive right to own, use, and dispose of an invention for a limited time period of 20 years. They encourage innovation by allowing inventors to enjoy monopoly profits from their inventions and disclose their work publicly rather than keeping it secret. This disclosure can attract investors and help companies increase their value and market share by reducing competitors. Patents can be obtained by individuals or jointly for inventions, utility models, or designs. Trademarks differ in that they protect brands and logos legally through registration, establishing the exclusive property of the seller for 10 year periods.
