A provisional patent application allows inventors to secure a filing date for their invention without needing a complete application, providing temporary protection and 'patent pending' status for 12 months. This application is simpler and cost-effective, suitable for individual inventors and small businesses, while also enabling further development and market testing of the invention. However, it is crucial to file a non-provisional patent application within the 12-month period to maintain the priority date and ensure long-term protection.
